The US National Hurricane Center (NHC) has issued hurricane, tropical storm, and storm surge warnings for the Louisiana state coast from Intracoastal City to Grand Isle as of 19:00 (local time) on Thursday, July 11. A tropical storm watch is also in effect for the Mississippi state coast. Tropical Storm Barry formed in the Gulf of Mexico earlier on Thursday and is located approximately 280 km (175 mi) southeast of Morgan City (LA) with maximum sustained winds of 75 kph (45 mph). Barry is forecast to continuing moving north in the coming hours and make landfall over the central or southeastern coast of Louisiana by late Friday night, July 12, or the early morning hours of Saturday, July 13. The storm is expected to continue to strengthen over the coming hours and may become a hurricane as its center nears the coast. Further hurricane, tropical storm, and storm surge warnings are possible for other parts of the US Gulf Coast in the coming hours, including east Texas, Alabama, and the Florida panhandle.
Heavy rain, storm surges, and damaging winds are expected to affect parts of Louisiana and southwest Mississippi as Barry moves inland. Storm surges up to 1-1.8 m (3-6 ft) are possible along with rainfall totals of 25-50 cm (10-20 in) and 63 cm (25 in) in isolated areas. Intense flash flooding already inundated parts of New Orleans (Louisiana state) on Wednesday, July 10, and further flooding is likely for the region along with strong winds and associated damage and disruptions. Louisiana Governor John Bel Edwards declared a state of emergency across the state on Wednesday ahead of the expected storm. Power outages, downed trees, infrastructure damage, road closures, and flight and rail delays and cancelations are possible.
Individuals in the affected areas are advised to monitor local weather reports, adhere to instructions issued by local authorities, ensure adequate food, water, battery, and medical supplies, and anticipate severe weather, flooding, strong winds, and associated power, telecommunication, and transportation disruptions.
Remember that walking or driving through water can be dangerous and floodwater may contain wastewater and chemical products.
