BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Reno NV
744 PM PDT Sun Jul 27 2025

The National Weather Service in Reno has issued a

* Flash Flood Warning for...
  Southern Washoe County in western Nevada...

* Until 830 PM PDT.

* At 744 PM PDT, Trained weather spotters reported thunderstorms 
  producing heavy rain across the warned area. Up to 0.5 inches of 
  rain have fallen. Flash flooding is ongoing or expected to begin 
  shortly.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Baron Burn Scar near Rattlesnake Mountain. The 
debris flow can consist of rock, mud, vegetation and other loose 
materials.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Trained spotters reported.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
   Baron Burn Scar near Rattlesnake Mountain in Reno.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Heavy rainfall will cause extensive and severe flash flooding of 
creeks...streams...and ditches in the Baron Burn Scar. If you 
encounter flood waters...climb to safety.

Recent burn areas are more prone to flooding, debris flows, and rock 
falls. Plugged culverts, rocks and debris on roads, and water and 
mud over roads are common during moderate to heavy rains. Increased 
sediment and debris can lead to impacts in areas typically not prone 
to flooding. Use extra caution when traveling in or below recent 
burn areas. Impactful flooding and debris flows may be generated by 
15 minutes or less of heavy rainfall.
