Lake Charles, Louisiana – Southwest Louisiana is bracing for severe heat and afternoon thunderstorms on Thursday, August 14, creating hazardous conditions across Calcasieu Parish and surrounding areas. According to the National Weather Service (NWS) in Lake Charles, residents should prepare for heavy rain, gusty winds, and possible power disruptions as storms develop between 1 and 5 p.m. Thursday. The heaviest rain is expected just before the evening commute, with the potential for brief downpours and frequent lightning.
While rainfall amounts are expected to be light overall, these storms could bring quick, intense bursts of rain, along with gusty winds. The heat index could climb to a dangerous 105°F, especially if sunshine breaks through earlier in the day, exacerbating heat risks for those outdoors. Travelers in the region are advised to stay alert, as heavy rain can lead to slick roads and reduced visibility.
Drivers along major highways, including I-10, I-210, and Highway 90, should be prepared for sudden changes in weather. Officials warn to avoid flooded intersections and expect slower travel times as conditions worsen in the late afternoon. With lightning and strong gusts expected, power outages may also be a risk across the region.
Looking ahead, Friday and Saturday will mirror Thursday’s weather pattern, with highs in the low to mid-90s and a 40–60% chance of afternoon storms. While Saturday could bring slightly drier air, pop-up thunderstorms will remain a possibility. Sunday’s forecast calls for highs near 95°F, pushing the limits of heat safety for outdoor plans, with a 30–50% chance of afternoon thunderstorms.
The National Hurricane Center is monitoring a low-probability disturbance in the Bay of Campeche, but it is not expected to develop significantly, with only a 10% chance of formation through early next week.
Despite the absence of tropical threats, residents should continue to monitor weather updates, as the thunderstorm activity is expected to persist through early next week. As conditions change, the NWS will provide updated advisories, urging the public to stay alert to potential storms through Monday and Tuesday.
