The Pacific Northwest is experiencing unusually high temperatures for September, with Portland hitting 102°F and Seattle expecting highs above 90°F. This extreme heat has already led to seven suspected heat-related deaths in Multnomah County, with officials urging residents to stay hydrated and check on vulnerable neighbors. Cooling centers and extended river rescue services have been activated to help those without access to air conditioning. Denver is also facing significant heat, experiencing its second-warmest summer since 1872, with multiple days reaching triple digits. Relief is expected over the weekend as cooler, more humid air moves in, bringing temperatures down to the low-mid 80s in Portland and mid-70s in Seattle. Highs in the 70s and 80s are forecasted for next week, providing a much-needed break from the heat.
