The National Weather Service has issued a flash-flood watch, beginning at 6 p.m. Sunday and running into Monday morning, for southeast Louisiana, southwest and coastal Mississippi and southern Alabama.
The Mississippi Coast could see 2 to 4 inches of rain, with higher amounts in some areas, Harrison County Emergency Manager Rupert Lacy said in an email alert. He said the possibility exists for weak tornadoes.
“It appears that this will be a relatively low-impact event compared to other heavy rain events we’ve had,” Lacy wrote. “However, the potential for flash flooding tonight and Monday morning is enough to warrant a watch.
“If any tornado develops, it’s more likely to happen south of a line from Baton Rouge to Slidell or the Mississippi Coast.”
A chance of showers will continue through Monday night, the NWS says, with temperatures climbing to 69 degrees by Tuesday night and lows forecast in the 50s.
