It’s not the first instance of unusually high temperatures in Alaska, but using the heat advisory label could help convey the weather’s severity.

When you think of Alaska, you rarely think of heat. But currently, parts of Alaska are under the state’s first official heat advisory. Here’s why it is technically new, but not necessarily unique in what’s considered the nation’s coldest state.

Juneau’s record-high temperature is 90 degrees, set in 1975, which would not meet the criteria for a heat alert under historical Lower 48 standards, according to the weather service announcement. However, locally defined criteria has been established for part of the U.S. in recent years.
