Weekend Offers More Rain for Deep South

September 17, 2021
UPDATED By WeatherBug Meteorologists
After a week of heavy rain, more wet weather is set to soak weekend plans across the Gulf Coast and Deep South.

The cause for the continued rounds of heavy rain will be the remnants of what was once Hurricane Nicholas. Rainfall amounts related to this system have been mounting up and saturating soil from Texas to the Florida Panhandle this work week. Widespread totals of 5 to 10 inches of rain have been observed and there have been isolated amounts in excess of a foot. Now, heading into the weekend, more heavy downpours look to elevate the flood threat.

Due to the remnant low pressure system’s location parked over the lower Mississippi Valley, a moist, southerly flow is drawing plenty of moisture from the Gulf of Mexico into the Gulf Coast and Southeast. This is being squeezed out on land, and through Sunday, anywhere from 1 to 3 inches of additional rainfall is possible from southeast Louisiana into the Tennessee Valley and Southeast. This includes cities such as Atlanta and New Orleans.

Flash Flood Watches extend along the Gulf Coast from eastern Louisiana to the western Florida Panhandle, including metro New Orleans and Mobile, Ala. Soils are extremely saturated following a multitude of tropical systems over the last month or so, including Fred, Ida and Nicholas, so any slow-moving thunderstorms could quickly cause flooding.

Make sure to avoid flooded roadways. It only takes a few inches of running water to render a vehicle dangerous to operate. Remember the phrase, “Turn Around, Don’t Drown” should you come across floodwaters – the water is likely deeper than it appears.
