Marine Tropical Storm · Atlantic South

Hurricane Irma moved north near and parallel to the Florida west coast from the afternoon of September 10 through the morning of September 11. The large wind field of the hurricane brought a long duration of sustained tropical storm winds to the offshore waters with frequent gusts to hurricane force, especially within squalls. A Scripps buoy just east of Port Canaveral measured seas up to 17 feet and NOAA buoy 41009 located 20 miles offshore Port Canaveral measured seas of 20 to 25 feet. Similar seas likely occurred across the waters farther offshore the Volusia County coast.

Hurricane Irma moved northward over the western Florida peninsula and produced a long duration of sustained tropical storm force winds with frequent gusts to hurricane force over the Atlantic coastal waters due to its very expansive wind field. These winds drove seas of at least 20 to 25 feet.
