Marine Weather and Tides
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

national weather service san diego ca
905 pm pdt Tue mar 20 2018
Mostly dry with passing high clouds and near average temperatures
through Wednesday. Rain should begin to increase in coverage
Wednesday night north of san diego county, with heavier rainfall
expected Thursday. Debris flows near recent burn scars and flash
flooding remain a risk, especially north of san diego county.
Cool and dry weather returns for the weekend.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
at 9 pm pdt... Satellite imagery showed a thick shield of high clouds
over central ca. The southern edge of the cloud band was near the
the mexican border. Farther west... The closed low west of sfo was
shearing apart with decreasing enhancement as ridging held over
socal. The 00z miramar sounding indicated some moistening,
especially in the mid levels, along with stronger westerly flow. The
sfc pressure gradients to the deserts were weakly onshore with
mostly light winds reported.
Radar has indicated weak echoes all evening drifting east over
mainly san bernardino county. Some of these may be releasing a few
sprinkles at times, but remote rain gages indicate any accumulating
rainfall was still well to the NW across far NW los angeles county.
Rainfall reports there were light through 8 pm pdt.
The latest hrrr WRF runs suggest measurable rainfall tonight will be
light, even into Wed morning and mainly over and north of the san
bernardino mts. The latest radar trends support this solution. The
latest (00z) nam12 remains on track for the continuing demise of the
cut-off offshore, and bringing it inland as a weak wave on thu. It
also shows increasing sfc gradients resulting in strong and gusty sw
winds on Thu helping to drive orographic lift over the mts. Some fog
was added to the mts Wed through Thu night. No other forecast
changes were made.
From previous discussion...
for tonight through Wednesday, the closed low off the west coast
will slowly drift eastward, becoming an open wave as it is
incorporated into a larger trough diving south from the gulf of
alaska. As this occurs very little change is anticipated in the
trajectory of atmospheric river (ar). This should keep the bulk of
the rain north and west of l.A. Through at least Wednesday evening.
Any rain that does occur should be light and limited to areas north
of san diego county. For most our region, this period will be
defined by passing high clouds, light winds, near average
temperatures and the potential for nice sunsets sunrises.
Eastward progress of the trough will increase Wednesday night,
allowing the trough axis to reach and sweep through socal by early
Friday. This will finally push the ar south and east increasing the
potential for moderate to heavy rainfall from orange county
southward. Winds ahead of the trough in the surface to 700 mb layer
will turn more southwesterly, and with ample moisture in place,
should focus rainfall amounts along the coastal slopes Wednesday
night. Rain should become more widespread heavy Thursday as the core
of the ar moves through the region. This should be the period of|
time with highest rain rates, possibly reaching 0.50 inches or
higher for periods of time. Urban and small stream flooding remain
possible, with flash flooding and debris flows possible mainly north
of san diego county. Snow levels remain 9,000 ft or above, resulting
in rain even at resort level. Some timing differences exist for the
final passage of the trough axis, though it looks like any rainfall
should end from north to south by late Friday morning. Details on
rainfall amounts rates can be found in the hydrology section below.
Troughing is expected to linger over the west coast this weekend,
resulting in below average temperatures and perhaps a few light
sprinkles drizzle west of the mountains Sunday night.
210340z... Bkn clouds above 9000 feet msl will thicken through
Wednesday evening with bases lowering to 6000-8000 feet msl.
Isolated -shra and some mountain obscurations in southwestern san
bernardino county and northern orange county after 12z Wednesday
through Wednesday evening, with more widespread and heavier rain
holding off until late Wednesday night or Thursday morning.
A storm system will bring periods of rain Thursday morning through
Thursday evening, while higher winds and swell are likely Friday and
Saturday, possibly reaching small craft advisory criteria. Another
much weaker system may bring additional light showers on Sunday.
The greatest rainfall and impacts are anticipated on Thursday...
initially in orange san bernardino county, then southward during the
day across southern riverside and san diego counties. The following
provides details on expected storm total rainfall and rainfall
Forecast rain totals:
orange county: 1-2 inches
inland empire: 1-3 inches
coastal slopes: 3-5 inches, local to 6 inches (san bernardino mts)
san diego county (coast & valleys): 0.25-1.5
inches upper deserts: 0.50-1.5 inches
coachella valley: 0.10-0.50 inches
san diego county desert: 0.10-0.25 inches
hourly rainfall rates:
brief rates near one-half inch per hour possible north of san diego
county, and mainly on the coastal slopes. If these rates were to
develop, it is sufficient for urban flooding and possible debris
flows over and below recent burn areas. This has prompted a flash
flood watch for areas north of san diego county.
Skywarn activation will not be needed through Wednesday.
Sgx watches warnings advisories
Ca... Flash flood watch from Wednesday evening through late Thursday
night for orange county coastal areas-orange county inland
areas-san bernardino county mountains-san bernardino and
riverside county valleys-the inland empire-santa ana

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.
