Baked Alaska in State’s First Heat Alert

For the first time ever, parts of Alaska will be under a heat advisory — but you can put an asterisk at the end of that term.

It’s not the first instance of unusually high temperatures in what many consider the nation’s coldest state, but the National Weather Service only recently allowed for heat advisories to be issued there. Information on similarly warm weather conditions previously came in the form of “special weather statements.”

Using the heat advisory label could help people better understand the weather’s severity and potential danger, something a nondescript “special weather statement” didn’t convey.

The first advisory is for Sunday in Fairbanks, where temperatures are expected to top 85 degrees Fahrenheit (29 degrees Celsius). Fairbanks has has been warmer in the past, but this is unusual for June, officials said.

Grist:

In Alaska, where hazardous cold is historically more of a concern, weather offices in Fairbanks — just 120 miles south of the Arctic circle as the raven flies — didn’t have the option of issuing heat advisories until the beginning of this month, when it was added to a list of possible public alerts. “It gives us a more direct way of communicating these kinds of hazards when they occur,” Santiago said.

The heat bearing down on Alaska isn’t entirely unprecedented, at least in meteorological terms. On the heels of a cold spring, a dome of high pressure, known as an upper-level ridge, has settled over the Interior, a fairly common pattern that traps warm air. In the state’s central valleys, that can spell high temperatures and dry conditions. Temperatures on Friday reached a high of 82 degrees Fahrenheit. An updated advisory on Sunday warned the hot conditions would last until Tuesday, with “temperatures up to 87F to 89F… Isolated areas up to 90F are possible, especially in the Yukon Flats.”

“People in [the] Lower 48 might think that’s nothing, but here those temps could feel like 110,” Santiago said.
