The state, which previously issued information about high temperatures using special weather statement, has issued its first heat advisory.

In the high glare of a summer evening in Fairbanks, Alaska, Ciara Santiago watched the mercury climb. A meteorologist at the National Weather Service office, she had the dubious honor of issuing the state’s first ever official heat advisory as temperatures were expected to hit the mid-80s.

Forecasters said it might hit 85 degrees in Fairbanks this weekend. The Weather Service has changed how it issues warnings there.
