Jackson, Mississippi – A widespread Gulf Coast and Mid-South rain pattern is set to intensify by Wednesday morning, bringing repeated rounds of heavy rain and slower travel across Mississippi through the end of the workweek.
According to the National Weather Service Climate Prediction Center, Mississippi is in a high-confidence zone for above-average precipitation from Wednesday through Saturday, with totals expected to run 30 to 60 percent higher than normal. A strong signal for above-normal temperatures is also in place, with a 70 to 80 percent probability of warmer-than-average conditions across the Deep South.
Jackson, Gulfport, and Hattiesburg are expected to see multiple waves of rainfall, increasing the risk of standing water on major corridors including I-55, I-20, and along the I-10 coastal stretch. In southern Mississippi, including Biloxi and Gulfport, heavier bursts could reduce visibility below one mile and overwhelm drainage systems near the coast. Northern areas such as Southaven and Tupelo may also see ponding on roadways and localized flooding in low-lying areas.
Drivers should slow down on wet roads, avoid water-covered routes, and allow extra time for travel. Residents are encouraged to clear storm drains and ensure proper drainage around homes ahead of the heaviest rain.
This active pattern is expected to continue through Saturday night, with additional advisories likely as rainfall totals and timing become more defined.
