Chelan County Burn Area Decision Support Web Page
The National Weather Service, in partnership with local, county, and state officials, have developed a list of weather resources for those affected by the 2012, 2013 and 2014 wildfires in Chelan County. The Mills Canyon burn scar of 2014 has the greatest increase in risk for debris flows and flash floods this Summer. Risk of Flash Flooding from burned areas remains heightened for several years after wildfires. Areas that still have a higher risk of flash flooding are: Mission Creek, No. 1 and No. 2 Canyons above Wenatchee, Crum Canyon, Oklahoma Gulch, Byrd Canyon, First Creek above Lake Chelan State Park, Colockum Creek, Tarpiscan Road, Bjork Canyon & Eagle Creek Road. Please monitor this web page for the most up to date weather information.

Increased risk of flash flooding and debris flows remain as a result of the 2012, 2013 and 2014 Wildfires in Chelan County

Wildfires and Flooding
Floods are the most common and costly natural hazard in the nation. Whether caused by heavy rain, snow melt or thunderstorms, the results of flooding can be devastating. While some floods develop over time, flash floods, particularly common after wildfires, can occur within minutes after the onset of a rainstorm. Even areas that are not traditionally flood prone are at risk due to changes to the landscape caused by fire.

Chelan County 2012, 2013 and 2014 Burned Area
In the aftermath of the wildfires near Wenatchee, Washington, locations within, adjacent to, and downhill from the burned areas are more susceptible to flash flooding and debris flows during intense Summer thunderstorms. The fact that many of the fires burned in steep, mountainous terrain increases the post-fire flash flood risk. The Mills Canyon burn scar of 2014 has the greatest increase in risk for debris flows and flash floods this summer. While some of the older burn areas have begun to see regrowth of vegetation, the risk remains heightened for 3 to 5 years following intense fires. Areas that still have a heightened risk of flash flooding and debris flows during intense rainfall include Mission Creek, No. 1 and No. 2 Canyons above Wenatchee, Crum Canyon, Oklahoma Gulch, Byrd Canyon, First Creek above Lake Chelan State Park, Colockum Creek , Tarpiscan Road, Bjork Canyon & Eagle Creek Road. Detailed maps of the burned areas can be found?here. here.

How Can I Be Prepared?
In the event of moderate to heavy rainfall, do not wait for a flash flood warning in order to take steps to protect life and property. Thunderstorms that develop over the burned area may begin to produce flash flooding and debris flows before a warning can be issued. If you are in an area vulnerable to flooding and debris flows, plan in advance so you know how you will safely evacuate to higher ground. There may be very little time to react once the storms and rain start.

Monitor Weather Alerts and Forecasts
Knowing ahead of time when precipitation is likely to occur will allow you to be better prepared. Monitor NOAA Weather Radio for all forecasts and statements and be prepared to take action should flash flood warnings be issued.
Listen to Emergency Responders
Heed the advice and recommendations from local law enforcement and transportation officials pertaining to road closures and any evacuation plans.
