* WHAT...For the Heat Advisory, temperatures between 93 and 97 degrees expected. For the Extreme Heat Watch, dangerously hot conditions with afternoon temperatures between 90 and 100 degrees and low temperatures between 65 to 70 degrees possible. * WHERE...Western and Central Columbia River Gorge and the Hood River Valley, Portland Metro Lowlands, Greater Vancouver Metro, and Central Willamette Valley. * WHEN...For the Heat Advisory, from 11 AM to 10 PM PDT Sunday. For the Extreme Heat Watch, from Tuesday afternoon through Wednesday evening. * IMPACTS...Heat related illnesses increase significantly during extreme heat events. * ADDITIONAL DETAILS...There is a 50-75% chance that Tuesday night low temperatures remain above 65 degrees and a 15-25% chance low temperatures remain above 70 degrees, which would limit overnight relief. The highest chances are in the Portland/Vancouver Metro Area and Columbia River Gorge. There is also 20-40% chance for high temperatures of 100 degrees or hotter across the Willamette Valley on Tuesday and Wednesday.
Drink plenty of fluids, stay in a cool place during the heat of the day, stay out of the sunshine, and check up on relatives and neighbors. For those without air conditioning, use fans to keep air moving. Keeps windows closed during the day and open at night, unless air quality is degraded due to wildfire smoke. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. Monitor the latest forecasts and warnings for updates. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. 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 9 1 1.
