Hurricane Erin, which vaulted from Category 1 to Category 5 in just 24 hours last weekend, is now a Category 1 storm with maximum sustained winds near 90 mph as it accelerates northeastward hundreds of miles off the U.S. East Coast, according to the National Hurricane Center. Although weakening, Erin remains unusually large, with hurricane-force winds extending 125 miles from its center and tropical-storm-force winds reaching 370 miles. The storm’s broad wind field has generated a coastal onslaught. North Carolina’s Outer Banks saw storm surge and flooding that closed portions of Highway 12 and prompted the evacuation of roughly 2,200 people from Ocracoke Island. A NOAA buoy east of Cape Hatteras logged a 45-foot wave, and the National Weather Service reported 10-to-20-foot seas from the Carolinas to New England, along with life-threatening rip currents stretching as far south as Florida. Farther north, New Jersey Governor Phil Murphy declared a state of emergency as high tides and 20-foot waves inundated shore roads. Ferry services between Boston and the Cape and Islands were canceled, beaches from Maryland to Massachusetts barred swimming, and wind gusts of 45–50 mph lashed Cape Cod and Nantucket. Similar hazardous surf is affecting South Florida, while Puerto Rico is still cleaning up flooding and earlier power outages tied to Erin’s rapid intensification phase. Forecasters expect Erin to lose tropical characteristics over the weekend while still producing dangerous surf and minor to moderate coastal flooding through at least Saturday. The hurricane’s remnants are projected to pass south of Atlantic Canada before turning toward the North Atlantic. Meanwhile, the NHC is monitoring three additional disturbances that could develop in the coming days, underscoring what is forecast to be an above-average Atlantic hurricane season.
