Wider weather episode

A low pressure system, turned tropical disturbance, moving across the western Atlantic and over the Bahamas abruptly formed into Tropical Depression Nineteen on September 11th. Tropical Depression Nineteen gradually continued westward and the center passed about 10 to 20 miles SSE of Miami, Florida during the morning of September 12th with a minimum central pressure of 1007 mb and maximum sustained winds of 35 mph. As Tropical Depression Nineteen moved westward over the South Florida peninsula, it continued to strengthen into a Tropical Storm known as Tropical Storm Sally. Lowest surface pressure recorded over the South Florida Gulf Coast was 1002.9 mb at Naples Municipal Airport and maximum sustained winds of 31 mph at Marco Island Airport on September 12. Estimated Tropical Storm force sustained winds were measured across the Gulf waters ranging from 40 to 46 mph, with higher gusts.

Although the effects from Tropical Depression Nineteen were generally minor for wind, there were sustained Tropical Storm force winds over the Gulf waters which created hazardous marine conditions.
