SYNOPSIS

12/524 PM.

Night through morning low clouds and fog will cover most of the coasts and many valley locations through the weekend and into early next week. Highs will cool slightly through Sunday. Most high temperatures will remain above normal, with the exception of the coasts, which will see temperatures near to slightly below normal.

LONG TERM (TUE-FRI)

13/554 AM.

Tuesday will likely be similar to Monday, still warm with above normal temperatures away from the coast.

A trough building will likely build into region Wednesday or Thursday and bring moderate cooling trends away from the coast, drastically reducing heat risk even to warmer interior areas. Night to morning low clouds will likely continue, but expand well into the coastal valleys and possibly some lower foothills.

The associated onshore push will support gusty onshore to northwest winds nearing advisory levels for the interior, possibly extending to southwest Santa Barbara. There may be a period of enhanced fire weather concern on one or both of those transition days (Wed/Thu) for far interior areas and maybe especially at high elevations, which would be situated above the expanding marine layer influence.

AVIATION

13/1251Z.

At 12Z at KLAX, there was a 1400 ft marine layer. The top of the inversion was at 2000 ft with a maximum temperature of 22 C.

High confidence in VFR TAFs for KBUR, KVNY, KPMD, KWJF and KPRB.

Moderate confidence in remaining TAFs. Timing of CIG/VSBY restrictions may be off 2 hours and flight minimums by one category.

KLAX...Moderate confidence in TAF. No significant east wind component expected.

KBUR... High confidence in TAF.

MARINE

13/735 AM.

Moderate to high confidence in current forecast. Conditions are generally expected to remain below Small Craft Advisory (SCA) levels across the coastal waters through the forecast period.

Local gusts could reach 21 kts during the afternoon and evening timeframe across the western Santa Barbara Channel, Santa Monica Basin, and nearshore Los Angeles Harbor into the San Pedro Channel.

Patchy dense fog with visibility 1 sm or less is possible each night to morning through at least Monday.

BEACHES

13/735 AM.

A couple of long period southerly swells (14 seconds and 18 seconds) will move into the coastal waters on Saturday and continue through early next week. A Beach Hazard Statement is in effect from Saturday morning through Monday evening due to elevated surf of 3 to 6 feet on south-facing beaches of Ventura County Beaches, Malibu Coast, Los Angeles County Beaches, and Southern Santa Barbara County Beaches.

Evening tides of 7.5 to 7.9 ft are predicted from Saturday through Tuesday. The combination of the unusually high tides with elevated surf could result in minor to locally moderate coastal flooding for south exposed coasts, along with potential for sneaker waves. Even as tides lower, another southerly swell arrives which could extend concerns into Wednesday night. Stay tuned for updates and refer to CFWLOX for additional details.
