“Temperatures in the Pacific Northwest will see highs in the 80s and 90s, which will represent anomalies of 20 to 30 degrees,” forecasters said. Weather forecast center said Saturday. “Many parts of the Pacific Northwest Coast will tie or break temperature records this weekend.”
The Seattle area is expected to hit a high of 87°F on Saturday and Sunday. If the temperature reaches 90°F, it will break the May 17, 2008 record for the first 90 degree day of the year. Temperatures in the region are expected to be in the low to mid-80s through next week, forecasters said.
Several cooling centers opened in the Seattle area this weekend in anticipation of the heat wave, according to the King County Regional Homelessness Authority.
While Portland, Oregon has yet to open official cooling centers, local officials have urged people to seek respite from the heat at local libraries, community pools or drinking fountains. Alberta in Canada has declared a provincial state of emergency and asked more than 29,000 people to evacuate their homes.
