Flash Flood, Eddy

When: June 20, 10:00 PM MST to June 21, 2:00 AM MST
Where: Eddy County, South Portion
Property damage: $20,000
Reported by: EMERGENCY MANAGER
Coordinates: 32.472, -104.304 (the zone’s center; the record gives no point)

A very tropical air mass and a shear axis in the mid levels of the atmosphere, plus slow movements of storms all added up to give Eddy County, NM excessive rains on the night of the 20th. Nine county roads were closed at one time or another, plus State Highway 128 was closed for a short time in the early morning. Several cars were stranded in water crossings, and asphalt was washed away at some crossings as well. Water flowed 14 feet deep on Higby Hill Road.

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.
