SYNOPSIS

01/755 PM.

A cooling trend will develop across Southwest California Tuesday and Wednesday as winds shift to onshore. Another round of Santa Ana winds will return Wednesday afternoon into Thursday with warmer temperatures that will persist through early next week.

LONG TERM (FRI-MON)

01/100 PM.

Rain free conditions look to continue well into next week. There is a 50-60 percent chance of a strong ridge building overhead into early next week with weak to moderate Santa Ana conditions at times. In this scenario, widespread highs in the mid 70s to mid 80s would be in play for coasts and coastal valleys. If the ridge is weaker or offshore flow does not materialize (40-50 percent chance), more seasonably warm temperatures (60s and 70s) would be common.

MARINE

For the Outer Waters, moderate to high confidence in current forecast. Through Tuesday afternoon, high confidence in winds and seas below SCA levels. For Wednesday, there is a 30% chance of SCA conditions beyond 30 NM from shore. Winds and seas should mostly remain below SCA levels Thursday through Saturday, with winds increasing to near SCA levels at times, mainly Friday night and Saturday night.

For the Inner Waters north of Point Sal, high confidence in current forecast. Conditions are expected to remain below SCA levels through Saturday. However, nearshore from Cayucos to Morro bay offshore wind gusts could approach SCA levels at times.

For the Inner Waters south of Point Conception, moderate confidence in current forecast. For the nearshore waters from Ventura to west of Santa Monica, weak offshore winds are expected tonight into Tuesday morning. Another round of offshore winds is expected for this area Wednesday night through Thursday morning, with a 30 percent chance of SCA gusts. Otherwise, winds and seas are expected to generally remain below SCA levels through Saturday.

BEACHES

01/806 PM.

A long period west-northwest swell will bring building surf to Southwest California Tuesday through Thursday morning. High Surf Advisories have been issued across the Central Coast (8 to 12 feet) and Ventura coastline (7 feet). Surf heights up to 6 feet can be expected elsewhere. Also, 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 12 PM Tuesday through Thursday.

The Ventura coastline has the greatest overlap of high tides and surf heights on Wednesday. Therefore, a Coastal Flood Advisory has been issued from 3AM to 10AM for enhanced impacts. Please see CFWLOX for more details. However, minor tidal overflow will be possible during times of high tides Tuesday through Thursday in low lying areas near the beach.

Beach Hazard statements have been issued for Santa Barbara and LA County Coastline from Tuesday through Saturday morning. Elevated surf will be highest Tuesday through Thursday.
