North-West summit ‘heat dome’ raises temperatures – WKRG News 5
SEATTLE (AP) – Portland, Ore., Broke their all-time heat record on Saturday. He then beat it again on Sunday, recording a temperature of 112 degrees Fahrenheit (44 degrees Celsius), breaking the record set a day earlier of 4 degrees.
Seattle, known nationally for its mild weather and rainy days, hit 104 F (40 C) on Sunday. The National Weather Service said this was an all-time record for the city and the first time the region had recorded two consecutive triple-digit days since records began to be kept in 1894.
And temperatures were predicted to be even warmer on Monday. What’s going on?
The Pacific Northwest is experiencing a multi-day heat wave that forecasters have called “historic”, dangerous and harbinger of things to come as climate change affects global weather conditions.
WHY IS IT SO HOT IN THE NORTHWEST NOW?
Temperatures began to rise on Friday and are not expected to cool until Tuesday, with mercury registering more than 30 degrees warmer than normal in many parts of Washington and Oregon. The cause is a “heat dome” which affected parts of the West for about two weeks. Justin Pullin, a meteorologist with the Seattle Weather Service, said a strong peak of high pressure is causing temperatures more associated with Arizona than the northwest.
“The heat that we have experienced over the past two days… is very unusual and historic. We’re talking about all the temperature records that are broken, in some cases 5, 10 degrees, ”Pullin said.
ARE HOT TEMPERATURES CAUSING PROBLEMS?
Normal routines have been disrupted as governments and private companies react to unprecedented weather conditions and try to keep people cool. In Eugene, Oregon, US track trials were halted Sunday afternoon and fans were urged to evacuate the stadium due to the extreme heat.
Authorities in Portland, Oregon closed streetcars and streetcars until Tuesday due to high temperatures and some districts halted summer school bus service and people braced for the busiest day. hot from the heatwave. And the city’s Parks and Recreation Department closed outdoor pools on Monday, saying it was too hot and dangerous for employees to be outside.
In Seattle, the school district on Monday canceled the summer lunch service in schools “to protect our students, families and staff” so people don’t venture out at noon.
And there were lingering concerns about forest fires in the region which was already facing an epic drought. Fire crews were positioned in advance in areas of high fire risk, and counties and towns in the region have enacted burning bans – in some cases even temporarily banning fireworks. personal for the bank holiday weekend of July 4th.
HOW DID PEOPLE BEAT THE HEAT?
Cooling centers have been opened in public libraries, community buildings, shopping malls and elsewhere so that people can find air-conditioned indoor spaces. Lack of air conditioning is a concern in Seattle, where only 44% of households have indoor cooling, according to U.S. Census figures. That number has actually increased in recent times, as just a few years ago, authorities estimated that only a third of homes in the northwest’s largest city were air-conditioned.
One of the benefits of some parts of the Northwest is access to cooling water – a large river flowing through Portland and Seattle being located between an inlet to the ocean and a large freshwater lake. .
People flocked to the beaches and coastal areas, where temperatures were high but generally milder than in the more inland parts of the region.
WHEN WILL THIS END?
The people of Seattle usually stare at the forecast with highs in the mid-80s and cringe. But after temperatures well above 100 in the region for days on end, that will seem like a relief as forecasters say cooler sea air will begin to moderate temperatures on Tuesday.
“We still have an extremely hot day in the region before the temperatures gradually cool down,” said Pullin, the meteorologist.
