Anchorage sets record with first 90 degree day

Anchorage, Alaska saw its highest temperature on record Thursday with residents celebrating July 4 subject to 90-degree temperatures, according to the National Weather Service.

"Several locations through southern Alaska saw their single hottest day on record yesterday, and daily record high temperatures are expected there again today," the weather service tweeted Friday, along with a map showing a 90 degree temperature recorded at the city's airport.

Several other locations in the area reported temperatures as high as 89 degrees, which broke the city's previous record of 85 degrees set in 1969.

“A massively large and warm airmass from the surface to over 15,000 feet intensified right over southern Alaska,” a climatologist based in Anchorage told USA Today. “This warm air aloft kept the surface air that was heated by the sun at the ground level.”

"Anchorage is not a warm city. We are not built for 90°F temperatures – just as Los Angeles is not built for 20°F temperatures in the winter," he continued. "We will manage, but most everyone I know is ready for it to be over. I certainly am."

The record-high temperatures forced the city to cancel its annual July 4 fireworks display after the city's fire department issued a "burn ban," warning of the risk of wildfires.

“Just a reminder per MOA Code 14.70.180 it is unlawful to knowingly sell, possess, or use any explosive fireworks or stench bombs to which fuses are attached or which are capable of ignition by matches or percussion, without permission of that municipal official charged with issuing permits for such activities,” the fire department said this week. “Violation of this section shall be punishable by a civil penalty of $300.”
