Although not as extreme as the one in the Pacific Northwest, the Northeast is enduring its own heat wave this week.

After hitting at least 90 degrees Monday, temperatures are forecast to remain in the 90s in the big cities of the Northeast through Wednesday. Three days of highs in the 90s officially constitutes a heatwave in the region, according to AccuWeather.

High humidity and light winds add to the heat misery. 

In the Willamette Valley south of Portland, Oregon, a farmworker died Saturday at a workplace as temperatures that day hit 104 degrees. 

Officials have not yet released details about where the individual was working, who the person was or how exactly he or she died.
