The Pacific Northwest is facing its second major heat wave of the summer, following an early heat wave in May. The extreme heat first arrived in parts of Washington and Oregon state on Sunday and is expected to last through the week.
The Pacific Northwest largely avoided the excessive heat waves that tormented much of the southern and northeastern United States earlier this summer.
An excessive heat warning is in effect through Wednesday night, though there is a risk the heat will persist through Friday, according to The National Weather Service.
Washington and Oregon residents face extreme heat
In Portland, Oregon, highs could reach 107 on Monday and 104 on Tuesday before dropping below triple digits on Wednesday. Temperatures in Seattle this week will be the warmest recorded this year with afternoon highs in the 80s and low 90s.
Wildfires threaten the Pacific Northwest
This week’s extreme heat will increase wildfire threats in the region. In western Washington and Oregon, red-flag warnings for high fire danger are in effect. The Lookout Fire led to evacuations late Sunday in eastern Lane County, Oregon.
Record high temperatures expected in parts of Washington, Oregon
The ongoing heat wave has the potential to shatter Salem, Oregon’s previous August temperature record, if the temperature climbs above 108°F. In areas spanning the Willamette Valley, from Salem to Eugene, temperatures could surge between 105°F and 110°F on Monday.
In Yakima, Washington, a high of 107°F is projected for Tuesday, surpassing the previous daily record of 103°F set in 2021. Similarly, Kennewick, Washington anticipates a high of 108°F on Tuesday, breaking the previous daily record of 104°F set in 2021.
How to stay safe during a heat wave
Authorities strongly advise residents and visitors who don’t have access to cool or air-conditioned spaces to limit their heat exposure. The National Weather Service recommends staying hydrated, limiting strenuous outdoor activities, as well as keeping pets out of locked vehicles.
