Dangerous flash flooding drenched the streets of metro New Orleans on Monday, impeding vehicular movement and knocking out power for thousands of residents.
Threatening conditions continued into Tuesday as storms meandered across the region.
NATIONAL WEATHER FORECAST: GULF COAST TO GET DRENCHED THIS WEEK
"A significant line of showers and thunderstorms is moving into metro NOLA. A flash flood warning is in effect for parts of the Westbank and additional warnings are possible, the National Weather Service New Orleans area tweeted Tuesday. "Please use extreme caution on area roadways!"
The agency's Weather Prediction Center said that a frontal boundary across the Gulf Coast states interacting with "moist inflow" from the Gulf of Mexico would create showers and thunderstorms, leading to the potential for scattered flash floods, a flash flood watch and a slight risk of excessive rainfall into Wednesday.
NOLA.com reported that forecasters said up to 6 inches of rain fell in some areas on Monday and videos and photos on social media showed trash and even an alligator moving through floodwaters.
