Frost Advisory in effect for parts of western Washington Tuesday morning

Temperatures will dip into the 30s with a Frost Advisory in effect for parts of Puget Sound.

A Frost Advisory is in effect for much of western Washington until 9 a.m. Tuesday as temperatures drop below freezing in places.

The coldest areas will be the South Sound, cities around Hood Canal, the eastern Puget Sound lowlands into the Cascade foothills and most of southwest Washington. 

The National Weather Service (NWS) of Seattle warned the frosty weather would continue into early Tuesday morning.

Sea-Tac Airport recorded a low of 38 degrees at 4 a.m. Tuesday, setting a new daily record low. The previous low of 39 was set in 1946, according to the NWS.

A Freeze Warning is also in effect for several cities east of the Cascades until Tuesday morning.

Early Tuesday brings the coldest temperatures of the season so far. Bring your pets indoors or into the garage.

It's wise to disconnect your garden hose to keep pipes from bursting and harvest any vegetables from your garden that are sensitive to the cold.

After the mostly clear and cold start Tuesday, expect increasing clouds through the morning and afternoon when rain will develop and move inland after 4 p.m. High temperatures will be in the low to mid 50s. A frontal boundary passes through overnight, leaving us in a cool trough of low pressure for improving conditions Wednesday.

Rain chances will be much lower Wednesday, with off-and-on shower activity under partly sunny skies, as highs hit the mid-50s.
