SEA/SWELL:

 Today's 2- to 4-foot northwesterly (300-degree, deep-water)
 swell (with an 8- to 13-second period) will remain at this
 height but (with an 8- to 11-second period) through Wednesday.

 A 7- to 9-foot northwesterly swell (with a 16- to 18-second
 period) will arrive along our coastline on Thursday into
 Friday.

 Arriving from the Southern Hemisphere:

 A 1- to 2-foot Southern Hemisphere (170-degree, deep-water)
 swell (with a 15- to 17-second period) will arrive along our
 coastline on Monday into Tuesday.

 ATMOSPHERIC CONDITION:

 Moderate to fresh (13 to 24 mph) Santa Lucia (northeasterly)
 winds on Sunday morning into Friday will keep most of the
 marine low clouds out to sea. 

 As far as temperatures go, we will continue to see cold
 mornings and mild to warm afternoons through Friday.
 However, smoke from the recent wildfires will continue
 to move over the Central Coast through Monday and will
 produce slightly warmer mornings and cooler afternoons. 

 Today and Sunday's high temperatures will reach the mid 70s
 in the North County and coastal valleys. The beaches will
 be mostly in the mid to high 60s.

 Note: Another strong Southern California Santa Ana wind
 event is expected to start Sunday morning and will
 continue through Tuesday night in the Ventura & Los
 Angeles County region.
 
 Note: Periods of gusty Santa Lucia winds combined with
 continued above-normal temperatures and extremely
 dry fuels will keep fire danger very high to extreme
 levels across much of the Central Coast through
 Friday.

 Next Saturday and Sunday should see the return of the marine 
 layer with areas of fog and mist. 

 The long-range models are showing that a low-pressure trough
 may begin to break down high pressure ridge over the west
 next Saturday into Sunday, bringing the potential for cooler 
 temperatures with marine low clouds with areas of fog and 
 mist. This situation will be monitored closely as it appears
 that Thanksgiving Week may bring some precipitation to 
 California. 

 WILDFIRE DANGER RATINGS:

 Today's fire ratings are at extreme levels along the
 coastline, coastal valleys and very high levels in the
 North County.
