Residents in southern Mississippi experienced a flash flood emergency on Thursday morning.
The towns of Biloxi and Gulfport, in particular, are slated to see upwards of 10 inches of floodwater, in addition to severe thunderstorms and possible waterspouts, according the the National Weather Service.
"Very bad weather currently," Gulfport police said in a statement on Facebook and Twitter. "If you don't have to be out in this mess, stay indoors. Numerous roadways and neighborhoods are flooded. Be careful."
Biloxi's assistant fire chief told the Weather Channel that this is the "worst flooding since Katrina" that the area has seen.
