Multnomah County, Ore. (Aug. 11, 2025) — Multnomah County Chair Jessica Vega Pederson today declared a state of emergency due to dangerously high temperatures, with forecasts predicting to exceed 100 degrees with little chance of overnight cooling. The emergency takes effect today, Aug. 11, at noon.
Multnomah County will open three daytime cooling centers starting today, Monday, Aug. 11, at noon. The cooling centers will provide food and water. No one will be turned away, and pets are welcome. The Homeless Services Department will also continue its ongoing emergency street outreach response to bring supplies and cooling center information to people living outside.
Cooling centers, extended library hours and community resources open
Starting today at noon, anyone needing a cool place should visit a cooling center — or any of the more than 70 cool spaces, including pools and splashpads, listed on this Multnomah County interactive map. Cool spaces like community centers, government buildings and malls — including Lloyd Center — will also be open and welcoming visitors.
From 11 a.m. to 10 p.m. today, TriMet won’t turn away anyone who is going to a cooling space and who cannot otherwise pay their fare. Please tell your bus operator that you’re heading to or from a cooling center.
For help finding a cool space or for transportation assistance to a cooling location, dial 2-1-1.
Three cooling centers will be open from noon to 9 p.m. Monday, Aug. 11:
- Gateway Church, 13300 N.E. San Rafael St., Portland, operated by Cultivate Initiatives
- Congregation Beth Israel, 1972 N.W. Flanders St., Portland, operated by Do Good Multnomah
- Portland Covenant Church, 4046 N.E. Martin Luther King Jr. Blvd., Portland, operated by Multnomah County
Cooling center flyers are available in:
Four Multnomah County library branches will also extend their hours and remain open until 8 p.m.:
- Albina Library, 205 N.E. Russell St., Portland
- Central Library, 801 S.W. 10th Ave., Portland
- Gresham Library, 385 N.W. Miller Ave., Gresham
- Midland Library, 805 S.E 122nd Ave., Portland
Heat doesn’t affect everyone equally: Who’s most at risk?
The National Weather Service has issued a heat advisory, warning that temperatures may reach or exceed 100 degrees today, with temperatures remaining near or above 70 degrees with high humidity, before temperatures are forecast to spike again on Tuesday. The forecast indicates that temperatures may start to cool off Tuesday night.
Extreme heat can be deadly for anyone in spaces without air conditioning, and it does not affect everyone equally:
- Two out of every three people who have died because of extreme heat since 2021 were men over 50.
- Most lived alone and without air conditioning.
- Heat has also particularly affected veterans who may try to “tough out” a heat wave. Overall, veterans accounted for roughly half of all recent heat deaths.
High temperatures can also be especially dangerous for people spending prolonged time outdoors, the very young, pregnant individuals, those over 50 and people with health conditions.
Public awareness and strong event planning helped keep numerous large public outdoor events Sunday mostly safe, the Health Department reported, with six emergency department visits for heat-related illness and 11 ambulance calls for people both housed and unhoused. But officials warn that the cumulative days of heat with such little overnight cooling — especially in apartments with no air conditioning — will increase risk especially for people who are homebound, elderly, have a disability or underlying health conditions.
“With two more hot days and warm nights on the way, everyone should make a plan to stay safe,’’ said Health Officer Dr. Richard Bruno.
Ongoing outreach
Cooling centers will remain open as long as conditions warrant. Additional spaces may open, and locations and hours may change, in response to evolving forecasts. Always visit multco.us/hot for the latest information.
Ahead of the heat, Multnomah County conducts outreach, calling property managers and those most vulnerable to make sure they’re prepared. The County partners with community-based organizations including Meals on Wheels People, the Center for Positive Aging and others to spread the word about heat concerns and encouraging those without air conditioning to seek cooling spaces.
The County conducted outreach to people experiencing homelessness and vulnerable clients like veterans and seniors, and contacted building managers and community-based organizations, before the heatwave began.
Multnomah County also distributed cooling kits, with cooling towels and safety information, to community-based organizations and partners at community events, libraries and apartment communities in high-risk areas.
Before an emergency is declared, the County also holds daily coordination calls with over 140 staff and partners from cities and agencies to consider opening cooling centers. Those calls include detailed briefings from the National Weather Service.
All year, multiple County programs have worked to build heat resilience in the community. The Environmental Protection Agency Environmental Justice Grant, which the federal government terminated in March, funded heat pump installation and tree plantings in low-income households in the urban heat islands in Rockwood.
Air conditioning saves lives
“It’s going to be dangerously hot the next few days, and we want to make sure people in our community are staying safe by avoiding heat and checking on neighbors and loved ones who may be at increased risk of heat-related illness,” said Dr. Bruno.
While the heat risk to people living outside is well understood, almost all heat deaths in Multnomah County since 2021 have been people who died at home. Heat is especially dangerous for people over 50, young children and people with health conditions such as heart disease. Most Multnomah County heat-related deaths during the 2021 heat dome and subsequent heat waves involved men over 50 who lived alone without air conditioning or did not use it.
Dr. Bruno urged everyone to drink more water and seek air-conditioned spaces for relief. “Air conditioning is very protective against heat and could save your life,” he said. “If you’re worried about the cost, think of it as an investment in your health, or reach out to 2-1-1 to learn about utility assistance programs.”
Stay informed and check on your community
If you are concerned someone is in heat distress, ask if they need help finding a cool space.
