No frost yet for Juneau

The growing season can grow a little more

Juneau came close Wednesday night, but the first frost of the season is still out in the cold.

The National Weather Service issued a frost advisory for the Juneau area Wednesday, but by Thursday morning, no frost was observed. Temperatures did fall to the 35 degrees typically associated with frost, said National Weather Service Meteorologist Edward Liske.

“We came close,” Liske said. “It got down to about 37 degrees here at the back of the valley,” he told the Empire. The National Weather Service’s Juneau office is located on Mendenhall Loop Road near Mendenhall Glacier.

The season’s first frost is significant, Liske said, because it indicates that growing season is starting to come to an end. Frost can cause damages to leaves and affect plant growth.

Historically Juneau’s first frost has been anywhere between late August and mid-October Liske said. The earliest recorded frost was Aug. 14, 1947 and last year’s was Sept. 14.

Liske said first frost dates have been getting later and later since records started to be kept in the mid-1940s.

The was no frost advisory in the forecast for the near future, Liske said.
