![]() ![]() The system maintained its strength as it moved west over Florida, but the NHC noted that a strong convective burst near the center of the cyclone had weakened considerably. Just after 06:00 UTC on September 12, the depression made landfall near Cutler Bay, Florida, with winds of 35 mph (56 km/h) and a pressure of 1,003 mbar (29.6 inHg). At 18:00 UTC, the system had organized enough to be designated as Tropical Depression Nineteen. ![]() Over the next two days, convection rapidly increased, became better organized, and formed a broad area of low-pressure on September 11. At 00:00 UTC on September 10, the NHC began to monitor the area of disturbed weather as it was over the Bahamas for possible development. Omar dissipated the next day and its remnants move northeastward while the trough moved slowly south-southwestward over the Western Atlantic over the next several days, showing little to no signs of organization. On September 4, a surface trough formed on the south and southwest side of then- Tropical Depression Omar near Bermuda. Meteorological history Map plotting the storm's track and intensity, according to the Saffir–Simpson scaleĮxtratropical cyclone, remnant low, tropical disturbance, or monsoon depression Despite the destruction caused by the storm, the name Sally was not retired during the following year making Sally the costliest tropical cyclone in the North Atlantic on record that did not have its name retired. Damage is estimated at $7.3 billion (2020 USD). Numerous tornadoes also occurred as well. The area between Mobile, Alabama, and Pensacola - Gulf Breeze, Florida took the brunt of the storm with widespread wind damage, storm surge flooding, and over 20 inches (510 mm) of rainfall in the first 24 hours and over 30 inches in 48 hours. In South Florida, heavy rain led to localized flash flooding while the rest of peninsula saw continuous shower and thunderstorm activity due to asymmetric structure of Sally. Numerous watches and warnings were issued in anticipation of the imminent approach of Sally and several coastline counties and parishes on the Gulf Coast were evacuated. Sally's remnants lasted for another day as they moved off the coast of the Southeastern United States, before being absorbed into another extratropical storm on September 18. The storm rapidly weakened after landfall, before transitioning into an extratropical low at 12:00 UTC the next day. Despite this increase in wind shear, it unexpectedly re-intensified, reaching Category 2 status early on September 16, before making landfall at peak intensity at 09:45 UTC on September 16, near Gulf Shores, Alabama, with maximum sustained winds of 110 mph (180 km/h) and a minimum central pressure of 965 millibars (28.5 inHg). However, an increase in wind shear and upwelling of colder waters halted the intensification and Sally weakened slightly on September 15 before turning slowly northeastward. ![]() On September 14, a center reformation into the center of the convection occurred, and data from a hurricane hunter reconnaissance aircraft showed that Sally rapidly intensified into a strong Category 1 hurricane. Moderate northwesterly shear prevented significant intensification for the first two days, but convection continued to grow towards the center and Sally slowly intensified. Early the next day, the depression made landfall at Key Biscayne, and subsequently strengthened into Tropical Storm Sally that afternoon. The system grew a broad area of low-pressure on September 11, and was designated as a tropical depression late that day. The eighteenth named storm, and seventh hurricane of the extremely active 2020 Atlantic hurricane season, Sally developed from an area of disturbed weather which was first monitored over the Bahamas on September 10. state of Alabama since Ivan in 2004, coincidentally on the same date in the same place. Hurricane Sally was a destructive and slow-moving Atlantic hurricane, which was the first hurricane to make landfall in the U.S. Part of the 2020 Atlantic hurricane season Hurricane Sally rapidly intensifying before landfall in Alabama on September 16 ![]()
