KATC StormTeam 3 Weather BLOG

Rain and embedded thunderstorms continue to slowly march eastward this evening.  Activity across western portions of Acadiana has been dropping about 2″ or rain in less than an hour’s time resulting in localized street flooding across Calcasieu and more than likely Jeff Davis Parish as of 615pm this evening.  Rainfall totals of 2-3″ will be likely area-wide and as Dave mentioned there may be some hots spots along the coast that catch 3-5″.  With all the wet weather of late the ground has become and stayed quite saturated so it will only take a little more than an 1-2″ of rain in a short period of time to cause some run-off problems.  Weak cyclogenesis (low pressure development) is occurring along the Southwest Louisiana coast this evening with this low expected to sweep east-northeastward across the coastal parishes and over SE Louisiana tomorrow morning.  It does appear that the greatest risk of severe weather should stay offshore but some rotating cells may be possible along the coastal parishes (in the warm sector of the low) and over extreme SE Louisiana tomorrow morning.  Nonetheless we’ll still be on the lookout for trouble-makers overnight but right now it looks mostly like a flood threat through tomorrow morning with the severe weather parameters staying elevated across the area.   After a very wet morning, rain showers will become more scattered in nature for Tuesday afternoon with clearing and cooler conditions anticipated for Tuesday night.  We’ll get a nice break on Wednesday with mostly sunny and pleasant conditions expected but the next storm system promises another, perhaps a greater threat, of flooding rains, and a better shot at severe weather for Thursday possibly into Friday.  Rain and storms could move back into the area as early as late Wednesday night with severe weather/tornado  risks possible beginning by Thursday morning…so stay tuned.  At least there is some good news…the weekend will be dry and pleasant…so Halloween should be a treat!
