Areal Flood Watch Issued

Posted on: 4:23 am, May 3, 2013, by

You might ask what’s the difference between an “areal” flood watch and a flood watch? An areal flood watch means the flood encompasses a larger area. As you can see, all of the WHNT News 19 viewing audience, most of Tennessee, and north Georgia are under this watch until Saturday at 7pm. This will likely be expanded and extended through the weekend.

The main upper level disturbance still remains to our west, but once it moves over the area, rain and cooler temperatures are expected. Highs over the weekend may not get out of the 50s and 60s. Only a few showers are possible this morning, but heavy rain moves in late this afternoon through tonight and early Saturday. There is a chance of a “dry slot” around our storm Saturday. If you are in the Shoals, mainly west of I-65, you could get a break in the rain Saturday afternoon. For those in eastern sections, the rain is likely to hold on a little longer. By Sunday, the main low pressure passes over returning all of the Tennessee Valley to rainy weather.

Here is the forecast map for Saturday at noon.

The lighter shade of blue indicates cooler temperatures. That’s why highs likely struggle this weekend.

Here are your rainfall totals through Monday morning. All of the Tennessee Valley will see at least an inch or two of rain. Areas across the northern Cumberland Plateau, DeKalb County, and Jackson Counties could receive over 3″ of rain leading to flash flooding. Keep that in mind if you have travel plans this weekend. Don’t ever cross where water covers the road.

The bright red and orange indicate 3 inches of rain or more!
