Severe Storms to Slam Northeast as 32M Face Dangerous Flooding Threat

Forecasters said rainfall rates of 1 to 2 inches per hour could overwhelm drains and trigger rapid flooding in cities.

  • More than 32 million people across the Mid-Atlantic faced a flash flood threat on Thursday as thunderstorms developed and moved toward the East Coast, with New York City, Philadelphia, and Baltimore in the path of the heaviest rain.
  • The National Weather Service Storm Prediction Center warned that thunderstorms could produce rainfall rates of 1 to 2 inches per hour, which can overwhelm storm drains in urban areas where impervious surfaces prevent water absorption.
  • Forecasters noted the greatest concern for flash flooding lies along and near the Interstate corridor, where storms could also bring damaging wind gusts, frequent lightning, and isolated tornadoes.
  • Dangerous travel conditions were expected to overlap with the evening commute, and authorities advised motorists to find alternate routes rather than attempting to cross flooded underpasses or low-lying roads.
  • Severe weather threats extend beyond the Northeast, with storms from Nebraska into Wisconsin capable of producing large hail and wind gusts of 55 to 75 mph, while strong thunderstorms are possible across the Carolinas, Tennessee Valley, Deep South, and the Plains.
