AccuWeather delivers life-saving advance notice to businesses, schools and hospitals on New York City flooding

On September 29, 2023, the New York City metro area experienced devastating flash flooding caused by persistent heavy downpours. The intense rainfall led to life-threatening flash flooding that turned streets into raging rivers, flooded subways and led to the evacuation of hospitals and schools.  AccuWeather For Business helped companies be the best prepared and saved lives by providing the earliest advance notice, the most accurate forecasts, and the best description of impacts.

MOST ADVANCE NOTICE

The heavy rain persisted for several hours, with rainfall rates surpassing 3 inches per hour. As the rain intensified, AccuWeather Storm Warning meteorologists issued a SkyGuard® Flash Flood Warning that EXCLUSIVELY provided 17 ADDITIONAL minutes of life-saving advance notice for imminent flash flooding in parts of Western Brooklyn and Lower Manhattan when compared to the warnings issued by the public government and other sources.  

As Wednesday and Thursday progressed, the forecast became more dire: AccuWeather was the first to highlight the potential for flooding on Friday, issuing a "watch for flooding" forecast on Wednesday, a day in ADVANCE of the National Weather Service (NWS), which issued a Flood Watch only on Thursday afternoon.

AccuWeather Storm Warning Meteorologists issued a Storm Potential Notice (SPN) early Thursday morning, more than 8 hours in ADVANCE of the NWS and other sources issuing a Flood Watch. AccuWeather’s SPN forecasted downpours and flash flooding across NYC, emphasizing the risk of rainfall rates exceeding 1 inch per hour, particularly in urban areas.

ACCUWEATHER’S SUPERIOR ACCURACY

AccuWeather For Business expert meteorologists were the first to predict "street flooding and more serious flash flooding in places," emphasizing the rapid escalation of life-threatening situations in urban areas like NYC. By highlighting these dangers, AccuWeather helped businesses be best prepared and helped save lives. 

AccuWeather accurately forecasted the risk of 4-8 inches of rain in specific locations, including Brooklyn, Queens, and parts of Nassau County. Other sources provided less precise estimates, demonstrating AccuWeather's superior forecasts. AccuWeather was also extremely accurate with where the rain would occur.
