Miami, May 25 (RHC)-- The first named storm of the 2018 Atlantic hurricane season has formed, according to the U.S. National Hurricane Center in Miami.

Subtropical Storm Alberto developed Friday morning and was located about 55 miles south of Cozumel, Mexico. It has winds of 40 mph and was moving to the north-northeast at 6 mph.

"Alberto could bring tropical storm conditions and storm surge to portions of the central and eastern U.S. Gulf Coast later this weekend and early next week," the hurricane center said. Alberto is forecast to approach the north-central Gulf Coast on Monday.

The slow-moving storm will also dump heavy rain across much of the southeastern United States over the weekend.

The storm is forecast to bring between six and 12 inches of rain to the Northwest Florida area, and there is the possibility of 12 to 24 inches of rain in some areas.
