Seattle could get another light coating of snow and ice Tuesday morning, much like today.

The National Weather Service now expects low temperatures Tuesday to be around 33 in Seattle and 30 in Tacoma, with possibly an inch of snowfall.

Rain later today might turn to ice in some parts of Seattle and its suburbs, where temperatures will be right around the freezing mark, said meteorologist Johnny Burg.

Across Puget Sound, a winter storm watch has been issued for Hood Canal, where wet, cold air will be hemmed in by winds from the east-northeast, Burg said. Snow could be 6 inches deep around the canal, Kitsap Peninsula, and points south such as Shelton.

Sunbreaks are reaching Seattle this afternoon, but Tuesday afternoon will be all clouds, Burg said. Tuesday high temperatures should reach the upper 30s to low 40s, and rain is likely.

The skies are expected to become dry by Wednesday, he said.

Seattle-area residents woke up to snow this morning, with amounts varying from a trace to as much as 2or 3 inches in some neighborhoods, which made for a slushy commute.

Among the commute woes was a traffic accident on the Highway 520 bridge involving a bus, which blocked at least one westbound lane until 7:44 a.m.

On Monday, buses had problems on Seattle’s Queen Anne Hill and Bellevue’s Somerset Hill, and some buses in the north and east county operated with chains.

The slushy snow prompted some school districts to delay opening, including Seattle schools, which announced a two-hour delay.

King County Metro Transit hasn’t announced any service changes yet for Tuesday.
