SYNOPSIS

17/936 AM.

Warmer temperatures are expected this coming week with some locally breezy Santa Ana winds on Monday. The warmest day will be Wednesday with slow cooling the rest of the week along with a return of night and morning low clouds and fog.

LONG TERM (THU-SUN)

17/1006 AM.

Look for a benign upper level pattern to return Thursday and continue through Saturday. At the same time onshore flow will increase some each day. This will reinvigorate the marine layer stratus and most csts and some vlys will wake up to clouds each morning. Winds will not be an issue. Max temps will fall 3 to 6 degrees across the csts/vlys on Thursday. All areas will see 3 to 4 degrees of cooling Friday. Saturday's cooling of 1 to 2 degrees will bring max temps down into the upper 60s through the upper 70s across the csts and vlys.

AVIATION

17/1817Z.

At 1718Z at KLAX, the marine layer was 4000 ft deep. The top of the inversion was at 5700 ft with a temperature of 11 C.

Good confidence in TAFs for KPRB, KSBP, KPMD and KWJF.

Low confidence for KSMX, there is a 50% chance for no low clouds tonight, and if clouds arrive, 30% chance for IFR conds.

Low confidence in TAFs for KOXR and KCMA due to uncertainty in timing and magnitude of northeast winds. Winds may gust up to 25 kt by 16Z at KCMA and KOXR, and there's a 30% chance for northeast winds remaining below 5 kt at KOXR.

Moderate confidence in the remainder of the TAFs. VFR conds could arrive +/- 2 hr from forecast time.

KLAX...Moderate confidence in TAF. MVFR conds could arrive anytime between 04Z and 08Z. Moderate to high confidence in east wind component 8-10 kt between 06Z-14Z.

KBUR...Moderate confidence in TAF. MVFR conds could arrive anytime between 04Z and 08Z.

MARINE

17/149 PM.

GALE WARNINGS expire after midnight, but dangerous ocean conditions will continue into Monday, especially across the Outer Waters. These conditions could capsize or damage small and large vessels. Mariners should remain in safe harbor.

Winds are expected to decrease below GALE levels tonight, especially for the Outer Waters south of Point Sal. Small Craft Advisory (SCA) level conditions (winds and large, steep seas) are likely (80-100% chance) to follow the GALES into into Monday night.

For the Santa Barbara Channel, GALE force winds will likely be confined to the western portion of the Channel, then winds are expected to drop off rapidly tonight, but lingering steep seas will linger after midnight.

Condition are expected to be below SCA levels for the waters adjacent to the Los Angeles and Orange County coasts.

Much improved conditions are then expected for the rest of the week, with marginal SCA level winds possible each afternoon/evening across the Outer Waters and Santa Barbara Channel.

BEACHES

17/152 PM.

A combination of strong winds, large seas, and moderately high evening high tides may lead to high surf with minor coastal flooding possible into Monday morning. High Surf advisories and Beach Hazard statements have been issued across the entire coastline. Please refer to CFWLOX for more details for your area.

Hazardous surfing and swimming conditions are expected with strong rip currents. Minor beach erosion and minor coastal flooding is possible, mainly during tonight's high tide.
