The Carolinas and Mid-Atlantic states are bracing for Hurricane Florence, a Category 4 storm which is teetering on becoming stronger before landfall later this week.
Florence will have a minimal impact on the D.C. Metro Area. Damaging winds, floods, high surf and storm surge are still possible.
"Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana on Friday and Saturday", the hurricane center said.
The Met Office has claimed Helene, which is now making its way through the Atlantic, could bring temperatures as high as 26C in the London area, while reaching only 6C in Scotland. "This storm is extremely unsafe". It was moving to the west at 16 miles per hour with maximum sustained winds of 35 miles per hour.
Florence, however, continues to threaten the east coast as a fierce storm that could trigger flooding as far south as Georgia.
At 500 a.m. AST (0900 UTC), the center of Subtropical Storm Joyce was located near latitude 33.8 north, longitude 43.1 west.
"As long as it seems there is a threat to lives, we want to make sure people are safe", Shaw said.

There were two other systems in development Wednesday as well.
Around six o'clock this morning, the center of Isaac passed 150 miles to the north of Barbados.
The storm is now around 530 miles southeast of Cape Fear, North Carolina, and is moving west-northwest at 17 mph. Earlier forecasts showed that the storm was slated to directly hit around North and SC.
Residents on the Carolina coast are finding empty gas pumps and depleted store shelves as they flee a potentially devastating blow from Hurricane Florence.
A tropical storm warning means that tropical storm conditions are expected somewhere in the warning area within 36 hours, and a watch within 48 hours.
