    Driving Rain to Douse Seattle to San Francisco

    A rainy day is in store for the Northwest Coast today, with hit-or-miss showers farther inland. Tonight, another round of rain will arrive.

    This latest wave of wet weather will bring heavy rain to the coast tonight through Sunday. Rainfall totals from northern California into western Washington during that time will be on the order of an inch or two, with locally higher amounts.

    The steady, soaking rain could trigger some street flooding, especially in low-lying and poor drainage areas.

    Motorists along the I-5 corridor will face treacherous driving conditions for much of the weekend as the rain pours down. On top of flooding concerns, reduced visibility will be possible in torrential downpours as well as due to spray from other vehicles.

    Howling winds will also batter the coastline tonight into Sunday. Gusts past 50 mph could down trees and power lines or damage buildings.


    Through the end of the weekend, the windswept rain could lead to flight delays at the areas major airports, including Seattle, Portland and San Francisco.

    Temperatures will not be cold enough for snow at pass levels this weekend, but several inches could pile up in the highest elevations of the Cascades and northern Sierra. Hikers venturing into the area despite the storm should be prepared for harsh conditions.

    As this system pushes inland early next week, yet another round of rain will arrive along the Pacific Northwest Coast on Monday. While not quite as intense as this weekend's rainfall, this next storm will still allow damp conditions to persist over the area until the middle of the week.
