Issaquah is under a regional red flag warning as a combination of strong winds, low relative humidity and high temperatures create explosive fire growth potential.
National Weather Service meteorologists in Seattle said the red flag warning is in effect until 8 p.m. Thursday.
The combination of wind and humidity can cause fire to spread rapidly. Other factors could lead to larger fires. The red flag warning means critical fire weather conditions already started, or could occur shortly.
Meanwhile, smoke from wildfires in Central and Eastern Washington reached the Puget Sound region.
Smoke from the lightning-sparked wildfires is causing air quality problems throughout the state.
Wildfires produce harmful smoke. The biggest threat to people’s health comes from fine particles in smoke. The tiny particles can get into eyes and lungs, where they can cause health problems, such as burning eyes, runny nose and illness, such as bronchitis.
The fine particles also can aggravate heart and lung diseases, and even lead to death.
