SYNOPSIS

01/156 AM.

Warmer temperatures are expected today as offshore flow returns with areas of gusty Santa Ana winds. A cooling trend will develop Tuesday and Wednesday before Santa Ana winds return Thursday with warmer temperatures into early next week.

LONG TERM (THU-SUN)

01/250 AM.

Temperatures will be on the upswing Friday and through next weekend as a 590dam high noses into the eastern Pacific. The high will expand into California early next week and steer storms well east of the western US. This will break the cycle cold storms dropping into the Great Basin and instead push temperatures to at least 3-6 degrees above normal. Looking a little farther ahead into the following week (Dec 7-13) most of the models maintain the ridge over the eastern Pacific with a likely continuation of the same warm/dry pattern through the first half of the month.

BEACHES

01/230 AM.

A long period west-northwest swell will bring elevated surf conditions to Southwest California Tuesday through Thursday morning. High Surf Advisories have been issued across the Central Coast with peak surf heights of 10 feet. Very High Tides of 7 to 7.7 (MLLW) are expected across all beaches.

The combination of the long period swell and high tides could result in beach erosion with isolated minor coastal flooding, especially for west- northwest facing beaches from 4 AM to 11 AM each day.

Beach hazard statements are expected to be issued for all beaches south of Point Conception with future updates, with a 40% chance that a High Surf Advisory will be needed for the Ventura coast. In addition, coastal flooding potential is expected to peak on Wednesday (due to the surf peaking) giving the highest risk of coastal flooding along the Ventura coastline (30% chance).

Tides will be highest Thursday and Friday. With the large tides and another round of swell, beach hazard statements could be extended into the weekend. Please stay tuned to the National Weather Service for future updates as we continue to monitor the situation.
