The last data received from a previous Air Force Reserve reconnaissance aircraft, along with recent satellite and radar imagery, indicate that Isaias has weakened to a tropical storm due to a combination of shear, dry air and interaction with Andros Island earlier today. But it could re-strengthen into a hurricane.
Here's what you need to know:
Hurricane conditions are expected along portions of the Florida east coast on Sunday with tropical storm conditions expected to begin tonight. Preparations to protect life and property should be rushed to completion.
Dangerous storm surge is possible along the Florida east coast from Jupiter Inlet to Ponte Vedra Beach where water rises of 2 to 4 feet above ground level are possible along the immediate coastline and adjacent waterways. Residents there should follow advice given by local emergency officials.
Tropical storm watches and warnings are in effect for portions of the United States East Coast from northeast Florida to South Carolina. Additional watches and warnings will likely be issued tonight and Sunday as Isaias is expected to move northward near or over the southeast and mid-Atlantic coasts early next week.
