Marine Weather and Tides
Version 3.4 |
10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 205 PM PST Thu Nov 21 2019
SYNOPSIS. 21/840 AM.
An upper level low pressure trough will continue to bring cool and unsettled conditions as it moves out east today. Offshore winds and a building high pressure will allow for temperatures to increase through the weekend. Then, another storm system could impact the region next week.
SHORT TERM (TDY-SUN). 21/204 PM.
Synoptically, the area is under the influence of a 550DM upper level low that is exiting the region to the east. Another low will cut off from the trof and settle about 700 miles to our west- southwest tomorrow. This system gets pushed to the south of us by a negatively tilted ridge that is pushing into central California from the eastern Pacific, so no real impacts from that other that in the outer waters. The ridge retreats westward on Tuesday making way for a trough that begins its move south. By next Wednesday this is a large and cold system bringing widespread rain and snow to California. Models have it as a closed 546DM upper low over the CWA through Friday at least before it exits to the east.
Enough moisture and instability persisted into today to keep the skies partly to mostly cloudy. There are showers over the eastern San Gabriel mountains, and afternoon showers in other spots of LA County. The negative LIs are to our SE in San Diego's area, so more showers there are certainly possible. Temperatures are around 5-10 degrees below normal.
Weak ridging will develop Friday between the exiting trough and the upstream trough. Temperatures should jump back up to near- normal values and skies should clear to partly cloudy at most. Friday morning could see some dense fog in the Antelope Valley, Cuyama Valley, and near Paso Robles.
Weak to moderate offshore flow will develop over the weekend, peaking between Saturday and Sunday. The NAM forecast for LAX-DAG is down to a -5 on Sunday morning. Our local WRF keeps winds below advisory-strength for now, but the trend has been a little stronger, so that could certainly change by Sunday. Temperatures will climb a few degrees each day with clearing skies and higher heights.
LONG TERM (MON-THU). 21/204 PM.
Warmer than normal conditions will linger into Monday, then models continue to bring a trough of low pressure down the west coast beginning Tuesday. Heights will drop from near 590DM down to near 570DM Tuesday. Temperatures will fall accordingly. By Wednesday morning models indicate widespread precipitation across the CWA and heights dropping down to 550DM or lower. This is a very cold system and by Thursday heights have dropped to an impressively low 540DM over Los Angeles. Snow levels drop to around 3,500 feet by Thursday morning and snow on the Grapevine is a very real possibility.
PoPs have been nudged higher again with this forecast package. In addition to rain and low snow levels, isolated thunderstorms cannot be ruled out. Freezing to sub-freezing temperatures would occur in the interior portions of the area during the overnight hours and downtown LA could drop to the mid-40s.
AVIATION. 21/1759Z.
At 17Z, there was no marine layer or inversion at KLAX.
Moderate confidence in VFR conditions most common today, with SCT025-035 at times anywhere. 20-30 percent chance of BKN025-035 anywhere. No thunderstorm chances. 80 percent chance of LIFR FG at KPRB KWJF KPMD Friday after 10Z, 20 percent chance at KSMX. 60 percent chance of MVFR BKN025 Friday after 08Z at KLAX KLGB KSMO KBUR KVNY, 30 percent chance at KOXR KCMA KSBA. 20 percent chance of -SHRA if those clouds form.
KLAX . Moderate confidence in forecast through 06Z, with VFR conditions except for a 20 percent chance of brief BKN025, and east winds through 19-20Z under 8kt. 60 percent chance of MVFR BKN025 Friday forming by 06-10Z, with a 20 percent chance of -SHRA. High confidence in east winds tonight being stronger than this morning, with a 60 percent chance of reaching 8-10 kt.
KBUR . Moderate confidence in forecast through 06Z, with VFR conditions except for a 30 percent chance of brief BKN025. 60 percent chance of MVFR BKN025 Friday forming by 06-10Z, with a 20 percent chance of -SHRA.
MARINE. 21/1220 PM.
Stronger SE winds are expected on Friday, and could locally approach 25 kt. Moderate confidence in conditions staying below SCA Friday afternoon through Sunday morning. NW winds will increase Sunday through Monday or Tuesday. High confidence in Gale Force winds by Monday off the Central Coast, and a 30 percent chance for the western Santa Barbara Channel. NW to W swell will build sharply with these winds, with widespread hazardous seas.
BEACHES. 21/318 AM.
Surf conditions remain at High Surf levels early this morning, but the surf is expected to diminish through the day. So, HIGH SURF ADVISORIES will remain in effect until Noon for the Central Coast as well as the Ventura/Los Angeles coasts and a BEACH HAZARDS STATEMENT will remain in effect until Noon today for the Santa Barbara County South Coast. Although surf will subside this afternoon, rip current activity will likely remain strong and dangerous through this evening.
LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.
.HAZARD POTENTIAL OUTLOOK (SUN-THU).
Gusty north winds possible in some areas Monday into Tuesday morning. Cold temperatures along with rain and mountain snow is possible Wednesday into Thanksgiving.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
