Another day of sweltering temperatures is in store for the Northwest on Friday as another heat wave strikes the region.

Temperatures reached 102 degrees Fahrenheit by noon on Thursday, the Associated Press reported. Volunteers handed out water bottles, portable fans and popsicles as well as information about cooling shelters to people living in homeless encampments in Portland, Oregon, as temperatures climbed.

Authorities were trying to aid those vulnerable to the heat, including low-income elderly people and those living outdoors. Oregon Governor Kate Brown declared a state of emergency as the heat wave approached.

Because temperatures this high are unusual in the Pacific Northwest, it's common for people to live without air conditioning, making this year's heat waves dangerous. In June, a record-shattering heat wave killed hundreds in Oregon, Washington and British Columbia with temperatures reaching as high as 116 degrees Fahrenheit. The New York Times published an analysis this week stating that the June heat wave in the Pacific Northwest may have killed 600 people in Oregon and Washington.

Temperatures are expected to continue to be above average in the Northwest throughout the weekend and into next week.
