1 flash flood. Local standard time, as filed.

Flash Flood, Herkimer

When: June 23, 1:11 AM EST to 5:00 AM EST
Where: Herkimer County, Mohawk
Reported by: EMERGENCY MANAGER
Coordinates: 43.420, -74.962 (the zone’s center; the record gives no point)

Heavy rains, associated with a slow moving warm front, produced up to 3 inches of rainfall in a few hours during the overnight of June 22-23 across the southern Adirondacks and Western Mohawk Valley. As a result, the Spencer and Fulmer Creeks briefly overflowed in Mohawk, Herkimer County. There were no significant problems reported to the National Weather Service with either of these creeks flooding.

What these are

Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
