Synopsis
High pressure aloft and surface high pressure over the great basin
will create gusty santa ana winds and hot weather into Tuesday.

Winds and high temperatures will begin to lower on Wednesday, with
above normal highs expected into early next week. Low clouds and
fog will return to the coast this weekend.

Discussion For extreme southwestern california including orange...

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

hot and very dry weather will continue through mid-week with
upper-level ridging aloft and surface high pressure over the
great basin. H500 heights will peak around 595 dm through
tomorrow over southwest ca. This will create high temperatures
around 10 deg above normal for desert and mountain locations. The
downsloping santa ana winds will help create highs 15 to 25 deg
above normal for coastal and valley locations through Tuesday.

Several high temperatures records are expected to be broken or
tied over the next few days. Please see our weather story on our
webpage for the specific temperatures and record information. An
excessive heat warning will continue for the coasts and valleys
through Tuesday for highs in the low 100s inland, and the mid-80s
to mid-90s at the beach.

Gusty northeasterly winds will continue through Wednesday
afternoon in the mountains, valleys and over most of orange
county. Sustained winds of 15-30 mph with gusts of 40-60 mph are
possible through the period, with strongest winds developing
Tuesday morning though mountain passes and along coastal mountain
slopes. A wind advisory remains in effect through the period.

A red flag warning also remains in effect through Wednesday
evening for extremely low relative humidity in the single digits,
gusty northeasterly winds and hot weather.

The ridge aloft will weaken through the end of the week, but
remain over the region. High temperatures will lower to just above
seasonal normals by Saturday. Returning onshore flow will
increase humidity across the coast and valleys by the end of the
week, and also create the possibility of low clouds and fog along
the immediate coast.

Aviation
232015z... Clear with unrestricted vis through Tuesday. Areas of
northeast winds 15-25 kt and gusts 35-45 kt will occur at times,
strongest Tuesday morning. Strongest winds will be through and below
the passes and canyons, and on coastal mountain slopes and
foothills. This will produce mdt-stg uddfs and llws over and W SW of
the mountains. This will impact vcnty kont, ksbd, kral and ksna at
times. Surface northeast winds will be most likely at those airports
Tuesday morning, though kont will continue to be northeasterly at
the surface at times this afternoon and tonight as well.

Marine
No hazardous marine weather is expected through Friday.

Beaches
A combination of west-northwest and south swells will bring mostly 3-
6 foot surf at the beaches of orange county and san diego county
through Wednesday, along with a high rip current risk.

Fire weather
High pressure aloft and surface offshore flow will create critical
fire weather conditions for areas over and west of the mountains
through Wednesday. Northeasterly wind gusts of 40-60 mph are
possible for portions of the mountains, valleys and areas of
orange county, with strongest winds occurring Tuesday morning
along coastal mountain slopes. Minimum relative humidity will be
in the single digits for most areas, with poor overnight recovery.

High temperatures will range from 10-25 deg above normal, as well.

A red flag warning remains in effect through Wednesday evening.

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.
