Summary

Hurricane Helene was a catastrophic and deadly tropical cyclone that struck the Southeastern United States in late September 2024. It formed in the western Caribbean Sea on September 22, 2024, rapidly intensifying to a Category 4 hurricane before making landfall near Perry, Florida, on September 26, 2024, with sustained winds of 140 mph. Helene caused widespread devastation, including record storm surge in Tampa Bay, significant rainfall-triggered flooding in western North Carolina, East Tennessee, and southwestern Virginia, and numerous tornadoes. The storm resulted in 252 deaths and an estimated $78.7 billion in damages, making it the fifth-costliest Atlantic hurricane on record adjusted for inflation. Its increased intensity has been linked to record ocean warming, a phenomenon exacerbated by the removal of sulfur dioxide emissions from shipping, which also posed a significant threat to the Florida real estate and insurance markets.

Hurricane Helene

Hurricane Helene ( heh-LEEN) was a deadly and devastating tropical cyclone that caused widespread catastrophic damage and numerous fatalities across the Southeastern United States in late September 2024. It was the strongest hurricane on record to strike the Big Bend region of Florida, the deadliest Atlantic hurricane since Maria in 2017, and the deadliest to strike the mainland U.S. since Katrina in 2005. The eighth named storm, fifth hurricane, and second major hurricane of the 2024 Atlantic hurricane season, Helene began forming on September 22, 2024 as a broad low-pressure system in the western Caribbean Sea. By September 24, the disturbance had consolidated enough to become a tropical storm as it approached the Yucatán Peninsula, receiving the name Helene from the National Hurricane Center. Weather conditions led to the cyclone's intensification, and it became a hurricane early on September 25. More pronounced and rapid intensification ensued as Helene traversed the Gulf of Mexico the following day, reaching Category 4 intensity on the evening of September 26. Late on September 26, Helene made landfall at peak intensity in the Big Bend region of Florida, near the city of Perry, with maximum sustained winds of 140 mph (220 km/h). Helene weakened as it moved quickly inland before degenerating to a post-tropical cyclone over Tennessee on September 27. The storm then stalled over the state before dissipating on September 29. In advance of Helene's landfall, states of emergency were declared in Florida and Georgia due to the significant impacts expected, including very high storm surge along the coast and hurricane-force gusts as far inland as Atlanta. Hurricane warnings also extended further inland due to Helene's fast motion. The storm caused catastrophic rainfall-triggered flooding, particularly in western North Carolina, East Tennessee, and southwestern Virginia, and spawned numerous tornadoes. Helene also inundated Tampa Bay, breaking storm surge records throughout the area. The hurricane had a high death toll, causing 252 deaths and inflicting an estimated total of $78.7 billion in damage, making it the fifth-costliest Atlantic hurricane on record adjusted for inflation.

Some estimates put the [...] The system that became Helene emerged as a region of scattered thunderstorms in the western Caribbean Sea on September 23, 2024. By late morning the next day, the system was centered nearly 150 miles (about 240 km) west of the Cayman Islands and became more organized. Meteorologists at NOAA’s National Hurricane Center classified it as a tropical storm, naming it Tropical Storm Helene, and forecast that the storm’s path would take it northeastward across the Gulf of Mexico to strike Florida. [...] Five hours after becoming a category 4 storm, at 11:10 pm, Helene slammed into Florida’s Big Bend region some 40 miles (70 km) southeast of Tallahassee, with heavy rains and roaring winds that raged at 140 miles (225 km) per hour. It brought a 15-foot (4.5-meter) storm surge to the beachfront communities of Keaton Beach and Steinhatchee.
