CLANTON – 1130 am May 27, 2018. Alberto will make landfall in the Florida panhandle by early afternoon, moving through the central portions of Alabama on Tuesday and into the Tennessee Valley by Tuesday night. A Tropical Storm Warning remains in effect today for the southern sections of inland Alabama today and a Flash Flood Watch is in effect through Tuesday afternoon for all except the western sections.
Wind and rain will be on the increase today. For areas over the southern half of the state, generally south of a Livingston – Clanton – Lafayette (West Point Lake) line, sustained winds of 15-25 mph will occur through tonight, with gusts up to 35 mph.
However, the biggest concern will be the potential for tremendous rainfall. The map below shows that for the eastern half of the state, widespread 3-6 inches will occur, with isolated amounts of 8 inches or higher. Much of the rain will fall through Tuesday, but even with the system exiting the state, deep atmospheric moisture resides over the state with scattered to numerous showers and thunderstorms on Wednesday.
These types of systems produce rain bands that are incredible rain producers. You can literally go from nothing to over an inch of rain in a few minutes, making driving conditions very dangerous.
Do not drive into water covered roads, especially at night. It only takes around 18 inches of water to make vehicles lose contact with the road, and if the water is moving, you can easily be swept away from the current.
