High temperatures, low moister and moderate breezes created a high risk of fire in most of Western Washington and Western Oregon over the next two days.
The National Weather Service issued a Red Flag Warning until 9 p.m. tonight and from 11 a.m. until 9 p.m. Friday.
Red Flag Warnings are meant for emergency managers and fire agencies so they can boost staffing or proposition resources. The warnings mean that critical fire weather conditioning are currently happening or will in the near future.
Washington’s North Coastal Lowlands, Central and South Puget Sound areas, and Southwest Coast up to East Skamania County are affected.
Roughly the western third of Oregon, from the coast to Hood River and south to the California state line, is affected.
Officials say in the conditions fire starts will have the potential to spread rapidly and the atmosphere’s instability would allow fire plumes to rise quickly.
Relative humidity is projected to be as low as 10 percent, with temperatures in the upper 90s on Friday afternoon.
A heat advisory is also in effect from Thursday until 8 p.m. Friday evening. The Weather Service warns elderly, youth and those without air conditions to take extra precautions to stay cool.
Southwest Washington’s weather conditions are expected to cool off on Sunday with highs near 80 and going into the 70s for the rest of the week.
