Baton Rouge, Louisiana – A warmer-than-normal and wetter weather pattern is expected to settle across Louisiana heading into Valentine’s Day weekend, increasing the likelihood of periods of rain, fog, and travel slowdowns from Saturday through midweek. While no single severe system is currently indicated, repeated rounds of rainfall could create cumulative impacts on roads, rivers, and low-lying communities statewide.
According to the National Weather Service Climate Prediction Center, Louisiana is favored for above-normal precipitation and above-normal temperatures during the February 14–18 period. This setup supports mild daytime conditions while allowing multiple moisture-rich systems to move across the Lower Mississippi Valley and central Gulf Coast.
In southeast Louisiana, including Baton Rouge, New Orleans, and the Northshore, periods of steady rain could lead to ponding on roadways and reduced visibility along I-10, I-12, and I-55, particularly during overnight and early morning hours. Fog development is also possible as warm, humid air moves over cooler ground and waterways.
Across south-central Louisiana, including Lafayette, Houma, and Thibodaux, rain is expected to be the dominant precipitation type. Repeated showers may overwhelm storm drains at times, increasing the risk for localized poor drainage flooding in urban areas.
In northern Louisiana, including Shreveport, Monroe, and Ruston, persistent rainfall could raise water levels on smaller streams and bayous. Travel along I-20 and U.S. 165 may slow during heavier rain bands, especially where water collects on road surfaces.
Along the coast, including Cameron Parish and Plaquemines Parish, rainfall combined with high tides may increase the risk for minor flooding in low-lying and flood-prone locations. Emergency officials advise monitoring drainage systems and avoiding water-covered roads.
Air travel through Louis Armstrong New Orleans International Airport and Baton Rouge Metropolitan Airport may see occasional delays during periods of low clouds or heavier rain, though widespread disruptions are not expected. Utilities report no elevated concerns for wind or ice-related outages under this warmer pattern.
This warmer, wetter setup is expected to persist into midweek. Additional advisories may be issued as individual systems become clearer, and residents are urged to stay alert for updated alerts, especially during overnight and early morning travel periods.
