The Sitka Rocky Gutierrez Airport was closed for several hours Friday when a storm forced rocks and other debris onto the runway.

High winds and heavy seas were blamed for the debris, which stretched across the runway for much of the day, according to the Alaska Department of Transportation and Public Facilities.

“The airport is temporarily closed while ADOT&PF assesses potential damage and begins clearing the debris,” said in a Facebook post Friday.

The debris was eventually removed and flights resumed late Friday night, according to the DOT.

Attempts to speak to Alaska Airlines about flight delays were immediately unsuccessful.
