A red flag warning has been issued for Wednesday for eastern Washington and Oregon because of high dry conditions, strong winds and high temperatures.
Most of central and southeastern Washington and northeastern and central Oregon will be at heightened fire risk, the National Weather Service said.
The warning begins at 1 p.m. and will last until 10 p.m. Winds begin mid-day, building from breezy to windy through the afternoon and evening. Winds are expected to be between 15 mph and 25 mph with gusts of 40 mph.
Humidity will drop to 13 percent, making it dry ground cover in the region even more susceptible to fire.
