The Huntsville weather office has issued a Flash Flood Watch for the Tennessee Valley region of North Alabama from Sunday evening through Monday afternoon.
A potent storm system out of the Western Gulf Coast will lift to the northeast today. Thunderstorms will gradually overspread north Alabama during the afternoon and evening hours.
The prime time for the rain in the Tennessee Valley will be tonight and into Monday with the potential of heavy rainfall. 2 to 4 inches of rain with locally heavier amounts will be possible by Monday afternoon.
The heavier rainfall amounts are expected to be east of Interstate 65. The rain will begin to taper off from west to east by Monday afternoon.
Though conditions have been dry so far this year, this amount of rainfall may cause flooding issues across the area. This is especially the case for locations east of Interstate 65 where the heavier rainfall amounts are expected. Areas with poor drainage and locations in low-lying areas will be most susceptible to flooding concerns.
Some of these storms may become strong to marginally severe late tonight into early Monday. The storms will be capable of damaging winds, heavy rainfall, and possibly brief tornadoes.
