Record-breaking heat wave hits Pacific Northwest, millions under advisory.

An early heat wave is expected to hit the Pacific Northwest, possibly breaking temperature records and worsening wildfires in western Canada. The National Weather Service issued a heat advisory for parts of Oregon and Washington state, warning of the risk of heat-related illness. The unseasonal high temperatures could further fuel the dozens of fires burning in Canada's western Alberta province. Residents and officials in the Northwest have been trying to adjust to the likely reality of longer, hotter heat waves following the deadly “heat dome” weather phenomenon in 2021 that prompted record temperatures and deaths across the region.
