Which Category 4 hurricane struck Florida's Big Bend region in September 2024 and became the deadliest to hit the U.S. mainland since Katrina?

Hurricane Helene made a devastating landfall in Florida's Big Bend region in late September 2024, confirming its place in history as a powerful Category 4 storm. This immense hurricane, which struck near Perry, Florida, with sustained winds reaching 140 miles per hour, became the deadliest to impact the U.S. mainland since Hurricane Katrina in 2005. Its catastrophic force led to a tragic loss of life, with hundreds of fatalities reported across multiple states, particularly in North Carolina, which bore a significant brunt of the storm's fury.

The formation of Helene was notable for its rapid intensification as it traversed the warm waters of the Gulf of Mexico. Forecasters tracked its swift development from a tropical storm to a major hurricane, recognizing its unusually large size and the potential for widespread destruction. This rapid strengthening contributed to the extreme danger posed by the storm, leading to severe and life-threatening storm surges along Florida's west coast, with some areas experiencing inundation of more than 16 feet.

Beyond the immediate coastal impact, Helene's fast forward motion meant that its destructive hurricane-force winds and torrential rainfall extended far inland across the southeastern United States. Communities in Florida's Big Bend experienced immense structural damage, widespread power outages, and landscapes altered by the floodwaters. The storm's remnants continued to bring significant rainfall and wind damage as it moved into Georgia, Tennessee, Kentucky, and Indiana, underscoring the vast reach and profound impact of this historic weather event.
