TALLAHASSEE, Fla. — Fast-moving Hurricane Helene was advancing Thursday across the Gulf of Mexico toward Florida, threatening an “unsurvivable” storm surge in northwestern parts of the state as well as damaging winds, rains and flash floods hundreds of miles inland across much of the southeastern U.S., the National Weather Service in Tallahassee said.
Helene is expected to be a major hurricane — meaning a Category 3 or higher — when it makes landfall on Florida's northwestern coast Thursday evening. As of early Thursday, hurricane warnings and flash flood warnings extended far beyond the coast up into south-central Georgia. The governors of Florida, Georgia, and the Carolinas have all declared emergencies in their states.
The weather service forecast storm surges of up to 20 feet (6 meters) and warned they could be particularly “catastrophic and life-threatening” in Florida's Apalachee Bay. It added that high winds and heavy rains also posed risks.
Early Thursday, Helene was about 350 miles (560 kilometers) southwest of Tampa and moving north northeast at 12 mph (19 kph) with top sustained winds of 90 mph (150 kph). Forecasters said it should become a major Category 3 or higher hurricane, meaning winds would top 110 mph (177 kph).
