The U.N. World Meteorological Organization (WMO) Tuesday called the heatwave hitting the Pacific Northwest corner of the United States “exceptional and dangerous,” and says it could last at least another five days. Speaking to reporters from Geneva, a WMO spokeswoman said while records have fallen in the U.S. states of Oregon and Washington, western Canada has seen extreme heat as well. Extreme #heat hits Northwest USA and Western Canada, which saw new record temperature of 47.9°C

— World Meteorological Organization (@WMO) People look for ways to cool off at Willow’s Beach during the ‘heat dome,’ currently hovering over British Columbia and Alberta as record-setting breaking temperatures scorch the province and in Victoria, British Columbia, Canada, June 28, 2021.The WMO said the extreme heat is caused by “an atmospheric blocking pattern,” which has led to a “heat dome” — a large area of high pressure — trapped by low pressure on either side. The organization said the temperatures would likely peak early this week on the coast and by the middle of the week in the interior of British Columbia; afterward, the baking heat is expected to move east toward Alberta. The U.S. National Weather Service in Portland, Oregon, on its Twitter account late Monday, reported cooler air was already in the region along the coastline. In a tweet Sunday, the Oregon Climate Service said the climate system is no longer in a balanced state, and such heat events “are becoming more frequent and intense, a trend projected to continue.”
