Tropical storm watches and warnings now stretch from Florida to North Carolina's Outer Banks as Tropical Storm Isaias hovers off the Florida coast.
The storm is expected to make its way up the East Coast after bringing downpours and gusty winds to the Florida Peninsula Sunday afternoon and evening.
Isaias could unleash six inches of rain to parts of eastern Florida and a storm surge of 1 to 4 feet.
In St. Lucie County, officials on Sunday urged residents to avoid the beaches for several days due to rough surf and rip currents. Officials said they're also concerned about power outages.
By Monday morning, Isaias will be moving just off the northeast coast of Florida.
Isaias will then pick up speed, racing up the East Coast.
On Monday and Monday night, the Carolinas may see up to six inches of rain.
North Carolina Gov. Roy Cooper said he's activated up to 150 National Guard soldiers to help with the storm.
"The forecast has the storm moving quickly, which we hope means the rain and wind won't last as long," he tweeted Sunday afternoon. "But a lot of rain is expected to fall at once, so be on alert for flash flooding and river flooding."
Widespread power outages should be expected, the governor added.
Isaias will gradually weaken as it moves north.
On Tuesday and Tuesday night, Isaias will bring heavy rain to much of the Northeast, from Washington, DC, to Philadelphia to New York City.
Parts of the mid-Atlantic could see four to six inches of rain, likely triggering flash flooding.
