From The Associated Press via The Aurora Sentinel:
Intense. Prolonged. Record-breaking. Unprecedented. Abnormal. Dangerous.
That’s how the National Weather Service described the historic heat wave that is hitting the Pacific Northwest, pushing daytime temperatures into the triple digits and breaking all-time high temperature records in places unaccustomed to such extreme heat.
Portland, Oregon, reached 110 degrees Fahrenheit (43.3 Celsius) Sunday, breaking the all-time temperature record of 108 F (42.2C), which was set just a day earlier. Oregon’s Capital city, Salem, also recorded the highest temperature in its history on Sunday: 112 F (44.4 C), breaking the old mark by 4 degrees.
Records were being broken across the region, and the sizzling temperatures were expected to get even hotter Monday.
The temperature hit 101 F (38.3 C) at Seattle-Tacoma International Airport on Sunday. The National Weather Service said that is the first time the area recorded two triple digit days since records began being kept in 1894.
It got so hot in Seattle that the city parks department closed a community pool in the southern portion of the city because of “unsafe, dangerous pool deck temperatures.”
Seattle’s light rail trains may have to operate at reduced speeds because of excessive heat on the tracks, causing delays that could continue into the work week, Sound Transit said Sunday.
The heat wave also moved into Idaho, where temperatures above 100 F (38 C) are forecast in Boise for at least seven days starting Monday. Ontario, Oregon — a city near the Idaho border — could see at least a week of triple-digit temperatures, including a high of 109 F (42.8 C) Wednesday, forecasters said.
Cities were reminding residents where pools, splash pads and cooling centers were available and urging people to stay hydrated, check on their neighbors and avoid strenuous activities…
The National Weather Service in Coeur d’Alene said this week’s weather “will likely be one of the most extreme and prolonged heat waves in the recorded history of the Inland Northwest.”
The scorching weather was caused by an extended “heat dome” parked over the Pacific Northwest. Kristie Ebi, a professor at the University of Washington who studies global warming and its effects on public health, says the days-long heat wave was a taste of the future as climate change reshapes global weather patterns.
The high temperatures were forecast to move into western Montana beginning Monday.
