The steadiest rain will dampen the Pacific Northwest and northern California Tuesday night, so the rain will not lead to flash flooding. Motorists should still plan on slower travel along Interstate 5.
Treacherous conditions are expected on the roads through the Cascades and Sierra as 3-6 inches of snow falls.
The rain will reach central California late Tuesday night but will weaken in the process. In fact, the band of rain will diminish so much that Southern California can expect dry weather on Wednesday.
Wednesday, however, will not be entirely pleasant in Southern California. Parts of the area will have to contend with gusty winds, the strongest of which will blow along the coast and over the deserts.
The winds may also whip through the Grapevine section of Interstate 5 late Wednesday, posing a danger to motorists. The winds will then shift to a more typical Santa Ana wind fashion Thursday morning.
