News Summary
New Orleans is bracing for significant rainfall and potential flooding as a tropical system approaches. A flood watch has been issued, and residents are preparing by filling sandbags. Concerns have risen over the city’s capacity to manage the expected downpour, with meteorologists forecasting rainfall rates that could exceed three inches per hour. City officials have identified high-risk areas for flooding and have announced temporary road closures to mitigate risks as they monitor the storm’s progression.
New Orleans is gearing up for significant rainfall and potential flooding as a tropical system known as Invest 93L approaches the region, with heavy rains expected to begin Thursday and continue into the weekend. Local officials are emphasizing the risk of receiving a month’s worth of rain in just one day, which has raised alarms among residents about possible flash flooding and water accumulation.
A flood watch has been issued for southeast Louisiana from Wednesday through Saturday morning, and meteorologists have forecasted rainfall rates in some storms that could exceed 3 inches per hour. Such rates would likely overpower the city’s drainage capabilities, thus raising concerns about rapid flooding.
As a precautionary measure, residents are actively preparing for the storm by filling sandbags to protect their homes, churches, and apartments, with reports indicating some individuals have spent over an hour waiting in lines to acquire supplies in areas like Gentilly. City officials are also monitoring the situation closely, with updates on the storm expected at 5 p.m. Wednesday.
At present, out of the 93 major drainage pumps in New Orleans, 86 are operational; however, two turbines are currently out of commission and available only for emergency use. Comparatively, neighboring Jefferson Parish reported that all 194 pumps were operational as of Tuesday. The city’s drainage system is designed to handle 1 inch of rain in the first hour and 0.5 inch per hour afterward, confirming concerns about its ability to cope with expected rainfall.
Forecasting data suggests that while previous estimates of rainfall have been reduced, significant amounts are still likely. Areas south of Interstate 10 may experience between 2-3 inches, while parts of Acadiana might see up to 4-8 inches. There is also the potential for localized torrential downpours, heightening the risk of flash flooding particularly in urban centers.
The National Weather Service has warned of excessive rainfall as the storm is anticipated to move slowly, further increasing the flooding risk. As of Wednesday morning, Invest 93L was located near Tallahassee, Florida, with indications that conditions were still disorganized. Meteorologists report the storm has a 40% chance of developing into a tropical depression or storm before making landfall, and if it does gain strength, it would be named Dexter, marking the fourth named storm of the 2025 Atlantic hurricane season.
In New Orleans, officials have identified 15 intersections that are at high risk for flooding, notably in areas like Gentilly and Algiers. To mitigate chaos as the storm approaches, multiple intersections will be temporarily closed due to expected heavy rains. Additionally, the city has lifted parking restrictions on neutral grounds starting at 7 p.m. Wednesday, allowing for better drainage and emergency response facilitation.
In anticipation of the weather event, city buildings will be closed to the public on Thursday; however, city services will remain available virtually to ensure continued support for residents despite the adverse weather conditions. City officials are advising everyone to stay informed and prepared as Invest 93L approaches.
