News Summary
New Orleans is under a flash flood warning due to severe thunderstorms causing heavy rainfall. The warning, activated by city officials, includes measures for safe parking and cautions against flooded roads. Residents are urged to monitor local alerts and take safety precautions as urban flooding risks rise from inadequate drainage systems and expected additional rainfall.
New Orleans is currently under a flash flood warning due to severe thunderstorms that have impacted the region. The warning was issued on Friday, June 11, 2025, before 11:45 a.m. and is expected to last until 2:45 p.m. City officials have activated neutral ground parking to allow residents to park their vehicles safely until 6 p.m. in anticipation of flooding conditions.
The thunderstorms that moved into the area have been associated with a complex system of showers that also extends into St. Tammany Parish. Residents are warned that, as of the latest forecast, between 0.5 to 2 inches of rain have already fallen, with an additional 1 to 2 inches anticipated. Storms capable of producing heavy rainfall may lead to rapid urban flooding, exacerbating existing risks in areas with inadequate drainage.
Due to the severe weather conditions, specific prohibitions have been put in place. As of 10:50 a.m., the Lake Pontchartrain Causeway Bridge was closed to motorhomes, motorcycles, and glass trucks due to strong wind gusts. This precautionary measure aims to prevent accidents and ensure public safety amid worsening conditions.
The National Weather Service (NWS) has classified the weather risk across southeast Louisiana and all of South Mississippi as a level 1 marginal risk. Furthermore, as the situation progressed, a flash flood emergency was declared for parts of East Baton Rouge Parish following significant rainfall that resulted in accumulations between 3.5 to 4.5 inches by Saturday evening. The forecast suggests a further inch or two could follow.
In addition, Flood Watches remain in effect for millions of residents throughout Louisiana and surrounding states. Meteorologists warn that potential rainfall accumulations may reach between 4 to 6 inches throughout the week. Persistent showers and thunderstorms are likely to continue into the weekend, keeping communities on alert for flooding issues.
Local officials are advising residents to exercise extreme caution regarding driving conditions. The Rayne Police Department has issued advisories urging drivers to avoid flooded roadways due to safety concerns both for personal safety and the potential for significant property damage. Furthermore, hazardous flooding conditions have also led to the temporary closure of polling locations, affecting voters seeking to participate in local elections.
With street flooding already occurring in parts of New Orleans as of Wednesday morning, the NWS has made clear the significant risk of urban flooding is compounded in areas with poorly maintained drainage systems. Public works crews are expected to respond accordingly to alleviate water pooling in affected locations. As these storms progress, individuals in the area are encouraged to stay tuned to local alerts to remain informed about changing conditions.
As the storm system continues to impact New Orleans and surrounding regions, residents are advised to take proactive safety measures, remain indoors when possible, and closely monitor weather updates. Emergency services and city officials are preparing to provide assistance as necessary and respond to any localized flooding incidents that may occur.
