Hermine formed in the Florida Straits south of Key West on August 28th. It remained a very disorganized tropical depression for a few days before the environment around it gradually became more favorable and it became a tropical storm late in the day on the 30th. Hurricane Hermine made landfall just east of St. Marks, Florida around 0130EDT on September 2 as a Category 1 Hurricane with a minimum central pressure of 982 mb, and maximum sustained winds estimated at 70 knots (80 MPH). Heavy rainfall over West-Central and Southwest Florida began on August 31 and continued through September 2, with as much as 20 inches of rain falling in some locations. River flooding from this heavy rain impacted some areas through September 6th. Storm surge generally ranged from 2 to 7 feet above normal high tide, with the highest storm surge value recorded of 7.5 feet at Cedar Key.

The collective effects of Hurricane Hermine during the period of September 1-6 resulted in just over $219M in property damage, and no fatalities or injuries across West-Central and Southwest Florida.
