KENMORE, Wash. — Three firefighters were treated for heat exhaustion Wednesday as Eastside crews battled fires in temperatures nearing triple digits.

Firefighters responded to a Kenmore house fire, a Yarrow Point boat fire and a brush fire near Issaquah. No one was hurt in any of the blazes.

The fire in Kenmore broke out about 4 p.m. in a one-story home in the 19500 block of 65th Avenue Northeast. When firefighters arrived, the house was engulfed in flames, said Terri Jones, spokeswoman for the Northshore Fire Department.

No one was home at the time, but three dogs escaped unharmed, Jones said.

Three firefighters battling that blaze were treated at the scene for heat exhaustion as temperatures reached the upper 90s. It was unclear whether they required further care.

In Yarrow Point, a fire started about 4:30 p.m. in a 32-foot cruiser docked at a home on Lake Washington, said Bellevue fire Lt. Eric Keenan. The wind blew the flames over the dock and into a 22-foot ski boat. Both boats, valued at $125,000 and $55,000, were destroyed, Keenan said.

The owner of the boats and the house, in the 8800 block of Northeast 36th Street, was home at the time.

Fire crews are still investigating the cause of the Kenmore and Yarrow Point fires.

About three hours earlier, fire crews in the Klahanie neighborhood near Issaquah responded to a brush fire behind an apartment building in the 3800 block of Klahanie Drive Southeast.

The fire covered about 100 square feet and took more than three hours to put out, said Brian McMahan, battalion chief for Eastside Fire & Rescue.

Fire crews suspect that the fire was caused by children who were playing in the woods the night before.
