Tropical threat puts New Orleans on high alert for flash flooding
The sandbags are filled in New Orleans, the pumps are prepped and now the region waits for the tropical system that has the potential to dump a month's worth of rain in a single day. Why it matters: New Orleanians are on edge about flash flooding, which happens too frequently in this city below sea level. The big picture: The tropical system, called Invest 93L, is in the Gulf and expected to reach Louisiana's coast Thursday. It may develop into a tropical depression, the National Hurricane Center said Wednesday. It will be named Dexter if it strengthens into a tropical storm. Flooding is the biggest concern for New Orleans, according to the National Weather Service's Slidell office. Threat level: A flood watch is in effect for southeast Louisiana from Wednesday through Saturday morning. Multiple rounds of heavy rainfall are expected through at least Saturday morning, NWS said. The greatest threat is Thursday and Friday. Up to 10 inches could fall in places, which is more than the average rainfall for the entire month of July, NWS said. New Orleans is most likely to get 2 to 3 inches by Saturday night, with higher totals on the coast, according to the Wednesday forecast. Between the lines: Rainfall rates in some of the storms could be more than 4 inches per hour, which is faster than the pumps can drain streets. On the street: New Orleanians waited in line for about an hour Wednesday in Gentilly to fill up sandbags to protect their homes, apartments and churches. "Hopefully, I won't need them," said Robert Johnson, a longtime Gentilly resident. "It's just erring on the side of caution." That was the vibe from others as they shoveled their bags in the sweltering heat. Their homes have flooded or gotten close to flooding in recent thunderstorms and they want to be proactive. And residents like Lynelle Batiste told Axios New Orleans they're concerned the pumps won't be able to keep up. The location had 1,000 DIY bags available, according to Councilman Eugene Green, and stayed open after the designated time due to demand. Drainage prep Drainage pumps in New Orleans and Jefferson Parish can handle 1 inch of rain the first hour and 0.5 inch per hour after that when the systems are working at full capacity. When rain falls too quickly, it overwhelms the pumps, causing street flooding. Authorities in both parishes say they are focusing on cleaning catch basins before the rain arrives. The Sewerage & Water Board said 86 of 93 major pumps (map) were working as of Wednesday. Two of its power turbines were down and available only for emergency use. All of the underpass pumps were working, SWBNO said, with the exception of one of the three that drain the Carrolton Avenue/I-10 underpass. In Jefferson Parish, all 194 pumps were working as of Tuesday, said drainage director Ben Lepine. Employees have also tested the generators and are ready to staff pumping stations 24 hours a day if needed, he said in a statement. Entergy said it is monitoring the storm and preparing for severe weather in south Louisiana. The company has materials, supplies and staffing available if needed, a spokesperson told Axios New Orleans. Go deeper

Gulf coast braces for flooding as storm system builds into possible tropical depression
The tropical weather system moving across the Florida Panhandle on Wednesday was showing a greater chance of becoming a tropical depression as it moves toward the northern Gulf Coast, according to the National Hurricane Center. The weather system has a 40% chance of becoming a tropical depression as it moves west toward southeastern Louisiana on Thursday, the federal agency said. The tropical weather will affect Alabama and Mississippi as well. Regardless of whether the system worsens, heavy downpours could cause flooding, officials warned. New Orleans is bracing for three to five inches of rain through Saturday, but some localized areas could see more than eight to 10 inches, especially near the coast, the National Weather Service said. 'While a tropical depression cannot be ruled out near the coast on Thursday, the main focus remains the heavy rain threat,' the agency wrote on X. The looming threat in the southeast comes on the heels of a series of lethal floods this summer. On Monday, flash floods inundated New York City and parts of New Jersey, claiming two lives. And at least 132 people were killed in floodwaters that overwhelmed Texas Hill Country on the Fourth of July. The current system percolating over Florida would be called Tropical Storm Dexter if it becomes a named storm. Just six weeks into the Atlantic hurricane season, which runs from June 1 to Nov. 30, there have been three named storms: Andrea, Barry and Chantal. Dexter would be the fourth if it develops that way. Chantal made landfall in South Carolina last week, and its remnants caused flooding in North Carolina that killed an 83-year-old woman when her car was swept off a rural road. The National Oceanic and Atmospheric Association said there was a 60% chance that there will be more named storms this hurricane season than there have been in past years on average. The currently developing weather system is expected to move fully inland by the end of the week. ____
