July 2023 Northeastern United States floods
The July 2023 Northeastern United States floods, also known as the Great Vermont Flood of 10–11 July 2023 in Vermont, was a destructive and significant flash flood event occurring in the Northeastern United States from July 9 to 29, 2023. Slow-moving showers and thunderstorms produced heavy rainfall and flooding, which led to widespread damage across multiple states in the Mid-Atlantic, with the heaviest and most destructive flash flooding centered around northern New England, specifically Vermont. Across the affected areas, numerous roads and bridges were washed out, and dozens of water rescues were conducted. Widespread rainfall amounts of 5 inches (130 mm) fell across the Northeast, with the maximum amount of rainfall occurring in Putnam Valley, New York, with 10.49 inches (266 mm). Downtown Montpelier, Vermont was flooded, as numerous state roads around the city were closed. The flash floods caused 13 fatalities across several states and $2.2 billion in damage.
