You’ve heard us talking about Harvey impacting the Gulf coast with catastrophic flooding and devastation as early as last weekend up through this entire week. Well now, Middle Tennessee gets a share of what is left over. Harvey has weakened to a Tropical Depression, currently stationed over northeastern Louisiana, headed northeast at about 10 mph with max sustained winds at 30 mph. The center of Harvey is expected to push through overnight tonight into the first half of Friday. PAUL TROPICAL FORECAST

Here’s what you need to know to stay prepared. We are expected numerous rounds of heavy rain, a potential for strong to severe storms and a likely chance of flash flooding, especially across western Middle Tennessee.WSMV CheckList_VIDEOInput

Latest forecast models push Harvey a bit further east, bringing more rain a bit further east than initially anticipated. Though widespread rainfall accumulations are expected to be around the 2-4″ range, local amounts could clock in at 8″ for areas under the bright shade of orange.DAPHNE ECMWF RAIN

The National Weather Service has expanded the Flash Flood Watch east, including the entire KY/TN border and most of our counties west of I-65 — in effect through 7 PM on Friday. These are the spots where flash flooding is most likely to occur.DD HEATWATCH2

As far as severe weather is concerned, the Storm Prediction Center includes areas south of the I-40 corridor to remain under a ‘Slight Risk’ for any storm to reach severe criteria. A few tornadoes later today is not out of question.DAPHNE SEVERE 2 RISK REGION BOX

Once we roll into tomorrow, the severe weather threat diminishes to a ‘Marginal Risk’ for areas east of I-65 (level 1 of 5). DAPHNE SEVERE 3 RISK REGION BOX
