Beaumont, Texas – Scattered afternoon thunderstorms could drench parts of Southeast Texas and Southwest Louisiana through Tuesday, bringing brief torrential downpours, lightning, and a low-end flood risk in urban areas.
According to the National Weather Service in Lake Charles, a weak disturbance aloft is enhancing storm development, especially across Acadiana and coastal zones. Rain chances will peak Monday and Tuesday, ranging from 60% to 80% in cities like Lafayette, Lake Charles, and Beaumont. Most storms are expected during the late afternoon and evening hours.
Localized street flooding is possible, especially where storms stall or repeat. Areas such as New Iberia, Opelousas, and Leesville may see high rainfall rates in short bursts. Drivers are urged to avoid water-covered roadways and remain indoors during thunder. Heat remains a secondary hazard, with heat indices climbing above 100°F during rain-free hours.
By midweek, a strengthening upper-level ridge will limit storm activity while pushing heat indices into the 105–106°F range by Friday across Alexandria, Lafayette, and Jasper. Officials recommend staying hydrated, taking cooling breaks, and checking on vulnerable populations.
Storm chances begin to taper off by Wednesday, but heat impacts will intensify. Additional heat advisories may be issued later this week.
