A low pressure system is expected to lift north of the area for Wednesday. A trailing cold front will extend southward from the low and position west of the area through Wednesday. Ahead of the cold front, a strong return flow from the gulf will increase moisture and the chances for rain. The latest forecast guidance suggest anywhere between 2-3” of rain is possible.
Given the saturated soils from previous heavy rains… flooding and flash flooding will be possible. Be advised that flooding conditions will likely occur on the Sequatchie River and its tributaries. With low flash flood guidance, the Little Sequatchie River may also flood due to already high river levels. Please do NOT drive into flooded roadways. Do NOT allow your children to play in and around standing flood water.
The National Weather Service has issued a Flood Watch through Wednesday evening. Remember the National Weather Service’s slogan… Turn around… Don’t drown.
