PHOTOS: Officials evacuate dozens by boat as flooding submerges Louisiana neighborhoods

Relentless rain caused severe flooding across the southern U.S., killing three and prompting dozens of evacuations.

Multiple Louisiana neighborhoods were left with devastating flooding, with some homes experiencing water levels as high as the roof. Gov. John Bel Edwards declared an emergency in 16 parishes across the state.

A subdivision in Haughton, Louisiana, about 15 miles east of Shreveport, was inundated on Wednesday. More than 20 homes were evacuated.

In the Fox Chase subdivision, another 40 homes were evacuated, according to local officials. Deputies used boats to remove people safely from their residences. In addition to home rescues, officials performed numerous high water rescues after motorists drove through flooded roadways.

Schools in the area were closed on Thursday.

The torrential rain also created chaotic travel across the state, washing away multiple roadways.

"The combination of a slow-moving storm system and a plethora of moisture from the Gulf of Mexico has allowed heavy rain to stream into the South Central states," AccuWeather Meteorologist Krissy Pydynowski said. "Where the rain has been persistent, extremely high totals have been recorded."

With storms expected to continue across the region, residents won't likely see a chance to get back into their homes in the immediate future.

Officials opened emergency shelters near the hardest-hit areas for those left stranded.
