Dangerous flash flooding is predicted to hit Louisiana and Mississippi, bringing severe weather to the region. With heavy rainfall expected, flash flooding poses serious risks. This comes on the heels of a week where storms have already claimed the lives of at least 75 people in the United States.
Flash Flooding and Rainfall Rates
Rainfall rates of 2 to 3 inches per hour are expected, which can lead to flash flooding, particularly in urban areas. The slow-moving axis of intense rainfall further heightens the risk. Cities such as New Orleans, Baton Rouge, Lafayette, Jackson, Hattiesburg, Biloxi, and Gulfport are at high risk for flash flooding.
There is also a possibility of localized heavy rainfall, with totals ranging from 10 to 12 inches. The ground is already saturated, so these additional rainfall rates can create deadly flash flood conditions. It’s important to note that rushing water on roadways can be deceptive, especially at night.
River Flooding and Severe Weather
Apart from urban flash flooding, river flooding is a major concern. The Trinity, San Jacinto, and Navidad rivers in southeastern Texas are expected to rise to a major flood stage in the next 24-48 hours.
Severe weather is also anticipated along the Gulf Coast, extending from south Texas to western Alabama. Cities like New Orleans, Baton Rouge, and Mobile face the greatest risk of severe thunderstorms. Wind gusts over 60 mph, isolated tornadoes, and damaging hail are all possible.
Safety Precautions
The combination of strong winds and flooding increases the risk of downed trees and power lines. It is crucial to stay away from downed power lines and avoid any water near them, as electrocution can occur.
As an active weather pattern affects much of the eastern United States, it is important to remain cautious. While the southern states brace for heavy rain, the northern states, including the Midwest, the Great Lakes, the Northeast, and New England, are experiencing wintry precipitation with freezing rain and snow.
