Flash Flood Watch Issued For Much Of The Viewing Area

By: Stephen Crews
Updated: February 21, 2013
A flash flood watch has been issued for much of the viewing area.

An active weather pattern was developing across the Gulf Coast, with a series of storm systems forecast to move across the southeastern U.S.

The first storm was taking shape over the Southern Plains, and will impact the region Friday and Saturday. The second system was southwest of Alaska, and will reach the Deep South early next week.

While there may be a slight risk of severe storms with each of these storm systems, the primary threat appears to be the potential for very heavy rainfall, and subsequent Flash Flooding and river flooding, as each of these systems taps a very warm and moist airmass over the Gulf of Mexico.

The greatest threat for flash flooding appears to be in Southeast Alabama and Southwest 
Georgia, but there is also some risk for the Florida Panhandle as well, especially as (if) the 
heavy rain bands shifts slowly southward Friday night and Saturday.

The timing will likely be from Friday afternoon through Saturday morning. The threat of river 
flooding will increase through the weekend and last through next week, as heavy rain from 
swollen upstream rivers flows downstream.

Summary
  • Heavy rain is expected Friday and Saturday, posing a risk for flash flooding
  • Whether this heavy rain occurs in our area or just to our north, there will likely be significant rises in our local rivers this weekend and next week, as upstream heavy rain moves quickly downstream
  • If there is an additional bout of heavy rain early next week, that would obviously increase  the threat of flash flooding and river flooding even more
  • There is a slight risk of severe storms Friday, but at this time that appears to be the lesser  threat (compared to the overall flooding threat)
