Severe storms, floods and tornadoes expected in the central Gulf Coast
A highly amplified cyclone can burst out with severe storms and tornadoes in the south-central U.S. on March 21-22.
Residents of southern parts of Louisiana and Mississippi must prepare for thunderstorms, which may bring significant tornadoes, hail and wind gusts, according to the Storm Prediction Center. The severe weather conditions will start forming above Texas on March 21 afternoon, and are expected to peak through March 22.
Communities in central Texas might be the first to encounter tornadoes. While those living in the vicinity of Sabine River Valley of east Texas and western Louisiana are at much higher risk when the storm intensifies.
As the cold atmospheric front keeps moving steadily in the eastern direction, it will carry damaging winds, tornadoes, and hail across the central Gulf Coast States in the direction of southern Alabama and Florida Panhandle. The potential threat is likely to diminish overnight into March 23.
The risk areas include the cities of Baton Rouge, Hattiesburg, Lafayette, Metairie, and New Orleans in the state of Louisiana; as well as the cities of Clinton, Hattiesburg, Jackson, and Pearl in the state of Mississippi.
The National Weather Service issued a flood warning for residents of the parishes of West Feliciana, East Baton Rouge, and Pointe Coupee in the state of Louisiana, who live in the vicinity of the Mississippi river.
The flooding in these areas is expected to be minor, but it is important to take extra care along the riverbanks and abstain from flooded roads while in vehicles. The flood warning is in force until the early morning of March 23.
The territory of the U.S. has the largest number of tornadoes per year. Climate change contributes to the frequency and unpredictability of tornado events linked to the warming of the ocean water surface and related increase of atmospheric moisture content. The latter can contribute to tornado activity, especially in cold seasons.
