Detailed Look at Central Alabama Impacts From Alberto

| May 28, 2018 @ 12:30 pm

Subtropical Storm Alberto is nearing a landfall on the Florida coast near Panama City at this hour.

The center will begin to weaken as it moves inland this afternoon. Heavier rain will start spreading into South Alabama after noon and will reach Troy and Greenville by 4 pm or so.

Some storms will likely form along the leading edge of the rain shield as it encounters decent instability in the I-85 Corridor. We will have to watch for the potential for a few isolated spin-up tornadoes from Auburn through Troy, Union Springs, and Eufaula later this afternoon.

Winds of 15-25 mph with gusts to 35-40 mph will spread into South and Southeast Alabama after 2 p.m. A tropical storm warning is in effect for Southeast Alabama Counties.
