1914 Atlantic hurricane season

The 1914 Atlantic hurricane season was the least active Atlantic hurricane season on record, in which the season lasted for only 5 days. Although the season normally runs through the summer and the first half of fall, actual activity in the season was confined to the middle of September. The season produced one tropical storm that reached a peak intensity of 70 mph (110 km/h). The 1914 season is one of only two hurricane seasons on record that did not produce any hurricanes, the other being the 1907 season. Due to lack of satellite imagery or a reconnaissance aircraft, it is possible that there were two undetected storms in the Atlantic; both were declared extratropical.

Seasonal activity

The 1914 season produced one tropical storm that persisted from September 14–19, 1914, making it the least active Atlantic hurricane season on record. Only one storm formed in the year; two other possible tropical storms persisted but were later classified as extratropical.

Storms

Tropical Storm One

A tropical wave was indicated off the Florida coast on September 13 by Historical Weather Maps and the International Comprehensive Ocean-Atmosphere Data Set Project, though no gale-force winds were reported. The system organized, and formed to the east of the Florida coast as a tropical storm on September 14. It slowly tracked westward, and reached its peak intensity of 70 mph (110 km/h) on September 17, with a minimal pressure of 1004 mbar. Soon after reaching its peak intensity, the storm made landfall in Georgia on September 17, and tracked westward through the Gulf Coast region of the United States. The storm weakened over land as it tracked west-southwestward and dissipated over Louisiana and Texas at around 1200 UTC of September 19. COADS reported that Tropical Storm One had dissipated on September 20 while over land.

Winds over the South Atlantic coast were at gale-force, with some higher wind gusts off the Georgia coast. The storm produced rain throughout the southeast Atlantic and Gulf Coast states. Miami, Florida reported rainfall of 1/8 of an inch, and Cape Canaveral reported rainfalls of over ½ inch on September 16. On Wednesday, September 16, The Miami Herald reported that tides were high enough to flood the South Street Causeway near St. Augustine, Florida. Many dead grasses and marshes were blown throughout the city of Miami. No severe damage was reported in the area as a result of prior warnings to boatmen, and to coastal areas.

The storm caused unknown damage outside of St. Augustine, Florida, and there were no reported fatalities.

Other storms

The first of the two possible storms began as a baroclinic low, which formed in the Gulf of Mexico on September 28. The next day, a possible low-level center was forming and winds were reported of about 45 mph (70 km/h) from Pensacola. The storm disappeared on October 2 over land. The storm kept its baroclinic characteristics, classifying it as an extratropical storm.

A second tropical storm may have formed on October 24 in the western Gulf of Mexico. Historical Weather Maps and Comprehensive Ocean-Atmosphere Data Set indicated that it may have been a separate center from a possible nearby tropical depression. The lowest pressure in the system found was 1004 mbar, but the peak winds were only 25 mph (40 km/h) due to lack of low pressure. On October 27, it degenerated into a tropical low pressure area off the Carolinas. Overall it remained extratropical.

Accumulated cyclone energy

ACE (10⁴ kt²) – Storm: Accumulated cyclone energy/Atlantic by year
1	2.53	Tropical Storm One
Total=2.53

This season had the lowest ACE rating ever recorded. The only storm this season had an ACE of 2.53. The ACE is, broadly speaking, a measure of the power of the hurricane, multiplied by the length of time it existed for. However, it is possible that there could have been other short lived storms in the Atlantic hurricane season.
