It has been raining heavily in the central United States for the past week, flooding areas from Houston to Little Rock, Ark. This week, the same stormy weather is moving to the southeast.
Flash Flood warning Heavy thunderstorms were issued in the Little Rock area on Saturday night, causing roads to fill And almost covered bridge In the water across the subway. Within a few hours, more than an inch of rain fell in the city and other parts of the region.
To the south, a flood warning was in effect around the rivers of eastern Texas and western Louisiana. The storm’s target is forecast to gradually shift east this week, setting parts of the Southeast in its sights.
“The main driver over the next two days will be a slow-moving cold front that will travel across the region,” said AccuWeather meteorologist Alex DaSilva. It is likely to bring a very active pattern in terms of stormy weather.
New Orleans and Nashville, Tenn. As cities continue to receive rain and thunderstorms, the front tilt through the southeast, moving into places such as Montgomery, Alab., on Sunday. It may also rain in Atlanta late in the day or early Sunday. By Monday, thunderstorms are forecast to extend to the Carolinas, affecting Charlotte, NC and Tallahassee, Fla.
“Although not expected to be severe, these storms can still produce heavy rains that can lead to flash floods,” DaSilva said. According to the National Weather Service, flash floods occur within six hours of heavy or excessive rainfall.
Such an event is more likely to occur in places where soils are already saturated, such as New Orleans, which received 184 of the average rainfall for the entire month of September, when Hurricane Nicholas poured rain into the area. Even further north in Nashville, 118 of the average rainfall fell last month, and coastal cities like Charleston, SC had 121 of the average.
“By Tuesday, a dip in the jet stream over Arkansas and the Mississippi will help increase precipitation in the Southeast,” DaSilva said.
This dip is expected to help draw significant moisture from the Gulf of Mexico into the Southeast, which will result in further flooding concerns. As the regime of this humid air mass is in working condition over the entire area. A tropical feature forecast to develop off the southeast coast could also lead to increased storms, rain and humidity by mid-week, particularly from Florida to the Carolinas.
“By the end of the week, the dip in the jet stream will move northward into the Ohio Valley,” DaSilva said, explaining that this departure could allow the interior Southeast to dry up. Unfortunately for some, he said, coastal areas are still battling flooding from a nearby tropical disturbance.
Forecasters recommend that residents have a reliable way of receiving weather warnings and avoid going into their basements when the deluge strikes. According to the Federal Emergency Management Agency, six inches of water from flash flooding is enough to cause cars to lose control or stall. Motorists are warned never to drive on flooded roadways and, when in doubt, remember the slogan “Swirl, don’t drown”.
