When its central pressure fell to 929 mbar and its sustained winds reached 160 mph (260 km/h) on July 16, Emily became the strongest hurricane ever to form before August, breaking a record set by Hurricane Dennis just six days before. It was also the earliest Category 5 hurricane ever recorded in the Atlantic basin (beating Hurricane Allen's old record by nearly three weeks) and the only Category 5 hurricane ever recorded before August.
The intensification trend picked up again the next day with a fairly rapid drop in the storm's central pressure as it entered the southeastern Caribbean Sea, a region typically unfavorable for intensification. Hurricane Emily's winds increased in reaction, briefly bringing the storm to Category 4 strength early on July 15. During the day, the storm's strength fluctuated greatly, dropping to a Category 2 storm and then rebuilding to Category 4. On July 16, Emily strengthened considerably, making it the strongest hurricane ever on record to form in the month of July with peak winds of 160 mph (260 km/h), the earliest Category 5 in the Atlantic basin. Initially at this point Emily was thought to have peaked as a Category 4 storm, but the post-storm analysis showed it was indeed a Category 5 storm. The storm weakened slightly as it continued westward, and remained a Category 4 while passing south of Jamaica and, on July 17, the Cayman Islands. Hurricane Emily continued on its nearly straight track to the west-northwest, weakening somewhat but remaining at Category 4 until striking Cozumel just before mainland landfall at Playa del Carmen at 2:30 am EDT on July 18. Sustained winds were 135 mph (215 km/h), and the eyewall passed directly over Cozumel.
The center of circulation emerged over the Gulf of Mexico later that morning. Passage over land disrupted the hurricane's center of circulation, and it had weakened to a minimal hurricane with wind speeds of 75 mph (120 km/h). However, several hours over the warm waters of the western Gulf provided the energy needed for Emily to regenerate, and by midnight wind speeds were increasing. The increase in wind speed stalled, but the storm continued to become better organized. Emily started to show very symmetrical outflow, but the hurricane's strongest winds were being found at three different distances from the center. However, the outer wind radii subsided in the end, and the inner core prevailed. The result was a rapid strengthening of the inner core on the evening of the 19th. The pressure dropped about 30 millibars and the winds went from 90 mph (145 km/h) to more than 125 mph (200 km/h), all within a few hours.
Further strengthening was expected by forecasters, but did not come. The storm's motion slowed, and the center began wobbling erratically toward the coast. The storm made landfall around 6:00 am CDT (1100 UTC) on July 20 near San Fernando in Tamaulipas. The storm had sustained winds of 125 mph (200 km/h), Category 3 on the Saffir-Simpson Hurricane Scale. After heading inland over northeast Mexico, it dissipated over the Sierra Madre Oriental on July 21.
Landslides were reported in eastern Jamaica, triggered by heavy rain as the storm passed south of the island. Four people were reported dead. Damage was also reported in Trinidad and Tobago, where landslides and flooding damaged several homes.In all, ten people died across the Caribbean.
Emily caused havoc for Yucatán's tourism industry. Many hotels sustained significant damage, especially those built in a traditional style with thatched roofs. While Cancún remained relatively unscathed, further down the coast some hotels remained closed for many months, some reopening shortly before Hurricane Wilma hit; others having their re-openings delayed even further.
Emily's second landfall as a strong Category 3 hurricane brought significant damage to the northeast coast of Mexico. In the fishing community of Laguna Madre, over 80% of the buildings were destroyed as a result of the storm surge. Several communities on the remote coast of Tamaulipas were isolated after the storm, and major coastal flooding was reported along with heavy wind damage, with numerous homes destroyed. Inland flooding was also reported in Monterrey.
Communication to the Riviera Maya area was difficult after the storm; not all cellular phones were receiving coverage to the area, land lines were down, and electricity was out. About 18,000 people in 20 low-lying communities in the state of Tamaulipas, just south of the U.S.-Mexican border, were evacuated. Insured damages in Mexico were estimated at $200 million. The total damage estimate for Emily in Mexico was $400 million.
In the southernmost tip of Texas, damage was relatively minor despite the close proximity of the storm. No significant structural damage was reported, although some trees were down and over 30,000 customers lost electricity. Eight tornadoes were also reported in Texas as a result of Emily, destroying several homes. Some positive effects were noted; the remains of Emily passed farther west into Texas and delivered some badly needed rainfall, helping relieve a drought. Damage in Texas was less than $50 million.
