Hurricane Nate weakened to a tropical depression on Sunday after coming ashore in Mississippi, flooding roads and buildings but sparing the state from catastrophic damages.Maximum sustained winds from Nate, the fourth major storm to hit the United States in less than two months, dropped to 35 miles per hour (55 km per hour) as it moved through Alabama and into Tennessee.The remnants of the storm spawned tornado warnings in those states and the western portions of North Carolina and South Carolina. It is forecast to bring gusty winds and up to 4 inches (10 cm) of rain to parts of Ohio, Pennsylvania and New York on Monday.The storm made landfall as a Category 1 hurricane, the weakest designation by the US National Hurricane Center. Only a few hours earlier, its winds had been blowing at 70 mph (113 kph) but appeared to lack the devastating punch of its recent predecessors.Mississippi Governor Phil Bryant told reporters there had been no deaths or reports of catastrophic damage. "We are very fortunate this morning and have been blessed," he said.Nate killed at least 30 people in Central America before entering the warm waters of the Gulf of Mexico and bearing down on the US South. It has also shut down most oil and gas production in the Gulf.Nate follows hurricanes Harvey, Irma and Maria, which have devastated areas of the Caribbean and southern United States. The tropical depression's center will move up through Alabama into Tennessee and Kentucky through Monday, the hurricane center said. Heavy rainfall and storm-surge flooding remained a danger across the region, and the hurricane center said Florida's Panhandle and parts of Alabama and Georgia might feel tropical storm-force wind gusts.The storm was expected to bring three to six inches of rain to parts of western North Carolina through midday Monday, with up to 10 inches possible in isolated spots. Power outages, damaged homes and roads closed by debris were all reported in the region.Nate made its first US landfall on Saturday evening near the mouth of the Mississippi River and then made a second one early on Sunday near Biloxi, Mississippi.In Biloxi, water surged over roads during the storm and quickly receded on Sunday, leaving a boat that broke loose marooned on the beach. At a Waffle House restaurant, the storm surge deposited a dumpster in its parking lot.Jeff Pickich, a 46-year-old wine salesman from D'Iberville, Mississippi, was counting his blessings. Heavy winds left only minor damage, blowing down part of a fence on his rental property in Biloxi."I'm just glad," he said, digging fresh holes for fence posts. "I was afraid of the water. The water is Mother Nature. You can't stop it."Water flowed through Ursula Staten's yard in Biloxi, pushing over part of her fence and scattering debris, but did not breach her house."I have a mess," the retired massage therapist said. "If we had got Irma, I would have lost everything." At the Golden Nugget Casino, one of eight Biloxi gaming establishments, workers rushed to clean up mud, debris and minor damage from 3 feet (1 m) of water sloshing into an entrance and the parkade. The gaming room stayed dry.Three hundred guests remained in the hotel, some eager to try their luck after surviving Nate.But dangers from the storm remain, with Florida Governor Rick Scott warning of tornadoes springing up in the Panhandle region and Alabama Governor Kay Ivey urging residents to prepare for strong winds and storm surges.US President Donald Trump declared federal emergencies in Alabama and Florida on Sunday, which provides additional funding for disaster relief.Mississippi Power had restored electricity to 10,000 customers, but 4,800 were still without it. More than 1,000 people had arrived at shelters, the state Emergency Management Agency said.Alabama Power said it had restored electricity to 58,000 of 146,000 customers who lost it.Rainfall of 3 to 6 inches (8 to 15 cm), with a maximum of 10 inches (25 cm), was expected east of the Mississippi River in Alabama and Tennessee, the hurricane center said.
