Marine Weather and Tides
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.

Synopsis Winds will decrease tonight while cooler than normal
temperatures will persist through Monday. A warming trend begins
Tuesday with hot temperatures by the end of the week. Dry
conditions will prevail for the week in most areas.
Short term Tonight through Tuesday night...
a large low pressure system over northern nevada continues to
bring windy conditions and below normal temperatures to the
region. Gusty winds over 40 mph are being reported across south
central nevada and northern portions of mohave county and lake
mead. Wind advisory continues for portions of the area through
the early evening. Reg flag conditions have been borderline with
humidity staying above threshold levels in many areas as moisture
from tropical system bud has been slow to exit to the east. For
Monday, relatively cool temperatures will persist with the cooler
airmass associated with the tough remaining in place. Winds will
be lighter, however, as a ridge of high pressure over the eastern
pacific strengthens and pushes the trough north and east, relaxing
the pressure gradient across the desert southwest. Temperatures
will warm a bit on Tuesday bringing high temperatures to near
normal for this time of year.
Long term Wednesday through Sunday...
the long term forecast is shaping up to be hot and dry across the
desert southwest. The main question is, how hot will it get? Strong
high pressure centered just south of san diego is forecast expand
north and east by Wednesday afternoon which is supported by the
gfs ec canadian models. However, by Thursday the models do show some
differences. A trough pushing into the pacific northwest is forecast
to move east and dig across the great basin Thursday and Friday.
However, its the strength of this trough is really the big question.
The ec canadian models show the trough a bit deeper than the gfs
which would help suppress the high and keep temperatures from really
getting excessively hot. However, if the GFS verifies we could be
looking at 110-115 in las vegas and 120-124 in death valley with
temperatures around 115-120 along the river. At this point will not
make many changes to the current temperature forecast and continue
with a wait and see. In either case it looks to be a hot and dry end
of the week across the region. No significant wind is forecast
through the period.
Fire weather Red flag conditions are possible into the evening
hours for southern nevada and northwestern arizona. Winds will
diminish below threshold levels this evening. Dry conditions are
expected through the week with warming temperatures. Winds will
remain light for the week.

kts are expected into tonight with decreasing winds this evening.

For the rest of southern nevada, northwest arizona and southeast
california... Gusty southwest to west winds with gusts 30-40 kts
expected into this evening before diminishing overnight. Lighter
winds are expected on Monday withVFR conditions.&&

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

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.
