Synopsis
A weak low pressure system off the southern california coast will
keep high temperatures a few degrees below average through Monday
with areas of night and morning coastal low clouds and patchy fog
and drizzle extending into portions of the inland valleys. Mid
level monsoonal moisture to the east and north will bring some
afternoon clouds to the mountains with a slight chance for
thunderstorms for the san bernardino county mountains and adjacent
deserts for Monday afternoon. There will be warming to near
average high temperatures for Tuesday through Thursday... Then a
few degrees above average for next weekend.

Discussion For extreme southwestern california including orange...

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

the weak low pres trough continues just off the coast of southern
california with an unseasonably deep marine layer remaining in
place. Coastal low clouds will develop this evening over the
coastal waters and push inland well into the western valleys
overnight. Low clouds will linger near the coast through late
Monday morning, putting a damper on the eclipse viewing
opportunities there, but away from the coast conditions will be
mostly sunny by the time of partial eclipse in southern
california.

A weak shortwave will swing across SE california Monday afternoon
and could generate a few showers and thunderstorms over our
northern mountains, with marginal mid level moisture there,
mainly affecting san bernardino and riverside counties. Any
convection will quickly die off after dark.

Continued cool with unseasonably troughy pattern along the coast
for much of the new week with temperatures generally settling to
around normal levels.

Some ridging may develop towards the end of the week and into next
weekend, bringing a slight warmup along with a bit of mid level
moisture on a return flow pattern from the se. No weather was
added to the forecast however during this cycle as the chances are
too low at this time.

Aviation
201927z... Coast valleys... Through 21 0000 utc, mostly skc and p6sm
vis. 21 0000-1500 utc, stratus re-developing and gradually pushing
20-50 sm inland again, with bases around 1500-2200 ft msl, tops
around 2200-3000 ft msl, and areas of vis 3-5 sm in the inland
valleys. Forecast marine layer inversion strength of 5 deg c at
21 1200 utc. Gradual clearing of stratus during the 21 1500-1900 utc
time-frame.

Mountains deserts... P6sm vis and mostly skc through Monday morning.

Marine
No hazardous marine weather is expected through Friday.

Beaches
A 3 ft 14 sec period southwest swell from 200 degrees will continue
today, producing surf of 3 to 5 ft north of oceanside. Strong rip
currents will accompany the elevated surf. High tides this evening
will peak around 6.7-6.9 feet, possibly leading to minor tidal
overflow of low-lying coastal areas. A beach hazards statement
remains in effect through this evening.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

Sgx watches warnings advisories
Ca... Beach hazards statement until midnight pdt tonight for orange

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.
