Flash Flood Warnings Hit New York and Carolinas After Heavy Storms

The short answer

A flash flood warning is issued when rapid flooding is imminent or occurring. Recent examples include a Sunday warning in Onondaga County, NY, where slow-moving storms flooded roads in DeWitt and Minoa, and a multi-day threat in the Carolinas from Tropical Storm Bertha moisture, which dropped over 5 inches of rain in coastal areas.

Why it's trending

Multiple flash flood warnings were issued in the last few days: a localized warning in Onondaga County, NY on Sunday and ongoing flood threats in the Carolinas from Tropical Storm Bertha remnants.

Flash flood warnings were issued in separate parts of the U.S. as heavy rain triggered rapid flooding. In Onondaga County, New York, a slow-moving thunderstorm prompted a brief flash flood warning Sunday, with reports of flooded roads in DeWitt and Minoa, according to Meteorologist Josh Kozlowski of WSTM.

Meanwhile, the Carolinas faced a multiday flooding threat from lingering moisture associated with Tropical Storm Bertha. FOX Weather reported that some areas received over 5 inches of rain in two days, leading to flash flooding on Friday, including on Interstate 26 in Asheville, North Carolina.

The National Weather Service issued the warning for Onondaga County after slow-moving downpours hit eastern parts of the county. Two confirmed reports of flooding came from near Haddonfield Drive and Alwyn Road in DeWitt, and from Windebank Lane in Minoa, where roads and driveways were inundated.

In the Carolinas, the flood threat was expected to diminish by Sunday as the front moved offshore. The rainfall was welcomed in drought-stricken areas but caused hazardous conditions in urban and low-lying regions.
