... Flash Flood Watch now in effect until 9 PM CST this evening...
The Flash Flood Watch is now in effect for
* portions of southeast Louisiana and southern Mississippi... including the following areas... in southeast Louisiana... Ascension... Assumption... East Baton Rouge... East Feliciana... Iberville... Livingston... lower St. Bernard... Orleans... Pointe Coupee... St. Charles... St. Helena... St. James... St. John The Baptist... St. Tammany... Tangipahoa... upper Jefferson... upper Lafourche... upper Plaquemines... upper St. Bernard... upper Terrebonne... Washington... West Baton Rouge and West Feliciana. In southern Mississippi... Amite... Hancock... Harrison... Jackson... Pearl River... Pike... Walthall and Wilkinson.
* Until 9 PM CST this evening
* a upper level disturbance will move through the central Gulf Coast region this evening while a cold front approaches. Very moist air in place will interact with the disturbance to produce additional heavy rain across most of southeast Louisiana and south Mississippi. Many areas are quite saturated from the heavy rainfall early this morning and last evening... so it will not take much heavy rainfall to produce areas of flooding today. The heaviest rain should occur through the late afternoon and evening hours.
* Widespread additional heavy rainfall amounts of 1 to 2 inches are expected with localized heavier amounts of 3 inches possible. This will result in areas of street flooding... possible flooding of canals and small streams... and potentially more serious flooding of property.
Precautionary/preparedness actions...
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
