The first named storm of the season in USA, Subtropical Storm Alberto made landfall near Laguna Beach in Florida on 28 May, with maximum sustained winds of 75 km/h.

The previous day the storm caused flooding in parts of Cuba, where local media say around 22,000 people have evacuated. Reservoir levels are precariously high in some provinces. Flooded roads in Cienfuegos province means that some communities have been isolated. Buildings in the city of Cienfuegos have collapsed after the heavy rain.

Meanwhile in the USA the storm has already claimed two lives. Two journalists reporting on the severe weather in North Carolina died when a tree fell on their vehicle.

After making landfall, Alberto has continued moving north-northwest, slightly weakening into a Subtropical Depression. The storm is forecast keep moving north-northwestward moving over Alabama on 29 May and Tennessee on 30 May, weakening further but with potential for heavy rain.

Early on 29 May, the National Hurricane Center said “Heavy rainfall will lead to a significant risk of flash flooding across the Florida Panhandle, much of Alabama and western Georgia overnight, spreading northward into northern Georgia, the western Carolinas and Tennessee today.”
