Hurricane Center increases tropical development chance to 90 percent

The 1 p.m. update on Subtropical Storm Alberto from the National Hurricane Center says the story is still almost stationary.

Typically water temperatures need to be at least 80 degrees for a tropical storm to form.

This Memorial Day weekend, anyone seeking nice weather should avoid South Florida and the Gulf Coast.

The first named storm of the 2018 Atlantic hurricane season has formed, the National Hurricane Center said.

These rains could produce life-threatening flash floods and mudslides.

A hurricane center map shows Alberto approaching the Gulf Coast on Monday, somewhere between Louisiana and the Florida Panhandle. "A Tropical Storm Watch means that tropical storm conditions are possible in the United States portion of that watch area within 48 hours".

A visible satellite image of the cluster of thunderstorms forecasters are watching for signs of tropical storm development.

The special notice warns a front of low pressure has formed over the Yucatan Peninsula in Mexico and threatens to push north towards Florida.

Today, no tropical impact.

The system sits east of the Yucatan Peninsula but moving northward. Alberto is centered about 55 miles south of Cozumel, Mexico and moving NNE at 6 mph.

An Air Force Reserve reconnaissance aircraft is scheduled to investigate the low this afternoon. The conditions are expected to spread to the eastern and central Gulf Coast later this weekend.

Torrential rain, flooding and thunderstorms are likely across the Caribbean, the Gulf states and southern U.S. states even if a tropical storm does not materialise. For more information on the heavy rain threat, please see products issued by your local weather office.

"Its mostly looking like a heavy rain event", National Weather Service meteorologist John McMichael said. "Extreme" flood watches have already been issued beginning Saturday for counties from Mobile to Okaloosa.

The National Weather Service said there was a 90 percent chance of it becoming a subtropical or tropical cyclone in the Gulf by the weekend.

Tropical Storm Alberto will bring rain to North Carolina over the Memorial Day weekend, but it appears the worst of it will hold off until Sunday night through Monday.
