New Orleans residents should brace for more unsettled skies Monday as September storms threaten travel and outdoor plans across southeast Louisiana. Afternoon downpours and lightning could slow traffic along I-10 and surface streets, with the greatest threat between 1 p.m. and 6 p.m.
According to the National Weather Service, storm chances return Monday with scattered thunderstorms developing after midday. Light winds will increase slightly, pushing humid air across Jefferson and Orleans parishes. Storms could briefly drop heavy rain, leaving slick roads and localized ponding during the evening commute.
Sunday remains mostly sunny, offering a brief window for outdoor activities. Temperatures climb near 90 degrees, but rising humidity will make it feel warmer. By Monday, clouds thicken and rain chances rise, with showers expected to linger into Tuesday.
Drivers along I-10, the Crescent City Connection, and major routes through Gretna and Metairie should plan for slower travel. Keep headlights on during downpours and allow extra time on the roads. Residents are urged to charge devices and secure loose outdoor items ahead of gusty winds.
Rain chances persist through midweek, with thunderstorms possible Wednesday and lighter showers carrying into Thursday and Friday. Conditions will stay muggy, with highs near 90 degrees daily and lows in the mid-70s overnight.
Storm activity may remain scattered, but repeated rounds of showers could disrupt daily routines across the metro. More updates are expected as advisories evolve into the workweek.
