August 14, 2021

This post was updated at 1 p.m. Aug. 14 to include that The Oregon Medical Examiner today determined that the one death in Multnomah County under investigation is not related to the heat.

With an excessive heat advisory in effect until 10 pm tonight, Multnomah County and City of Portland 24-hour Cooling Centers remain open one more night for those seeking a place to cool down.

Commissioner Sharon Meieran visited Kellogg Middle School and worked as a medical volunteer.

Hot temperatures are expected to continue through the day, and temperatures are expected to gradually cool over the weekend. Much cooler temperatures are expected early next week. Smoke is also expected to slowly diminish through the weekend, which should bring cleaner air into the area.

While some relief is expected, residents are urged to practice caution by continuing to monitor themselves for heat illness and having access to a cool space throughout the day. 2-1-1 remains available for transportation assistance, and TriMet will not turn anyone away seeking relief from hot temperatures.

“Several days of high temperatures stresses our bodies,” said Health Officer Dr. Jennifer Vines. “Everyone should continue to have a plan to stay cool and help others do the same.”

24-hour Cooling Centers open until 9 a.m. Sunday, Aug. 15

Multnomah County and City of Portland are committed to offering 24-hour cooling spaces as long as excessive heat affects the area. The following 24-hour Cooling Centers remain open one more night. 

Multnomah County libraries also remain open for the day. The following sites will be open until 8 pm tonight.

Multnomah County, City of Portland utilize Wireless Emergency Alert system for heat emergency

Yesterday the City of Portland and Multnomah County sent a Wireless Emergency Alert (WEA) for severe heat shortly after 10 a.m. The message, delivered in English and Spanish, was sent to every mobile phone in Multnomah County and some phones in surrounding counties.  

This marks the County and City’s first use of the Wireless Emergency Alert system to warn people of hot weather. The National Weather Service frequently utilizes the system for other weather emergencies, including dust storms, extreme wind, flash floods, hurricanes and typhoons, severe thunderstorms, storm surges on the coast, tornadoes and tsunamis.

The County and city of Portland sent two previous Public Alerts regarding dangerous heat on July 28 and on Wednesday, Aug. 11. But those alerts reached a limited number of landlines and people who signed up for Public Alerts

“Our number one priority is saving lives,” said Alice Busch, a City-County Unified Commander. “Heat kills and yet many in our community are unaware of this. We are committed to using every tool available to communicate with and protect those in Multnomah County who are most vulnerable or isolated.”
