Lake Charles, Louisiana – A sweltering heatwave gripping southwest Louisiana and southeast Texas is expected to intensify Sunday, with heat index values reaching as high as 108°F and a chance of strong thunderstorms overnight.
According to the National Weather Service in Lake Charles, a weakening line of storms may push through the region late Sunday into early Monday, bringing isolated wind gusts above 58 mph, especially across central Louisiana. A slight risk (Level 2 of 5) for severe weather is in effect for areas including Alexandria and Oberlin, while Lafayette and Lake Charles remain under a marginal threat.
Daytime highs will hover in the low- to mid-90s through Thursday, but oppressive humidity will make it feel much hotter. Cities like Beaumont, Cameron, and Port Arthur are urged to limit outdoor activity, wear light clothing, and stay hydrated. Heat exhaustion remains a serious risk with extended exposure.
Storms tonight could cause brief power outages or downed limbs, particularly along I-49 and US 165 corridors. While widespread severe weather is not expected, residents should monitor alerts and have multiple ways to receive warnings.
Warnings for heat and storm impacts remain in effect through Monday morning. Additional advisories may be issued.
