Tropical Storm Isaias killed at least five people as it whipped up the East Coast on Tuesday, including several people whose deaths are being blamed on falling trees. Mario Siles, 60, was found inside a 2014 Dodge van “with trauma about the head and body,” a New York Police Department spokeswoman said. He was pronounced dead at the scene, the spokeswoman added. An 83-year-old woman in Delaware was found around noon under a large branch in a pond near her home, Cpl. Jason Hatchell with Delaware State Police told CNN. In St. Mary’s County in southern Maryland, the driver of a car died after a tree fell on the vehicle’s roof. Earlier, at least two people were killed when a tornado struck a mobile home park in Windsor, North Carolina, Bertie County officials said. Twelve people were injured and taken to hospitals. A resident of the neighborhood told CNN affiliate WRAL she hid in her bathroom with her two sons. “We didn’t have a lot of time to react once it finally hit. I mean, it hit all at once,” Desaree Pike said. “For lack of a better word, it was hell. You don’t really think about anything else but just holding the kids and hoping it doesn’t tear the house up.” Follow live coverage of Isaias’ destructive path Sheriff John Holley told the station: “It’s bad. It doesn’t look real. It looks like something on TV. Nothing is there.” There have been preliminary reports of more than 30 tornadoes along the East Coast. The storm has knocked out power to more than 3 million customers, according to poweroutage.us. As of 8 p.m. ET, Isaias was grinding through the New England states as it headed to Canada, the National Hurricane Center said. “During the past few hours, there have been numerous reports of wind gusts of 40-50 mph (65-80 km/h) across portions of Rhode Island, eastern Massachusetts, and southeastern New Hampshire,” the hurricane center said. What makes Isaias particularly dangerous is how quickly it’s traveling. By Tuesday evening, the storm was heading north-northeast at 40 mph. The storm still had maximum sustained winds of 50 mph. That rapid movement means Isaias won’t weaken very much as it continues up the East Coast, CNN meteorologist Chad Myers said. It also means tornadoes can drop with little or no warning. “If you get a (tornado) warning on your phone, make sure you pay attention to it,” Myers said. “You might not have 20 minutes with storms like this.” Isaias made landfall as a Category 1 hurricane late Monday near Ocean Isle Beach, North Carolina. It was downgraded to a tropical storm Tuesday. More than 61 million people were under a tropical storm warning as of Tuesday afternoon. And more than 10 million people were under some form of flood warning or watch. Heavy rain brings flood in Pennsylvania Some East Coast cities were deluged with torrential rainfall and storm surges. A resident of Allentown, about 65 miles north of Philadelphia, tweeted video of the dumpters near her unit at the Auburn Station Apartments being swept away. “Rain slowing but water continues to rise. We are in a bit of a valley right here so it may be worse than the rest of Allentown,” Stephanie Eckelkamp wrote in the early afternoon. Philadelphia was pummeled with more than 4 inches of rain and saw wind gusts of up to 44 mph. ‘Life-threatening’ floods and collapsed houses Brunswick County in southeastern North Carolina reported “numerous calls for water rescues, structural fires, structural collapses and people trapped in houses that were flooding,” Oak Island Water Rescue said on Facebook. The town issued mandatory evacuations and instituted a curfew from 6 p.m. to 6 a.m ET. Howling wind and water washing across in “one to two foot swells” closed a bridge Monday night in Sunset Beach, North Carolina, the Sunset Beach Police said on Facebook. Streets in Holden Beach became rivers as water quickly rose, Jessi Viox told CNN. Even before Isaias made landfall, the top of the Apache Pier Pavilion was seen lifting off in the wind. And multiple structures in Ocean Isle Beach caught fire, according to the Horry County Fire Rescue in South Carolina. A hurricane warning was in effect from the South Santee River area in South Carolina to Surf City, North Carolina, meaning hurricane conditions are expected somewhere within the warning area, NHC said. “The wind and flooding impacts from Isaias will be similar to what the city has seen from some of the strongest coastal storms,” such as nor’easters – “but we haven’t seen one this strong in many years,” he said. “But we haven’t seen one this strong in many years.” The National Weather Service said that LaGuardia Airport had one gust of 69 mph Tuesday. New York installed temporary barriers to prevent flooding in Lower Manhattan. And in Maryland, Gov. Larry Hogan suspended Covid-19 testing operations at community-based sites for Tuesday. Curfews and evacuations in parts of North Carolina The North Carolina Department of Transportation (NDOT) evacuated more than 3,000 people from Ocracoke Island on Monday, CNN affiliate WAVY-TV reported. The barrier island, which has an elevation of 3 feet at its highest point, is only reachable by boat or aircraft. It was hit hard by Hurricane Dorian in September 2019. “The most important thing is to get out of harm’s way if you are told to evacuate. Try to have a plan to stay with friends or family outside the danger zone,” Gov. Roy Cooper said Monday. On the mainland, citizens were stocking up supplies for the storm. “You never know. We’ve been hit with worse surprises, so there really is no amount of over-preparations that you can do,” Eli Thompson, of Avon, told WAVY-TV.
