...Heavy Rainfall and Flooding Possible Later This Week...

There will be a couple of chances for heavy rainfall to impact the Tennessee Valley this week, with the first occurring over Tuesday/Wednesday, and the next occurring Friday/Saturday. Rainfall totals with the Tuesday/Wednesday event may range from 1.5" to 3", with the highest totals occurring over Northwest Alabama.

The second chance for heavy rainfall arrives Friday as a cold front approaches the area from the West. Several disturbances will develop and move Northeast across the area, bringing rainfall totals of 1.5" to 4", again with the highest totals occurring over Northwest Alabama.

Assuming we receive 4-6" of rainfall (total) over the span of 5 days, flooding concerns will increase heading into the weekend. While much of the first round of rainfall may be absorbed, this may increase the runoff during the second event, and we`ll have to closely watch area creeks and rivers during this time.

Take the time now and know what to do when/if a flood warning is issued for your location. While life-threatening flash flooding is not anticipated, flooding is certainly possible. During the holiday season, a lot of people are traveling in areas and on roadways that they are not as familiar with. Be sure to check in with those traveling during this time and let them know of alternate routes to destinations. Turn Around, Don`t Drown!
