Some South Sound areas get early fall frost

VIDEO: First frost of fall season expected Monday morning

People living in Western Washington are waking up to some chilly weather Monday morning.

A Frost Advisory is in effect from midnight to 7 a.m. Monday for areas in the southwest interior, including Olympia, Lacey and Chehalis.

Temperatures are expected to drop into the low to mid-30s, which may result in early frost for the beginning of the fall season.

Typically, frost forms in the south sound and around Olympia on average around October 9, and Seattle typically sees its first freeze around November 14.

The earliest frost reported in Seattle was October 23, 1953 and September 1, 1973 for Olympia.

The advisory also means outdoor vegetation could be affected, as frost kills sensitive plants that are left uncovered.
 
Stevens Pass was hit Friday with its first snow of the season. Six inches fell at the ski resort.
 
On Sunday, the Washington State Department of Transportation reported compact snow and ice at Blewett Pass. Traction tires were advised, and oversize vehicles were prohibited.

Hurricane Ridge Road was also closed Sunday due to snow accumulation and a rockfall, officials with Olympic National Park said in a tweet.

However, Snoqualmie Pass was bare and wet with only a few reports of snowflakes.
