317 am pdt Sat oct 21 2017

Synopsis
High pressure aloft and surface high pressure over the great basin
will bring areas of gusty northeast to east winds... Especially
below passes and canyons... Very low humidity... And hot weather
this weekend through Tuesday. The most extreme combination of low
humidity... Stronger and more widespread winds... And heat is
expected on Monday and Tuesday. Winds will weaken Wednesday with
cooling spreading inland for Wednesday into next weekend.

Discussion For extreme southwestern california including orange...

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

high pressure aloft off the baja coast will expand northward into
california and strengthen through Tuesday. Surface high pressure
over the great basin will bring locally gusty northeast winds near
the coastal foothills and below passes and canyons today and
Sunday... With more widespread and stronger winds for Monday and
Tuesday. This will bring a strong warming trend through Monday.

Monday and Tuesday are expected to the hottest days for coastal
and valley areas with highs temperatures mostly in the
90s... Except 98 to 106 for inland orange county into the western
inland empire and for the mesas to the western valleys in san
diego county. The beaches will not be quite as hot with high
temperatures mostly in the 80s. Temperatures may not fall below
the 70s Monday night in some of the windier coastal foothill
locations.

High pressure aloft will begin move westward to a position off the
california coast beginning Wednesday with a trough of low pressure
developing over the interior western states for the latter half of
the week. A cooling trend is expected to develop on Wednesday and
extend into Friday and Saturday. The GFS and canadian models are
faster to move this trough of low pressure into the plains on
Friday and Saturday with the ECMWF slower and more amplified over
the great basin and southwest states on Friday before moving it
slowly eastward on Saturday. With these scenarios... The cooling
would be less with the GFS and greater for the ecmwf.

Aviation
210945z... Coast valleys... Areas of low clouds will persist this
morning, with bases 2500-4000 ft msl and tops to 5000 ft msl. Taf
sites could be impacted at times through 18z, but timing is
uncertain. Aft 18z, mostly clear with unrestricted vis. Gusty
northeast winds will develop after 12z and could impact ksna, kont
and ksbd through this afternoon.

Mountain deserts... Strong and gusty northeast winds develop this
afternoon. Winds of 15-30 kt with gusts to 35-45 kt will produce
mdt up downdrafts and llws over and west of the mtns.

Marine
Winds and waves continue to subside this morning. Lighter winds and
calmer seas are expected through next week.

Beaches
A short-period northwest swell from 290 degrees and a long-period
northwest swell from 295 degrees will build through Saturday. This
will bring another round of elevated surf from 3-6 ft and an
increased rip current threat. Although surf lowers somewhat on
Sunday, rip currents will still be a concern. A beach hazards
statement is in effect through Sunday afternoon.

Fire weather
High pressure aloft and surface high pressure over the great basin
will bring areas of gusty northeast to east winds... Especially
below passes and canyons... Very low humidity... And hot weather
for this weekend through Tuesday. The most extreme combination of
low humidity... Stronger and more widespread winds... And heat is
expected on Monday and Tuesday. Winds will begin in the san
bernardino county mountains... The inland empire and santa ana
mountains this morning... Then increase in coverage toward the
coast and spread into san diego county Sunday through Tuesday.

Strongest winds will be during the mornings Monday and Tuesday.

Lowest daytime humidity of 10 to 15 percent today... 5 to 10
percent Sunday... And around 5 percent Monday and Tuesday with
poorest overnight recovery in the windier areas near the coastal
foothills. For today and Sunday areas of northeast winds 15 to 25
mph with gusts to 35 near the coastal foothills and below passes
and canyons. Stronger and more widespread winds for Monday and
Tuesday with areas of northeast winds 20 to 30 mph with gusts to
45 mph. Isolated gusts to 50 mph.

Winds should weaken Wednesday with some cooling and recovery of
humidity with cooling and higher humidity spreading inland for the
latter half of the week.

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

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
