Rethinking Weather Forecasts

Recently, a professor of statistics at my college said the probability of 115 F (46 C) in Seattle before June 2021 was zero, but it happened. He added at the time there were better odds buying one lottery ticket, and winning.

In my August 4, 2021 post "Gauguin and July 2021," I wrote about "120 Fahrenheit (49°C) [ground surface temperature in Seattle, June 25, 2021, and 121.2 Fahrenheit (49.6°C) air temperature in Lytton, B. C. June 29, 2021] shattering records." Dr. Jason Box was quoted, "That's basically unlivable, at least for nature. [ . . . .] We have to prepare [for] extreme disruptions to our lives."

In my July 23, 2021 post "Climate Reality Pushback" I noted  "More than one billion marine intertidal animals [ . . . ] may have perished along the shores of the Salish Sea during the record temperatures at the end of June, [2021] said University of British Columbia researcher Chris Harley" according to Canada's nationalobserver.com journalist Rochelle Baker." I reminded readers of a heat wave that "killed or harmed three billion animals" in Australia according to a July 28, 2020 bbc.com news article.

In a related matter of extreme heat, Dani Anguiano reported in The Guardian Oct. 21, 2021 about a "California family found dead on hike killed by extreme heat, sheriff says." She wrote, "Temperatures were in the 70s when the family started their hike, but climbed as high as 108F as they made their way through the trail. [ . . . . ] An 85-ounce (2.5-litre) water container the family had with them was empty, and they had no other water. There is no cellphone reception on the trail." 

Here in Washington State, the morning of October 24, 2021, I left the Vancouver area to fish near Mt. Hood when a National Weather Service Emergency Alert cut into the Oregon Public Broadcasting/NPR program I was listening to regarding a Category 5 "atmospheric river" headed just north of Vancouver, Washington that could rip roofs from houses. Before driving, I heard about the threat to northern California and southern Oregon, but nothing about a serious weather warning in my area.

People in northern Clark County, Washington were advised to shelter in lower rooms to wait it out. One person I spoke with said, "The weather people don't know anymore."

Today Monica Garrett, Jason Hanna and Dave Hennen reported about severe weather at cnn.com regarding "A nor'easter drenches the East Coast, spurring flash flooding and water rescues in northern New Jersey." The article noted, "The storm, expected to deliver about 2 to 6 inches of rain in short order over several states, led the governors of New Jersey and New York to declare states of emergency in advance, just weeks after Hurricane Ida left severe flooding there in early September. [ . . . . ] In New Jersey's Union Beach south of New York City, floodwaters trapped some vehicles, and emergency workers made more than a dozen water rescues late Monday into early Tuesday, Union Beach Police Chief Michael Woodrow said. [ . . . . ] [New Jersey] Gov. Phil Murphy delayed the opening of state government offices until 11 a.m. to allow workers ample time to arrive [, noting] 'If you're out on our roads and come across a flooded section, please just turn around -- don't go ahead. Sadly, we lost too many people in Ida who went ahead.'"

Oct. 25, 2021, CapRadio Staff reported at capradio.org "Sacramento sets rainfall record as atmospheric river passes through Northern California." The article noted, "A week ago, Sacramento broke a record of 212 consecutive days without rain. Then yesterday it set a record with more than 5 inches of rain in a single day. [ . . . .] But these sort of extreme swings — from incredibly dry to cyclone bombs and atmospheric rivers — could become more common as climate change warms California."

What next?
