Severe storms dumped heavy rain across New York State on Sunday evening. On Monday morning, people woke up in some areas to impassable roads, flooded homes, stranded vehicles, and other damage. At least one death was confirmed by authorities overnight. 

The Hudson Valley area is the most affected by the storm. Meteorologists say the region that stretches along the Hudson River from Westchester County to Albany received upwards of five and eight inches of rain in six hours. Some called yesterday's rainfall event a "once-in-1,000-year rainfall event." 

A once-in-1,000 year rainfall event has occurred in the last 6 hours in the Lower Hudson Valley, north of #NYC. Up to 8 inches of rain has fallen in just 6 hours in the region, particularly from Peekskill to Woodbury. Major flooding is ongoing. #NYwx pic.twitter.com/OlM0G1lrlM
