SEATTLE -- 50 weeks of the year, a forecast for rain would have the locals briefly shrug and then wonder what the stock market was up to.

Not so, this time.

After two weeks of relentless snow and frigid temperatures, rain finally made its return to Western Washington, but we might want to hold off on calling it a triumphant return.

A storm beginning to blow in Saturday has quite a bit of rain -- perhaps as much as a half-inch to full inch of rain. Combine that with all the water captured in the irregularly large snowpack -- nature's little reminder of the last two weeks -- and with temperatures rising a solid 10-12 degrees above freezing, we have a recipe for urban flooding.

A FLOOD ADVISORY is in effect for all areas of Western Washington, a heads up to the potential problems of melting snow plus heavy rain overwhelming storm drains and creating large ponds near homes or on area roadways.

You can help mitigate the problem by making sure your nearby storm drains are clear of slush and debris. Garbage crews are also asking residents to make sure trash containers are cleared of snow and not blocked in by parked cars.

There is also a Flood Watch in effect for basically the Skokomish and Chehalis Rivers for the potential of some minor river flooding due to snow melt and the incoming rain.

In addition, the USGS is also warning of the potential for landslides as the ground is soaked from the snow and then adding heavy rain on top.

Up in the mountains, it's a wintry mix as the snow level bounces right around the pass level Saturday morning -- Snoqualmie Pass was reporting a freezing rain just before dawn -- but it'll change over to snow by midday as the snow level drops from 3,000 feet to 2,000 feet.

Eastbound traffic on the pass was closed for some time on Saturday morning for avalanche control work, triggering backups.

A Winter Storm Warning is in effect for the Cascades and Olympics through early Sunday morning. We're expecting 8-14" of new snow above 4,000 feet, and 5-10" of snow between 2,000 and 4,000 feet. Avalanche danger is increasing as well, and could prompt occasional pass closures for avalanche control.

The rain will briefly taper off Saturday evening, but another storm is coming in quickly on its heels, due in late Saturday night/early Sunday morning and bringing another round of lowland rain and mountain snow.

Long range forecasts bring a storm in here about every other day, with the bulk of the rain on Monday, Wednesday and Friday and showers in between. There is a chance of some fringy wet snow on Sunday night and again on Monday night, especially in the Convergence Zone, as snow levels drop to about 700-1,000 feet, but unlike the last events, any snow would quickly melt and not last the day as highs will still climb into the 40s during the day.
