Subtropical Storm Alberto — the first named storm of the 2018 hurricane season — was continued roiling toward parts of coastal Mexico and Cuba with rip currents and dangerous surf on Saturday. Both countries issued tropical storm watches for portions of their coastlines, with rain totals in some isolated areas of up to 25 inches.
U.S. forecasters followed suit by issuing a tropical storm watch for parts of the Gulf Coast from the Florida Panhandle southwest of Tallahassee to the New Orleans metropolitan area.

Its top sustained winds were 40 mph (65 kph). A gradual strengthening was expected through the weekend as it moves north.
