Heavy Rainfall and Severe Thunderstorm Threats for the Plains and Southeast

A frontal boundary extending from the western High Plains to the Southeast will focus additional showers and thunderstorms this weekend. Some of these storms may become severe, alongside frequent lightning, and isolated instances of flash flooding. Meanwhile dry conditions will continue for the Great Basin where fire weather concerns linger. For the mid-Atlantic and Northeast, seasonable weather. Read More >

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 Wyoming for those people affected by the 2019 Roosevelt Fire.

***While this page highlights the burn scar associated with the Roosevelt Fire, 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

Creeks / Streams Impacted

Upper Hoback River
(above the Jamb Creek confluence)
South Fork Hoback River
Kilgore Creek
Sled Runner Creek
Fisherman Creek
South Fork Fisherman Creek
Stub Creek
Muddy Creek

Other Impacted Areas

Hoback Ranches
Upper Hoback Road (Road 23174)
Fisherman Creek Road
Riggan Lane
Rim Road
Deer Haven Road
Some locations in Hoback Ranches will be more susceptible to flash flooding and debris flows than other areas (click here for a zoomable map).

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
