BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Albuquerque NM
645 PM MDT Sun Jul 26 2020

The National Weather Service in Albuquerque has issued a

* Flash Flood Warning for...
  Northwestern McKinley County in west central New Mexico...

* Until 845 PM MDT.

* At 645 PM MDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area. Between 0.5 and 1.5 inches of 
  rain have fallen. Flash flooding is ongoing or expected to begin 
  shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Doppler radar.

  IMPACT...Flooding of small creeks and streams, urban areas,
           highways, streets and underpasses as well as other
           drainage and low lying areas.

* Some locations that will experience flash flooding include...
  Western Gallup, Yah-Ta-Hey, Rock Springs, Brimhall Nizhoni, Twin 
  Lakes, Gamerco, Allison, Coyote Canyon and Mentmore.

This includes the following highways...
	Interstate 40 between Mile Markers 13 and 23.

Additional rainfall amounts of 0.25 to 0.5 inches are possible in 
the warned area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the 
dangers of flooding.

Do not enter or cross flowing water or water of unknown depth.

Arroyos, streams, and normally dry rivers can become raging killer 
currents in a matter of minutes. Water in arroyos can travel many 
miles and take hours to reach your location from upstream rain areas.

A Flash Flood Warning means that flooding is imminent or occurring. 
If you are in the warned area move to higher ground immediately. 
Take immediate precautions to protect life and property.
