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.
(tdy-Thu), 01/100 PM.
The moderate Santa Ana event was waning early this afternoon with most places within the Santa Ana Wind corridor likely falling below wind advisory thresholds by 3 pm, the expiration time of the Wind Advisory. The break in the wind will be quite short lived as a second moderate Santa Ana event is likely by around noon Wednesday and continuing into early Thursday. Slightly stronger upper level support with this event may bring a bit more widespread 50 to locally 60 mph gusts across prone mountain and foothill areas. Elsewhere, gusts of 30 to 50 mph will be common, potentially extending into the Antelope valley (Wednesday).
Where and when winds drop off the dry air mass will support some of the coolest overnight lows we have experienced this season with lows in the 30s and 40s common on colder nights with a smattering of 20s for the far interior and at high elevations. Freeze Warnings are in place for tonight for the Antelope Valley and Interior San Luis Obispo with a Frost Advisory in place for the Cuyama Valley. If you live in these areas, take steps to protect any vulnerable animals or plants. Additional Frost/Freeze products will likely be needed in the next few days, especially Thursday and Friday mornings, in the wake of the second Santa Ana Wind event.
Near to below normal temperatures will continue through Thursday. Mostly sunny skies will prevail, outside of possible push of low clouds and fog to coastal areas Tuesday night into Wednesday morning ahead of the second Santa Ana wind event.
(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.

For the Outer Waters, moderate to high confidence in current forecast. This afternoon 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 remain below SCA levels Friday and Saturday with a chance of SCA conds on Sunday.
For the Inner Waters north of Point Sal, high confidence in current forecast. Conditions are expected to remain below SCA levels through Friday. 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 to high confidence in current forecast. For the nearshore waters from Ventura to west of Santa Monica, SCA level offshore winds are expected this morning into Tuesday morning. However, there will likely be a brief lull in winds for a few hours late this afternoon. There is a 30% chance of another round of offshore winds for this same area Wednesday night through Thursday morning. Otherwise, winds and seas are expected to generally remain below SCA levels through Friday.

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 (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 each day.
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.
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.
