Strong high pressure over the Pacific Northwest will bring a stretch of unseasonably hot weather to much of southwest Washington and northwest Oregon.

Temperatures will already be in the low to mid 90s beginning Friday, but increase further to dangerous levels Saturday through Monday. High temperatures will run 20 to 30 degrees above normal for late June at many locations, putting numerous daily, monthly and possible all-time high temperature records in jeopardy.

Overnight lows will also be unseasonably warm, limiting the amount of relief from the heat and contributing to increased risk of heat related illnesses. The heat is expected to peak Sunday, then gradually trending downward towards the middle of next week. However even next week will be 10 to 20 degrees above normal.

Dangerously hot conditions with temperatures between 100 and 108. Highest temperatures are expected on Sunday. Overnight lows remaining in the upper 60s to low 70s.

Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.

The hot daytime temperatures, combined with warm overnight lows, will result in high heat risk and heat related stress.

Smoke from wildfires may also affect the situation.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.

Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments.

Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 911 if needed.
