FlowCore Predictions of Floodwater Depth and Property-Level Damage for Long Island

FlowCore Predictions of Floodwater Depth and Property-Level Damage for Long Island

FlowCore predictions of floodwater depth and property-level damage for Long Island resulting from flash flooding in August.

On August 18–19, an isolated storm caused devastating flash flooding in Stony Brook, New York, leading to the collapse of the dam at the Mill Pond. The extreme weather triggered evacuations and rescues and caused major damage to infrastructure. Roads buckled and collapsed, and erosion continued even after the storm. The draining of Mill Pond also resulted in the loss of much of the local wildlife.

Western Suffolk County saw a record 9.4 inches of rain in just 24 hours—a 1-in-1000-year event. In response, Governor Kathy Hochul, in collaboration with FEMA, DHSES, and the U.S. Small Business Administration, provided relief to help communities recover.

This event highlights the increasing risk of severe flooding as storms become more intense and capable of heavier downpours. A FEMA emergency declaration is expediting efforts to rebuild and strengthen critical infrastructure.
