Grab your umbrellas.

The National Weather Service reports that by Wednesday afternoon, Seattle will reach the top 10 wettest Februarys in history, possibly hitting the no. seven spot. And we're only halfway through the month.

Conditions through Thursday will be keeping in that vein.

The National Weather Service issued a special statement that heavy rainfall through Thursday will lead to an increased threat of landslides in Western Washington.

Rainfall of four to five inches from last week has created some high levels of soil moisture, and the amount of rain expected in the next day will put extra pressure on soil stability. The lowlands should expect one to two inches through Thursday.

West Seattle has already seen a mudslide which triggered a power outage and blocked Highland Park Way S.W. near S.W. Holden Street around 5 a.m. Wednesday morning commuters were rerouted around the hillside.

River flooding is expected on the Skokomish River in Mason County, and may be possible on other area rivers. The NWS emphasizes that those flowing out of the Olympics and Cascades should be treated with special caution.

Light freezing rain is expected for the passes through noon, with a half inch of accumulation or less. NWS advises that anyone traveling over the passes through early Thursday should use extreme caution on potentially icy roadways.
