PORTLAND, Ore. (AP) — Oregon’s largest city broke its all-time heat record Saturday. It could beat the new mark on Sunday. Forecasters say many Pacific Northwest communities may sweat through the hottest days in their histories as temperatures soar during a heat wave that has sent residents scrambling for relief. Stores sold out of portable air conditioners and fans, hospitals canceled outdoor vaccination clinics, cities opened cooling centers, baseball teams canceled or moved up weekend games and utilities braced for possible power outages. Portland, Oregon, reached 108 degrees Fahrenheit (42.2 degrees Celsius) Saturday afternoon, according to the National Weather Service. The previous heat record for Oregon’s largest city was 107 F (41.7 C), a mark hit in 1965 and 1981.
