Heavy rain and thunderstorms have been the main story this morning as we have a mass of storms continuing to work through the northwestern and northern parts of Central Alabama and the west and central parts of North Alabama. These heavy rains have caused flooding issues in the western parts of North Alabama as Flash Flood Warnings are currently in effect for parts of Lauderdale, Colbert, Franklin, and Lawrence counties. We have some flooding issues in the northwestern parts of Central Alabama as well.
The National Weather Service in Birmingham has issued a Small Stream Flood Advisory for Poor Drainage Areas in Northern Marion County until 11:00 am. Overflowing poor drainage areas will result in minor flooding in the advisory area. Up to two inches of rain have already fallen according to radar estimates. Some locations that will experience flooding include Hamilton, Haleyville, Hackleburg, Brinn, Bear Creek, Tessner, Bexar, Pigeye, Shottsville, and Upper Bear Creek Reservoir.
Throughout the rest of the morning, localized flash flooding issues will be possible across the extreme northwestern and northern parts of Central Alabama as this mass of storms continue to move slowly eastward. Conditions are favorable for some back building to occur on the west side of this mass of storms and could potentially bring more heavy rains to locations that have already seen copious amounts of rainfall this morning.
With the precipitable water values up to and in excess of 2 inches, significant rain rates of 2 inches per hour or higher will be possible, which may lead to more localized flash flooding issues where this back building can occur.
Additional convective development is expected across western Tennessee and northern Mississippi by the early afternoon hours, and this could combine with the current activity to produce additional training of cells and the potential of more flash flooding issues.
