Hurricane Sally - September 12-18, 2020
The tail end of a barolinic trough trailing Omar was south of Bermuda in
early September. It moved west-southwest
for several days developing disorganized showers and thunderstorms as it approached
the Bahamas on the 10th. Development ensued,
and a tropical depression formed between Andros and Bimini in the Bahamas on the
afternoon of the 11th. It turned west and
made landfall near Culter Bay during the early morning of the 12th. Strengthening
continued over land, and mid-morning, the
depression was upgraded to Tropical Storm Sally while centered west of Homestead.
Sally emerged over the Gulf of Mexico late
morning and turned northwest, but northwest vertical wind shear slowed strengthening.
Sally strengthened into a hurricane about
125 miles south of Pensacola on the 14th before moderate to strong wind shear
resumed. The hurricane slowed to a crawl
and turned northward on the 15th. Later that day, intensification resumed. Its
eyewall moved ashore Baldwin County, Alabama
that night, and the system continued to recurve northeast into the Florida Panhandle.
Moving back into southern Alabama, Sally regained
tropical storm status early in the afternoon of the 16th, tropical depression status
just south-southeast of Montgomery early on the
morning of the 17th, and then post-tropical/extratropical later that morning before
heading into Georgia. Accelerating east-northeast,
the system crossed the Carolinas before heading into the western subtropical north
