The current heat wave means local counties and cities are quickly being added to jurisdictions with a burn ban in effect.
The burn ban in King County goes into effect on Saturday.
Thursday was the hottest day of the year so far in Seattle and temperatures are expected to stay over 80 degrees for the next week.
Many other counties are already under the ban, including, Snohomish, Pierce, Kitsap, Mason, Skagit and Whatcom.
The Stage 1 Burn Ban in effect in King County allows for fires in designated concrete or fire pits and says that fires must be away from vegetation.
On Friday, firefighters were busy responding to brush fires on Friday -- from Lynnwood to East Pierce County.
An active wildfire was also burning in Mason County Friday in the Brockdale, Johns Creek area. Chopper 7 flew over the fire. See that video here.
