SAVANNAH, GA (WTOC) - An area of low pressure in the far-western Caribbean has been upgraded to Sub-Tropical Storm Alberto.
Despite encountering storm wind shear, drier air and land interaction – all of which storms do not like – this area of low pressure has become more organized and is now producing 40 mph sustained winds.
The area of lowest pressure is just off the Yucatan coast and drifting eastward. A northward turn is expected over the next twenty-four hours.
Alberto will be pulled towards the Gulf Coast this weekend. Moisture rapidly spreads into Florida and the southeast, on the sub-tropical storm's eastern side, Saturday and Sunday.
If you have Memorial Day errands or activities, Saturday is the best day to get them done. Only scattered rain is forecast through Saturday evening.
Several waves of rain are likely across the Coastal Empire and Lowcountry Sunday and Monday.
Two to four inches of rain is forecast to fall in many communities between midday Sunday and Monday evening. Isolated amounts greater than 5 inches are possible; mainly well inland.
The risk of severe weather this weekend remains quite low. However, an isolated storm or two may produce gusty winds and rotate. The risk of isolated tornadoes is very low, but not quite zero.
We'll let you know on TV, in the WTOC Weather App and at wtoc.com if the forecast changes.
