Atmospheric River Bringing Heavy Rain to Southern California and Heavy Snow to the Sierra Nevadas

A strong atmospheric river will continue heavy rain over southern California through Friday. The heaviest rainfall is ongoing today in the Los Angeles Basin. Flash and urban flooding is possible. A prolonged heavy snowfall has begun over the Sierra Nevada Mountains and will continue through Friday. Travel will become increasingly difficult over the passes due to snow and strong winds.

The National Weather Service and other local emergency services partners have created this resource to detail the higher probabilities of Flash Flood and Debris Flows across western and central Wyoming for those people affected by the 2012 Wildfires.

***While this page highlights the burn scar associated with the Gilead Wildfire, these impacts can occur down slope and/or downstream of any burn area, big or small. Please contact local officials if you are unsure of your risk.***

Greatest Risk Area

All low lying areas, flood plains, current and historic channels
Anywhere that gravity will move water and debris
Note: Water and debris can be transported into areas that don't normally see water flow. All areas in and downslope of burned areas should be aware of the increased probability of Flash Flood and Debris Flows
Streams Impacted
Rock Creek
South Rock Creek
Pheasant Creek
Mowry Creek
Red Creek
North Fork Sayles Creek

Variables Affecting Magnitude of Flash Flood/Debris Flow:
Steepness of terrain above your location
Intensity of burn
Intensity of rainfall
- Half inch of rain in less than one hour can result in a Flash Flood
- Any high intensity rain over a short period of time can result in a Flash Flood
- Age of burn scar
- Threat lessens over time; highest probability the first year after the fire
Most burn areas will be flash flood prone for at least 2 years

What should people who live near burn areas do to protect themselves from potential Flash Flooding and Debris Flows?

Have an evacuation/escape route planned that is least likely to be impacted by Flash Flooding or Debris Flows
Have an Emergency Supply Kit available
Stay informed before and during any potential event; knowing where to obtain National Weather Service (NWS) Outlooks, Watches and Warnings via the NWS, website, Facebook, Twitter, or NOAA Weather Radio
Be alert if any precipitation develops. Do not wait for a warning to evacuate should heavy precipitation develop
Call 911 if you are caught in a Flash Flood or Debris Flow
