What Tropical Storm Barry means for the Tennessee Valley
As TS Barry continues to strengthen today, the newest forecast shows Barry becoming a Hurricane tonight, and making landfall near Marsh Island, Louisiana Saturday between 2AM and 8AM EDT. What this means for the Tennessee Valley, is rain chances increase, along with thunderstorms. The track will play a large factor in the coming days. Once Barry makes landfall on Saturday morning, significant weakening is expected.
Barry looks to become a remnant low depression by Sunday morning. This means the maximum sustained surface winds will be under 39 mph at this point. Depending on the track, there is a chance the winds will be increasing over the Tennessee Valley from Monday through Wednesday of next week, especially for those that live on the higher elevations. I don't see much of an issue as far as wind is concerned for Chattanooga, but those that live on Signal Mountain, Lookout Mountain, and near Altamont and Monteagle could get sustained winds increasing next week. Again the track will play a large factor.
What we do know, are several waves of energy will continue to lift to the area through next Wednesday. Localized flooding from torrential rainfall is likely starting today (Friday) through next week. Rainfall amounts of 2" to 4" is possible from today through Wednesday too. The good news is the rainfall is bringing much-needed rain to many of our farmers. Since the unofficial start to summer on June 1, it's now 1" above normal, and 13" above normal since January 1st.
