BELLINGHAM, Wash. — A heat advisory remains in effect across Whatcom and Skagit counties until 11 p.m. Wednesday as temperatures climb into the upper 80s and lower 90s.

“Heat will significantly increase the risk of heat-related illnesses for those who are sensitive to heat, especially those without effective cooling or adequate hydration.”

Temperatures Could Reach 92 Near Lynden

The National Weather Service forecasts a high near 91 degrees in Bellingham and 92 degrees in Lynden. Temperatures could reach 94 degrees near Diablo and 99 degrees around Darrington.

Communities along the water should remain cooler during the afternoon. Friday Harbor could reach 84 degrees, while coastal areas farther west will see substantially lower temperatures.

Overnight temperatures around 60 degrees may provide some relief. However, the prolonged heat still poses a moderate risk of heat-related illness.

The advisory covers the Whatcom and Skagit county lowlands, the North Cascades foothills and valleys, northwestern Snohomish County, Port Townsend, northern Hood Canal, the Lake Crescent area and the eastern Strait of Juan de Fuca.

Residents Urged to Stay Hydrated

Weather officials recommend drinking plenty of fluids and remaining in an air-conditioned location when possible. People should also avoid prolonged exposure to direct sunlight and check on relatives and neighbors.

Outdoor activities should be moved to the early morning or evening when possible. Those who must work outside should wear lightweight, loose-fitting clothing and take frequent breaks in shaded or air-conditioned areas.

Young children and pets should never be left unattended inside vehicles, even briefly.

Heat exhaustion can cause heavy sweating, dizziness, weakness, nausea and headaches. Anyone showing symptoms should move to a cooler location and begin cooling down.

Heat stroke may cause confusion, loss of consciousness or extremely high body temperature. It is a medical emergency, and witnesses should call 911 immediately.
