Hurricane Erin
Hurricane Erin remains a powerful and expansive storm Tuesday morning, even after weakening slightly from its Category 5 peak over the weekend. As of the latest advisory, Erin is a Category 2 hurricane with sustained winds of about 105 mph, but its size has grown dramatically. The storm’s tropical-storm-force winds extend nearly 200 miles from the center, meaning its impact is being felt far beyond its eye. Erin is forecast to remain offshore, passing roughly 200 miles east of North Carolina’s Outer Banks on Thursday, but the threat it poses to the East Coast is very real.
Coastal communities in North Carolina are already bracing for serious flooding, beach erosion, and pounding surf. Officials have issued evacuation orders for vulnerable barrier islands such as Hatteras and Ocracoke, with warnings that Highway 12 could become impassable from ocean overwash. Forecasters expect waves between 10 and 15 feet along the Outer Banks, with isolated sets closer to 20 feet. Storm surge of 1 to 4 feet is possible during high tide, particularly in low-lying areas, creating dangerous conditions for anyone near the water. Farther up the East Coast, Erin’s massive wind field is generating life-threatening rip currents and dangerous surf from Florida through New England. The Red Cross has already reported dozens of rescues tied to rip currents over the last week, with lifeguards warning swimmers to stay out of the water. Beaches in the Mid-Atlantic and Northeast are forecast to see surf of 7 to 12 feet by Thursday, while Long Island and coastal Connecticut could see swells in the 10- to 15-foot range offshore. Even in areas hundreds of miles from the storm, Erin is making the Atlantic a dangerous place for both swimmers and mariners.
Erin’s lifecycle has been remarkable: it formed near Cape Verde on August 11, intensified quickly into the season’s first hurricane by August 15, and exploded into a Category 5 storm just one day later. Though it has weakened after an eyewall replacement cycle, its reach has expanded, making it one of the most widespread threats of the season. After skirting the East Coast, Erin is projected to accelerate northeastward into the Atlantic, passing south of Newfoundland this weekend and transitioning into a non-tropical system. But Erin may not be the end of the story. Behind it, the National Hurricane Center is tracking two additional tropical disturbances moving across the Atlantic. One of those systems already has a 50 percent chance of developing into a tropical cyclone within the next week, raising concerns that the active season is far from over. For now, the message from forecasters is clear: Erin may not make landfall, but its size, power, and position offshore make it a dangerous storm that demands attention up and down the East Coast.
