Isaias was downgraded Sunday from a hurricane to a tropical storm but is still expected to wreak havoc on Florida's east coast with sustained winds of 65 mph and gusts of 75 mph.

The National Hurricane Center reports that as of 11 a.m. ET Sunday, Isaias was about 55 miles southeast of Fort Pierce in Central Florida and was moving northwest at just 8 mph. Fort Pierce is roughly 130 miles north of Miami.

"Tropical storm conditions will spread northward along the east coast of Florida within the warning area through early Monday and will reach the coasts of Georgia, South Carolina and southern North Carolina within the warning area Monday and early Tuesday," the National Hurricane Center reported Sunday morning.

Parts of Florida could see as much as six inches of rain. Coastal Georgia will see up to three inches of rain.

Heavy rain is forecasted throughout the East Coast this week and could reach as high as Maine.

The National Hurricane Center said: "Flash and urban flooding, some of which may be significant in the coastal Carolinas and Virginia, is expected through midweek along and near the path of Isaias along the U.S. East Coast."

Isaias comes as Florida deals with a surge in coronavirus cases. Florida's Division of Emergency Management has created protective equipment reserves for the storm season of 20 million masks and 10 million gowns.

As a hurricane, Isaias caused extensive damage Thursday to Puerto Rico and the Dominican Republic before striking the Bahamas and Turks and Caicos on Friday.
