Louisiana starts the morning with damp air, patchy fog, and a steady buildup toward heavier rain across Lake Charles.
According to the National Weather Service, showers and thunderstorms will increase through late morning across Lake Charles, Sulphur, Westlake, Iowa, and Moss Bluff, with rain chances near 90% into the afternoon. Temperatures will climb from the mid-60s into the upper 60s, keeping conditions humid and unstable.
This is part of a broader Gulf-driven system feeding moisture into southwest Louisiana, supporting repeated rounds of rain and embedded storms.
The most disruptive window develops from 12 p.m. to 5 p.m., when heavier downpours may produce 0.50 to 0.75 inches of rain. Roads like I-10 and Highway 14 could see rapid water pooling, especially in low-lying stretches near downtown Lake Charles and underpasses along Ryan Street. Visibility may drop quickly during heavier bursts.
Patchy fog between 9 a.m. and 11 a.m. may already slow traffic, particularly near coastal roadways and marsh-adjacent areas. Gusty winds up to 30 mph could also knock around loose outdoor items.
Avoid driving through flooded streets and allow extra time during the afternoon commute. Keep headlights on in rain and fog to improve visibility.
Rain continues into the evening before gradually tapering, with lingering showers possible into early Saturday.

Saturday: 72°F, morning clouds then clearing
