 this height through Tuesday.

 A 5- to 7-foot west-northwesterly (285-degree, deep-water)

 Moderate to fresh (13 to 24 mph) southerly winds along the 
 coastline and increasing clouds are forecast on Tuesday 
 as a low-pressure system develops off the Northern
 California coastline. 

 A 999 millibar low-pressure system and associated
 cold front is expected to move through the Central Coast 
 Tuesday night into Wednesday with fresh to strong
 (19 to 31 mph) southerly winds, rain and a chance of
 afternoon thunderstorms. This system is expected to bring
 colder air with it and snow levels will reached 4,500 feet.

 Rainfall estimates with this system are forecast to range
 between 0.75 and 1.25 inches.

 The long-range models indicate that dry weather along with
 strong to gale-force (25 to 38 mph) afternoon northwesterly
 winds will develop on Thursday and will continue into
