The main concern will be heavy rain over the Southeast and Florida. Rip currents, coastal flooding, winds, and tornadoes are expected. Tropical storm watches have been issued for the western Cuba province of Pinar del Río and also for a part of Mexico’s Yucatán Peninsula from Tulúm to Cabo Catoche, including Cancún and Cozumel. Alberto is expected to track north into the Gulf of Mexico by Saturday. It will become a fully tropical storm in the Gulf of Mexico later this weekend.
Flood watches are already in effect for parts of the Southeast, lasting from Saturday evening through Tuesday along parts of northern Gulf Coast. In most areas away from the Gulf Coast in Alabama, Georgia and the Carolinas, 3-hour rainfall of 3 inches or less would trigger flash flooding, according to the National Weather Service. Winds will produce increasingly higher surf along the northern and eastern Gulf Coast from southeast Louisiana to western Florida beginning as soon as Saturday. The potential for flooding will increase early next week. Coastal flooding or some normally dry areas can also be expected from southeast Louisiana to Florida’s Gulf Coast particularly Sunday and Monday.
