As of 10 PM CDT…Tropical Storm Isaias remains a strong tropical storm with maximum sustained winds of 70 mph, moving NW at 9 mph with a minimum central pressure of 995mb–up 2mb from the previous advisory. The storm has become much less organized due to a combination of dry air & wind shear. However, the impacts for Florida remain largely unchanged from previous forecasts.
Regardless of this weakening trend, the storm is still expected to brush along the East coast of Florida as a strong tropical storm or category 1 hurricane, tracking parallel to the shore & producing heavy rain, strong winds, coastal erosion, & storm surge. Hurricane Warnings currently extend from Biscayne Bay to Jacksonville Beach as the storm rides along the coast, & Tropical Storm Warnings are in effect for cities farther inland, including but not limited to Fort Lauderdale, Orlando, & Jacksonville. This path is very similar to what Hurricane Matthew & Hurricane Dorian did in both 2016 & 2019 respectively.
NO impacts expected from this storm for Central Alabama.
Hurricane conditions & dangerous storm surge will continue in portions of the Northwest Bahamas tonight. Hurricane conditions are expected along the Florida East coast on Sunday, with tropical storm conditions beginning tonight for a large portion of Southeast Florida.
Dangerous storm surge is possible from Jupiter Inlet to Ponte Vedra Beach, where water rises of 2 to 4 feet of storm surge are possible along the immediate coastline & adjacent waterways. Residents there should follow advice from local emergency officials.
Tropical Storm Watches & Warnings are in effect for portions of the United States East Coast from Northeast Florida to South Carolina. Additional Watches & Warnings will likely be issued tonight as Isaias is expected to move Northward near the Southeast mid-Atlantic states Monday & Tuesday.
