PORTLAND, Ore. (AP) — The mayor of Portland, Oregon, warned the Pacific Northwest could see the most dangerous part of a multiday heat wave this weekend.
Portland and Seattle appear to be on track to break records for extended scorching temperatures.
Authorities are investigating whether the heat was to blame for the deaths of at least five people in Oregon.
Temperatures have neared the triple digits in Portland the entire week, hitting a high of 102 degrees Fahrenheit (38.9 Celsius) on Tuesday.
Forecasters predict temperatures could top 100 F (37.8 C) once again on Saturday.
