SYNOPSIS

13/127 PM.

Seasonal June conditions will continue through the next week as at least weak to moderate onshore flow continues, with night through morning low clouds and fog across most coastal areas. Near to slightly above normal temperatures will continue through early next week, with minor afternoon heat impacts, before cooling down during the middle of the week.

LONG TERM (WED-SAT)

13/128 PM.

Tuesday will likely be similar to Monday if not a degree or two warmer and may be the warmest day through the next week, with above normal temperatures away from the coast.

A slow-developing trough 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

14/0234Z.

At 0018Z at KLAX, the marine layer was 900 ft deep. The top of the inversion was near 1700 ft with a temperature of 23 C.

High confidence in VFR TAFs for KPRB, KPMD, & KWJF.

Moderate to low confidence in remaining TAFs. Timing of CIG/VSBY restrictions may be off +/- 2 hours and flight minimums by one category. Lower confidence in visibilities, which could be as low as 1/2 to 1 SM at times.

KLAX...Moderate confidence in TAF. IFR CIGs 005-009 should arrive around 14/01Z. CIGs should lift mid-morning tomorrow (MVFR 010), with low confidence if clearing occurs or intermittent CIGs remain thru end of fcst period. No significant east wind component expected.

KBUR... Moderate confidence in TAF. High confidence in VFR conditions through 14/08Z. 30-40% chance of LIFR CIGs 14/12Z-16Z.

MARINE

13/821 PM.

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 NM or less is possible each night to morning through at least Monday.

BEACHES

13/824 PM.

A couple of long period southerly swells (14 seconds and 18 seconds) will continue to affect the coastal waters through early next week. A Beach Hazard Statement is in effect 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 along south exposed coasts, along with potential for sneaker waves. Even as tides lower, another couple of southerly swells will move into the waters, which could extend concerns into Wednesday night or Thursday. Stay tuned for updates and refer to CFWLOX for additional details.
