4WARN Weather Alert: FLOOD THREAT

A 4WARN Weather Alert’s in effect due to the threat for flooding.  Rain will come in waves over the next two days.  It won’t rain the whole time, but when it does, occasionally it’ll be heavy.  The heaviest rain and the best chance for thunderstorms will occur over southern Middle Tennessee.  Severe weather looks unlikely, although a few strong storms may approach southern Middle Tennessee tomorrow afternoon and tomorrow evening from the south.

A Flood Watch has been issued for most of our area from noon Wednesday through noon Thursday.

Heavy rain’s now moving into West Tennessee, approaching Middle Tennessee.  Light rain’s already developing around Nashville, as seen on 4WARN Live Doppler Radar.

FUTURECAST shows how this system will take shape.  The heaviest rain will fall tomorrow night.  Therefore the best chance of flooding will be then through Thursday.  Rivers will rise well into next week in many cases, however.

Rain totals from this system will be very impressive!  1-2″ are likely along the I-40 corridor with lesser amounts farther north.  3-6″ appear likely over southern Middle Tennessee.

Several flood advisories, watches, and warnings are in effect.  Two stand out to me right now.

The first is the Flood Advisory for the Cumberland River at Clarksville.  By Friday afternoon, the river will approach flood stage.  Water will approach several industrial and commercial businesses along the river.

A Flood Watch has been issued for the Buffalo River at Lobelville.  On Friday, as the river reaches 16 feet, Route 438 south of Lobelville will become impassable.  Remember, turn around.  Don’t drown.  Plan on taking an alternate route.

Be sure to watch Melanie Layden on News4 Today in the morning.  She’ll have the latest view of the heaviest downpours on 4WARN Live Doppler Radar.
