Synopsis
A santa ana weather pattern will bring hot, dry weather through
Wednesday with record setting high temperatures. The gusty santa
ana winds and very low humidities will elevate the fire threat.

Cooler Thursday and Friday with a return of weak onshore flow and
a shallow marine layer near the coast.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

and so it begins. The santa ana weather pattern moved into southern
california last night reflected by dewpoints that have fallen
10-20 degrees in the past 24 hours. Dewpoints were in the teens
and 20s in the mountains, and in the 30s in the valleys.

Prevailing santa ana winds from 8-16 mph in the mountains and
passes were gusting to 20-25 mph with stronger gusts in the wind
prone areas like fremont canyon (40 mph), banning (32 mph) and
boulevard (38 mph).

The winds will ramp up tonight and Monday as stronger surface high
pressure (1032 mb) builds over the great basin. Strongest winds
will surface Monday night into Tuesday morning when a 1041 mb high
settles over southern idaho and sets up an 18 mb offshore
gradient from san diego to nevada. Sustained winds of 20-30 mph
with gusts of 55-65 mph are likely in the wind prone areas during
this time. Tue night and Wednesday are looking windier than
previously thought with the surface high holding on longer over
the great basin, so the red flag warnings may be extended for
another day.

The latest WRF and cansac guidance continues to advertise gusty
northeast winds reaching all the way to coastal orange county
Tuesday through Wednesday morning, extending out over the coastal
waters. MAX temperatures in the beach communities will be
unusually high. Record highs are possible at newport beach Monday
(89), and likely on Tuesday (85), and perhaps a bit out of reach
on Wednesday (95).

Winds are projected to be a little stronger than originally
thought, primarily due to the stronger than anticipated surface
pressure pattern. The 850 mb support is also a little stronger
with winds from 25-30 kts on Monday increasing to 35-40 kt Monday
night into Tuesday. There is also weak cold air advection at 850
mb on Monday night. All signs point to the strongest winds Monday
night through midday Tuesday. We expect the winds to becoming
gradually stronger and more widespread late tonight into Monday,
with strongest winds Monday night and Tuesday with gusts to 55-65
mph in the windiest locales. Wednesday there will be dropoff in
wind speeds, but it will still be noticeably windy in the mountain
passes, foothills and valleys.

Thursday and Friday: shortwave energy from the gulf of alaska
moves southeast across the pacific northwest and across the great
basin, breaking down the monster 596 dm ridge in the process. Heights
lower to 585 dm Thursday Friday, and the pressure pattern turns
briefly onshore. But over the weekend a high amplitude ridge
reforms along the west coast for warmer than average weather and
weak offshore flow.

Aviation
221600z... Clear with unrestricted vis through Monday.

Coast valleys... Areas of northeast winds will produce mdt-strong
up downdrafts and llws at times, strongest 18z today through 03z
tonight and again after 15z Monday when winds will be stronger.

This could impact vcnty kont, ksbd, kral and ksna at times, along
with northeast winds 15-25 kt gusting 30-40 kt.

Mountain deserts... Areas of northeast winds will continue through
Monday. Winds will be 15-30 kt gusting 35-45 kt with strongest winds
near ridges and through passes canyons.

Marine
No hazardous marine weather is expected through next Thursday.

Beaches
A short-period northwest swell from 290 degrees and a long-period
northwest swell from 295 degrees will continue to bring elevated
surf of 3-6 ft and strong rip currents today. Highest surf will be
at west-facing beaches of san diego county. The beach hazards
statement is in effect through 7 pm tonight.

Fire weather
Extreme fire potential Monday and Tuesday with the strong santa
ana winds, low rh and very dry fuels. Northeast winds in the
mountains and foothills today will be stronger Monday and
strongest Monday night into Tuesday morning. Wednesday the winds
won't be quite as strong but it will still be breezy windy.

Lowest daytime humidities of 5-10 percent Monday through
Wednesday with poor overnight recovery. Critical fire weather
conditions could continue into Wednesday and the red flag warning
may be extended one more day.

Lighter winds Thursday through Saturday with cooling and some
recovery in humidity spreading inland.

Skywarn
Skywarn activation will not be needed today.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
