The National Weather Service prediction center released a hazardous heat map for Sunday that shows much of Oregon is expected to see unusually warm temperatures.
The weather service is predicting “dangerously hot conditions” with high temperatures Sunday ranging from 100 to 105 in the Portland metro area. The temperatures aren’t expected to drop much overnight, with lows ranging from the mid-60s to low 70s.
The excessive heat warning has begun and is expected to be in place for days.
The National Weather Service and other government agencies are advising Oregonians to take precautions in the excessive heat. Local metro area cooling centers plan to open Friday.
The extended forecast for Sunday through Thursday reads:
“Major heat will continue to make weather headlines for the West Coast states, with 100+ degree high temperatures extending to northern Washington for the entire forecast period. Highs will likely reach the 110s for the lower elevations of inland California, southern Nevada, and southern Arizona, with some 120s possible for the normally hotter locations.
“Some of this extreme heat will likely expand eastward to include much of the Intermountain West, including Utah and Idaho where some triple digits readings are expected. Numerous daily records are likely to be established during this prolonged and dangerous heat event, with major to extreme heat stress conditions.
“Even Wyoming and Montana get above average temperatures by next Wednesday/Thursday as the upper ridge slowly moves inland across the Rockies.”
Much of the West Coast including Oregon and into northern Washington are in the area of expected hazardous heat Sunday.National Weather Service
