Preliminary reports suggest that there were 1,305 reported tornadoes in the U.S. (of which 1,092 were confirmed), with 81 confirmed fatalities. It was the deadliest year for tornadoes in the U.S. since 1999, when 95 deaths were reported. In addition, three fatalities took place in Mexico, 14 in Chad, one in South Africa, three in Vietnam, one in the Philippines and 25 in China for a worldwide known total of at least 127.
The spring was also fairly active, with several significant tornado events in April and May, including a major outbreak in the first weekend of May producing the first ever EF5 tornado (and first F5 tornado on any scale in the 21st century). While June was not as active with fewer tornadoes, it produced another F5 tornado and Canada's first such tornado.
The tropics in the Western Hemisphere produced few significant tornadoes in 2007, but Typhoon Sepat produced a deadly tornado in China. Otherwise, the summer and early fall were fairly quiet, with a few local exceptions. The most severe outbreak in the second half of the year took place in October, when the largest outbreak ever recorded in that month took place.
The year ended slowly with no major outbreaks in November or December and only a few isolated tornadoes, mostly related to larger winter storms.

Damages from the tornadoes totaled to $8.32 Million.
A moderate severe weather event took place on February 23 and 24 across the south-central United States. It was expected to have been much larger, on February 23, as a moderate risk of severe weather was issued by the Storm Prediction Center for both days over large areas.
The activity on February 23 was quite modest due to a late start and low dew points. Six tornadoes were reported (and two were confirmed), and no significant damage was reported. The area primarily affected was the southern High Plains.
At least 13 tornadoes were confirmed on February 24. The strongest tornado was reported in Dumas, Arkansas, where buildings were destroyed or flattened, including an entire industrial park.

A slow-moving system developed across the High Plains on the dry line on March 28. A moderate risk of severe weather was issued by the Storm Prediction Center as widespread severe weather, including tornadoes, were expected throughout the afternoon and evening. In all, 65 tornadoes were reported in the region, with several destructive and large tornadoes taking place in numerous communities across the region. Many other severe weather reports came in, including hail as large as softballs. Five people lost their lives.
The system gradually moved east on March 29, but the squall line leftover from events the previous night prevented a major outbreak. Even so, four tornadoes were reported in Oklahoma, two in the Oklahoma City metropolitan area, which injured several people.
The SPC had issued a moderate risk again for March 30 and March 31 over portions of southern Texas. Few tornadoes were reported across the Midwest but one tornado hit midtown St. Louis causing damage to roofs, trees and signs including parts of a billboard sign that flew over and blocked Interstate 64.
187 tornadoes were reported in the US in April, of which 167 were confirmed.
Another severe weather outbreak took place on April 3, exactly 33 years after the Super Outbreak. However, damaging hail and wind were the primary effects, although 10 tornadoes were reported in Texas, Tennessee, Kentucky, Arkansas and Alabama. Nearly 400 reports of hail were reported throughout the day with the majority occurring during the afternoon hours in Missouri, Illinois, Arkansas and Kentucky with also reports of golf ball to baseball size hail. The majority of the wind reports were from a bow echo that developed across central Kentucky and Tennessee during the evening hours and causing damage to trees, power lines, antennas and trailers. A total of 10 tornadoes were confirmed; all of them were EF0 or EF1. No fatalities were reported, but several people were injured.
Damages from the tornadoes totaled to $2.73 Million.
A severe weather outbreak occurred across the eastern central states on April 11, exactly 42 years after the deadly Palm Sunday Tornado Outbreak. The system spanned from Illinois and Indiana down to the southern states spawning seven tornadoes, 4 in Indiana (two EF0, one EF1 and one EF2 ) and 3 in Alabama (all rated EF1). The system also created damaging winds and a great amount of hail.
On April 13, severe weather developed across the Southern Plains, with the first storms affecting north-central Texas. The Storm Prediction Center issued a moderate risk of severe weather for April 13 over portions of North Central, Northeast Texas, Southern Arkansas and Northern Louisiana. It was also issued for the central Gulf Coast for April 14. During the mid-afternoon hours, the moderate risk was upgraded to a high risk for the second time in 2007. In the Dallas-Fort Worth Metroplex, there have been a couple of unconfirmed tornadoes throughout the region. Hail as large as and wind gusts up to have been reported as well. One fatality has been reported although it may have been either from the tornado in Haltom City or from straight-line winds according to WFAA coverage. The tornadoes were reported in Seymour, Texas and Haltom City, Texas where one (or two) deaths has occurred. Two tornadoes of one EF0 and an EF1 tornado were later confirmed in Tarrant County near Fort Worth while another EF0 was confirmed in Dallas County and a third EF0 in Rockwall County. The severe weather caused cancellation of qualifying for the 2007 Samsung 500 at Texas Motor Speedway, forcing the field to be established via owner's points. Nonetheless, the overall activity was much lower than expected and the high risk busted.
For April 14, the Storm Prediction Center issued a moderate risk of severe weather for southern Louisiana, Mississippi, Alabama, Georgia and northwestern Florida. Several more scattered tornadoes were reported.
While most of the activity on April 15 was straight-line winds, an isolated EF3 tornado touched down in Sumter County, South Carolina that morning. Several mobile homes were demolished and one person was killed, with three injured. Two other tornadoes were later confirmed in South Carolina : an EF1 in Lee County and an EF0 in Orangeburg County. Several tornadoes also affected Georgia where at least 8 tornadoes and three injuries were documented.
On April 17, although the SPC issued a slight risk of storms, a storm system progressed through Texas. The system spawned ten tornadoes through northern Texas, such as Anton, Lubbock and Haslet, which is only a few miles from where a number of tornadoes hit the Friday before, April 13, 2007. The system also created penny to ping-pong ball-sized hail and created dangerous wind speeds. Six tornadoes were confirmed, one EF1 and the others all EF0.
Activity was not widespread on April 20, but eight tornadoes were reported in southwestern Nebraska, all from a single supercell that suddenly developed. Two have been confirmed as of April 23. A tornado near Moorefield, Nebraska has been rated EF3. It destroyed six farmsteads and had a path length of . Another EF2 tornado was confirmed in Dawson County, Nebraska, which was over wide at its peak but fortunately remained in sparsely populated areas.
On April 20, the SPC issued a moderate risk of severe thunderstorms for the Texas and Oklahoma Panhandles and the southwestern part of Kansas for April 21 which was extended into Nebraska later. Widespread severe weather developed that evening, although the primary result of the supercells was large hail. The meteorological synopsis was virtually identical to March 28 except for the fact that the air mass was not as unstable. In total, 19 tornadoes were reported. The hardest hit community was Tulia, Texas where many houses were reported to have been destroyed. That tornado was rated as a high-end EF2. Another strong tornado (also a high-end EF2) hit Cactus, Texas where significant structural damage was reported (including total destruction to at least 10 mobile homes) and 14 people were injured, but remarkably, no one was killed. The tornado was wide at its widest point.
Several tornadic storms were reported across northwest and south-central Texas, far western Oklahoma, and southwest Kansas on April 23. At least 29 tornadoes have been reported. Some were reported to have been large and powerful in the sparsely populated area. However, no injuries were reported.

Tornadoes, along with large hail and damaging winds, occurred in the afternoon and evening hours across the Plains. 22 tornadoes were reported. One large tornadic supercell also moved through Piedras Negras, Coahuila in Mexico, and moved into Eagle Pass, Texas, with reports of significant damage on the U.S. side of the border and at least seven deaths and 74 injuries from that EF3 tornado, plus at least three deaths and at least 40 injuries across the river in Piedras Negras. There was virtually no activity in the high risk area, however, and that busted.
Several tornadoes developed across the Midwest and into the Tennessee Valley on the afternoon and evening of April 26. The hardest hit communities were LaPorte, Indiana (by two EF1 tornadoes) and New Tazewell, Tennessee (also by an EF1 tornado where structural damage was reported in both communities, and dozens of houses were damaged or destroyed.

On the afternoon of May 2, supercells developed across several parts of Texas. 10 tornadoes were reported, including two in the city of El Paso, however, the damage was relatively minor. Tornado watches were spread throughout Texas. However, the supercells redeveloped into a hybrid derecho across Central and North Texas that evening, stretching from the Dallas-Fort Worth Metroplex to south of Waco and extending eastward to about Longview. Widespread wind damage with winds in excess of were reported. In the Metroplex, more than 300,000 customers lost power as a result of the high winds. Some of the most severe damage included the loss of a roof at an apartment complex, extensive tree and power line damage (with many trees crashing into houses) and flipped tractor-trailers and mobile homes.

152 tornadoes were reported in the US in June, of which 128 were confirmed.
A sudden string of supercells developed across eastern Iowa early in the afternoon of June 1 and tracked into northwestern Illinois and southwestern Wisconsin. The hardest hit communities were Muscatine, Iowa where widespread structural damage was reported, including businesses destroyed and injuries. Most of Grandview, Iowa was sealed off due to the extensive damage it sustained from the tornado. Houses were flattened in Grandview and people were reported trapped by the EF3 tornado. A second nearby tornado, rated EF2', also left significant damage around Bellevue, Iowa. No fatalities were reported.
A low pressure system moved across much of central and eastern North America starting on June 6 in the central Plains and into the Mississippi Valley, Great Lakes region and eventually the Northeast over the following few days. On June 4, the Storm Prediction Center issued a moderate risk of severe weather for June 6, only the fourth such issuance for a day three outlook. On the morning of June 5, the Storm Prediction Center continued the moderate risk for June 6 and issued a moderate risk for June 7 over much of the Upper Midwest, making it the fifth time a moderate risk has been issued on day 3. Both were forwarded to days 1 and 2, respectively, on June 6.
On June 6, there were two distinct threats forecast. The central Plains were expected to see a large tornado outbreak potentially, particularly in Nebraska and the Dakotas close to the dry line, should the cap have broken in the atmosphere in the afternoon hours. In the evening and overnight hours, a major derecho with destructive winds and some scattered tornadoes were possible farther east, particularly in the eastern Dakotas, western Minnesota and western Iowa. However, that basically busted as little severe weather happened as the cap held up in most areas. Only five tornadoes and scattered wind reports took place.
A high risk of severe storms was issued for June 7 for the Upper Midwest, from about the Quad Cities north to Lake Superior. Widespread tornadoes and destructive downburst winds were possible. A moderate risk was issued for portions of Minnesota, Michigan and Illinois while a slight risk was issued south towards Oklahoma, which was then upgraded to a moderate risk late in the day. Environment Canada also issued a risk of severe thunderstorms with possible tornadoes for all of northwestern Ontario and a severe weather watch was issued early Thursday morning from the Manitoba border towards the north shore of Lake Superior
There were 14 tornado reports that day. The most serious damage was near Mosinee, Wisconsin where a house was heavily damaged by an EF2 tornado, and in Wisconsin Rapids, Wisconsin where a weak tornado touched down in or near the downtown area, along with softball sized hail. However, farther south, the cap has held in place once again, restricting activity to the northern areas.
The largest confirmed tornado on June 7 was an EF3 that touched down in central Wisconsin. It was on the ground for while passing through Shawano, Menominee, Langlade, and Oconto counties. It was up to wide at times and took down 14,000 acres (57 km²) of forest, damaging dozens of buildings.
On June 8, Environment Canada issued a moderate risk of severe thunderstorms for Eastern Ontario with the risk of tornadoes. A Slight risk was issued for most of Southern and Northeastern Ontario. The slight risk zone extends from southern Quebec, near Montreal into northern Mexico During the noon hours, the moderate risk zone was extended further south to includes portions of western New York, western Pennsylvania, northern West Virginia, northern Kentucky, southeastern Indiana, most of Ohio and larger portions of southern Ontario from Windsor to eastern Ontario. It turned out to be a long squall line though, and while there was wind damage from winds as strong as stretching from the Tennessee Valley north to almost Hudson Bay, there were only two tornadoes, one near Brantford southwest of Toronto and the other near Bancroft north of Peterborough, Ontario.
A supercell that developed over the Nebraska/Kansas border produced extensive hail and at least 7 reported tornadoes on June 19. The storm that travelled southeast through Oklahoma and North Texas eventually became an Mesoscale Convective Complex dumping heavy rain across areas that had been hit with significant flooding.
A sharp cold front also produced widespread wind damage across the Great Lakes and the Northeast and at least one reported tornado.
A moderate risk of severe thunderstorms was issued by the Storm Prediction Center for portions of eastern Iowa during the late afternoon of June 21. 7 tornadoes were reported across the Plains as a large cluster of storms moved eastward. Several reports of large hail exceeding golf ball size was reported. The strongest tornado took place in Norwalk, Iowa, it was an EF2 which heavily damaged homes.
On June 22, more severe storms developed, this time primarily farther north. The most intense weather was across southern Manitoba where tornadoes were reported. The most severe damage was around Elie, Manitoba where several houses were flattened and numerous others damaged or destroyed. A flour mill was also destroyed and several trucks were overturned on Highway 1. The tornado path was long, and was initially rated as an F4 on the Fujita Scale, but was then rated as an F5 becoming the first tornado of its kind in Canada. Another tornado hit McHenry County, North Dakota; it was an EF1 with moderate damage, mainly to trees and farm buildings.
More tornadoes were possible across southeastern Saskatchewan, southern Manitoba and extreme northern North Dakota on June 23. The cap broke across the northern parts of the area and supercells formed that afternoon, primarily in Manitoba. At least five tornadoes were reported, including large wedge tornadoes. Fortunately, they missed populated areas for the most part. One of the tornadoes traveled south of Baldur, Manitoba and was rated an F3 on the Fujita scale. . The tornadoes were described as being "as bad as they ever get here in Canada" (referring to the F4 tornado) as meteorologist Dave Carlsen of Environment Canada told Canwest Global affiliate CKND-TV. However, the tornado in Elie was recently upgraded to F5, after Environment Canada determined that wind speeds were at least 420 km/h in video analyses of that tornado.
55 tornadoes were reported in the U.S. in July, however 69 were confirmed.
An outbreak of tornadoes occurred across New Zealand's North Island. Six were reported in the city of New Plymouth, Taranaki, devastating many houses and part of the Central Business District. Whakatane, Tauranga, and Auckland were also effected by tornadoes.

An unusual EF2 tornado struck New York City at 6:30 am EDT (1030 UTC) on August 8. The hardest-hit areawas the Bay Ridge area of Brooklyn, where many trees—as much as 40% of the trees in Sunset Park were knocked down and several homes and buildings lost part of their roofs. A second tornado was also confirmed just east of the track of the first tornado and rated as a strong EF1 where additional roofs of homes were damaged. The Flatbush neighborhood, as well as areas on Staten Island, were also affected.
Accompanying the tornadoes was a storm which dumped several inches of rain on the city in a few hours, resulting in flooding which effectively shut down the mass transit system. Several people were injured by the tornado, and one person died from the associated flooding. The tornado was the first to hit Brooklyn since 1950 when modern record-keeping began.
At the northern boundary of a heat wave, severe thunderstorms developed on the afternoon of August 9 in Ohio and western Pennsylvania. Several sudden supercells developed with at least four tornadoes reported, primarily around Akron, Ohio. Significant damage was reported, including roofs removed from a high school and a factory, as well as numerous houses. Widespread straight-line wind damage was also reported. One person was killed by a fallen tree limb in Marion, Ohio, although it is unclear if it is due to a tornado or straight-line winds.
In Pittsburgh, a funnel cloud was spotted downtown near the Carnegie Science Center, shattering windows and evacuating the 1000 patrons to the lower level. The museum was closed until August 13. Over 90,000 homes and businesses were without power, some not receiving it until August 12.
One person was killed when a tornado had struck Zambales, Philippines. Several homes were also heavily damaged or destroyed.

The National Weather Service office in Grand Rapids, Michigan, confirmed that two EF1 tornadoes hit rural Montcalm County near Cedar Lake. Non-tornadic severe thunderstorms also did serious damage in Berrien, Van Buren, Kalamazoo, and Allegan counties.
On August 24, following conditions similar to the previous day, an EF3 tornado with "winds near " formed two miles (3 km) north of Charlotte, Michigan, doing severe damage along Vermontville Highway, passing through Potterville, and crossing I-69 in Eaton County before dissipating as it approached Dimondale, touching down around 4:25 PM EDT and leaving a damage path varying from to wide and long.
Around 4:55 pm EDT, the same storm produced an EF1 tornado which touched down at the intersection of Waverly Road and M-99 in southeastern Lansing, extending across I-96, towards the intersections of Aurelius Road with Jolly Road and Dunkel Road before finally dissipating near the Jolly Road interchange on I-496.
Other storms in the same system later produced tornadoes in the NWS Detroit/Pontiac office coverage area. The most powerful one was a "strong EF2" that touched down in Cohoctah Township, Livingston County, Michigan at around 5:30 PM EDT. Remaining on the ground for , with an average track width of and a maximum track width of one-quarter mile in the city of Fenton, Genesee County, the funnel continued through Deerfield Township and northwestern Tyrone Township before entering Genesee County and the city of Fenton, where it caused the partial collapse of "a large retail structure" at the intersection of Owen Road and US-23. It then passed on into Holly, in Oakland County before dissipating into straight-line winds east of Holly.

Numerous reports of straight-line wind damage were also received throughout the entire NWS Detroit/Pontiac coverage area.
The storms in this system were part of the same system that sat over the Midwest Areas for almost a week, bringing pouring rain at first then the Severe Weather later in the week. This storm system and stationary front is also blamed for the flooding in the Ohio area.
A rare tornado occurred in the capital of Colombia, Bogotá, and was caught on tape. There were no immediate word on any damage or injuries. Much of western Colombia lies along the Andes mountain chain which limits tornado activity in that region. However, in June 2001 a tornado killed six people and injured 350 in the town of Barranquillia in extreme northern Colombia.
An isolated tornado event produced at least four tornadoes in eastern North Dakota and northwestern Minnesota on the evening of August 26, 2007. One of the tornadoes was very destructive and did widespread damage in Northwood, North Dakota. One fatality occurred in Northwood and multiple structures were damaged or destroyed including a mobile home park and the community's hospital, school, and fire hall. This was the first killer U.S. tornado since May 5, 2007. 18 other people were injured by the tornado, which was about 0.8 mile (1.3 km) wide. Surveys confirmed it to be an EF4 tornado; the fifth violent US tornado of 2007.
63 tornadoes were reported in the US in September, of which at least 51 were confirmed.
An undeveloped tropical low over the Gulf of Mexico (which later became Tropical Depression Ten) spawned one confirmed and several possible tornadoes late on September 20 and early on September 21 over parts of central Florida, not far from areas devastated on February 2. The hardest-hit community was Eustis, Florida where at least 50 houses were damaged, many of which were destroyed. Looting was reported in the community after the tornado hit. No serious injuries were reported by the EF1 tornado.
Severe thunderstorms developed across the Midwest on September 30. Several tornadoes touched down, the strongest being an EF2 tornado near Sully, Iowa, which was 22 miles (35 km) long and up to 0.7 mile (1.1 km) wide at its peak. Heavy damage was reported to several houses and industrial buildings from the largest of the tornadoes. Several injuries were reported in Pike County, Illinois due to mobile home damage from an EF0 tornado there.
