Marine Weather and Tides
Imperial Beach, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

A deep trough over the west will bring cooler than average weather
and a deep marine layer through Saturday. Areas of drizzle are
possible west of the mountains Friday and Saturday mornings. Gusty
west winds are forecast in the mountains and deserts Friday
afternoon through Saturday. On Sunday the trough will weaken for
warmer days and better clearing west of the mountains Monday and

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

Short term (today through Saturday)
Rain and drizzle were widespread in the san diego and orange county
coastal and valley areas this morning. A rainfall summary has been
headlined on our webpage. The highest amount was 0.15" at bee canyon
in the foothills of the santa ana mountains.

Clearing was very slow today (or nonexistent in some areas) due to a
very thick 3-4kft cloud layer. Skies cleared in the southeast
sections of the inland empire near perris and hemet, but skies
remained mostly cloudy in the orange and san diego county coastal
and valley areas.

A deep trough off the california coast this afternoon will move
inland into central ca Friday. The marine layer will remain very
deep tonight and Friday, and there may be areas of light rain or
drizzle again tomorrow morning. The one change is that cold air
advection aloft with the trough will weaken the inversion through
Friday morning. 850 mb temps of 14c this morning lower to 9c Friday
morning. So despite the deep marine layer, this weaker inversion may
promote better mixing and a greater chance for earlier clearing from
the valleys both Friday and Saturday. The trough and the
accompanying strong onshore surface gradients will bring strong and
gusty west winds to the mountains and deserts Friday and Saturday
afternoon and evening.

It will be cool on Friday and Saturday compared to where
temperatures should be for late may, with high temperatures near the
coast a few degrees below average, and from 10-15 degrees below
average in the valleys, mountains and deserts.

Sunday through Wednesday... The trough over the west fills and
weakens as it moves east over the great basin. The marine layer will
be shallower with higher pressure aloft for less marine layer cloud
intrusion into the inland valleys. The higher heights will also lead
to warmer days.

Beyond Wednesday... A weak trough moves inland along the west coast
Wednesday and Thursday for minor cooling, but it will be much weaker
than our current system and temperatures will be at or just a little
below average for the latter half of next week.

242030z..Coast valleys coastal mountain slopes... Stratus deck with
bases 2000 to 3000 msl and tops to 5000 ft msl persist. May see a
few hours of clearing for inland terminals 22-03z but coastal
terminals likely to retain bkn-ovc conditions. Clouds will quickly
spread back inland 25 03-06z. Overall the cloud deck should be
thinner tonight with slightly higher bases around 2500 feet and tops
around 5000 feet. Patchy fog and drizzle expected late tonight and
early Friday (10-15z). Models indicate faster and more widespread
clearing on Friday with terminals expected to go sct 17-20z Friday.

Mountain crests desert mountain slopes deserts... Winds will be the
primary concern. Expect northwest winds 15-25 kts with a few gusts
25-35 kts possible 21z-06z. This may result in localized llws with
mod uddfs over the mountain crests and into the deserts. Similar
conditions are expected Friday afternoon evening except the gusts
could be a bit stronger.

West northwest winds with gusts near 20 knots are possible Friday
night through Saturday evening. Winds will weaken Sunday into early
next week.

Will extend beach hazards statement through Friday. A long-period
south swell of 3-5 ft 14-15 sec will continue to produce elevated
surf and hazardous swimming conditions through Friday mainly over
orange and northern san diego counties. Sets to 6-7 ft are possible.

Surf will begin subsiding Friday night.

Skywarn activation will not be needed today.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
