Portland, Oregon – Record-breaking heat will continue to grip the Pacific Northwest through Wednesday, with parts of Oregon and Washington topping 100°F—up to 25 degrees above average for early June.
According to the National Weather Service’s Weather Prediction Center, temperatures in Portland soared to 105°F Tuesday and are expected to remain in the triple digits through at least Wednesday afternoon. Cities across the region, including Salem, Eugene, and Vancouver, Washington, remain under heat advisories as the high-pressure ridge stalls overhead.
In eastern Oregon and central Washington, temperatures have exceeded 100°F since Monday, straining power grids and prompting fire weather concerns in dry, windy areas. The Oregon Department of Emergency Management urges residents to avoid outdoor work during peak heat (noon to 6 p.m.), stay hydrated, and check on vulnerable neighbors.
TriMet in Portland is warning of potential delays or reduced service on MAX lines due to heat-related rail issues. Cooling centers are open across Multnomah and Clackamas counties, and public libraries are extending hours.
Relief is in sight as temperatures begin moderating Thursday, with highs expected to drop into the 80s west of the Cascades. However, fire danger will remain elevated across eastern zones.
More updates are expected Wednesday as advisories may be extended or expanded into the weekend.
