CNN)Canada, Seattle and Portland, Oregon, are all reporting their hottest temperatures on record in a wave that has more heat in store.

Seattle topped its all-time record high Sunday when thermometers climbed to 104 degrees -- so hot that even the normally freezing temperatures above 10,000 feet on Mt. Rainier reached 73 degrees.

Portland set an all-time high of 112 degrees Sunday, but that record will likely be short-lived as the forecast high Monday is 115. That would mark the third day in a row when the heat was above 107 degrees.

Temperatures are expected to remain scorching in the area until Tuesday. That is when highs are supposed to dip to 93 degrees -- still far above the usual 75 at this time of year.

Lytton, British Columbia, now holds the record for the hottest temperature ever recorded in Canada after topping out at 116 degrees Sunday. It was hotter there than in Abu Dhabi.

Record keeping in these areas dates back to the late 1800s, meaning temperatures like these haven't been seen in these regions for more than 100 years, said CNN meteorologist Michael Guy.

The heat wave is a clear example of the climate crisis affecting global weather. Climate change will also make record-breaking heat waves more frequent in the future -- and researchers and policy experts say the Pacific Northwest is not prepared.

By the middle of this century, the number of days that hit 90 degrees in the Pacific Northwest is expected to increase from a current average of around six to 16 a year, according to a study from the Union of Concerned Scientists.

Olympic trials and streetcar services shut down

At Hayward Field in Eugene, Oregon, the United States Olympic track and field trials were suspended Sunday due to extreme heat.

Sunday was the last day of the 10-day of trials and the events were scheduled to resume at 11:30 p.m. ET.

Extreme heat will be more frequent in the Pacific Northwest. Experts say it's not prepared.

Eugene set a new all-time high of 110 degrees Sunday, breaking the prior record of 108 degrees set on August 9, 1981.

In Portland, all Metropolitan Area Express Light Rail and Streetcar service has been suspended until Tuesday morning due to extreme heat, according to the Tri-County Metropolitan Transportation District of Oregon (TriMet).

"Please be sure to stay hydrated and do not travel, unless for emergencies," TriMet said in a statement Sunday night.

Bus service is still operational and TriMet said it will not turn away any customers who are unable to pay their transit fare during the extreme heat.

In Seattle, some restaurants had to close Sunday and Monday because of the heat, CNN affiliate KING reported.

"On a day like today, all bets are off," Matt Galvin, co-owner of Pagliacci Pizza in the Columbia City neighborhood, told the station.

Residents used blow-up pools, visited lakes and even stayed in hotels to get some relief, CNN affiliate KIRO reported.

Portland Parks & Recreation announced the closure of outdoor pools Monday because it is too hot for employees to be outside, CNN affiliate KATU reported.

Volunteers helped local health leaders like Dr. Jennifer Vines, health officer for Multnomah County, Oregon. Hundreds of people have used cooling centers set up since temperatures began soaring.

"People don't realize how deadly heat can be," Vines told KATU. "Northwesterners are used to cool evenings and overnights. It gives our bodies a break; it's a chance to open the windows and cool down apartments and homes. We're not going to get that these next few days."

A heat dome acts as an oven over the region

Scorching conditions in the region come from a large ridge of high pressure that has formed a heat dome, which is essentially acting as an oven to bake the region for an extended period of time.

Hot air rises, but the high pressure acts as an atmospheric lid -- forcing the hot air back to the surface where it is heated even further.

"Imagine a swimming pool when the heater is turned on -- temperatures rise quickly in the areas surrounding the heater jets, while the rest of the pool takes longer to warm up," the National Oceanic and Atmospheric Administration (NOAA) said.

The circulations within the heat dome allow temperatures to increase quickly and within a fairly confined region.

Rural eastern Oregon and Washington will feel the heat wave through the Fourth of July weekend, and eastern Idaho will also swelter.

"Right now, we're looking at 105-110 in Snake Basin of Idaho and the Treasure Valley. We could be breaking all-time records in Boise on Tuesday and Wednesday of next week." said NWS Boise Meteorologist Korri Anderson.

NWS Boise is urging people not to become another statistic, as heat-related deaths are the number one cause of weather fatalities.

"According to the CDC, over 600 people die each year from heat. It can happen to you," NWS Boise warns.
