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 Hot and dry conditions will continue through much of
the upcoming week. Winds will subside tonight, and lighter winds are
expected for much of next week as well.
Short term Through Tuesday night. Only one change of note to the
forecast today. Very shallow low level moisture was surging
northward across the far southern colorado river valley and into the
lower elevations of riverside county on southerly winds. Raised dew
points somewhat in the river valley from about bullhead city
southward for tonight and tomorrow. Elsewhere, the excessive heat
warning was working out well today and will probably be allowed to
expire this evening as temperatures come down a few degrees
tomorrow. Red flag warning was marginal, but this was expected, and
will let it ride as well. After briefly lowering on Sunday,
temperatures will come back up a few degrees Monday and Tuesday, but
at this time, it does not look hot enough to support another
excessive heat warning.
Long term Wednesday through Saturday
a pacific trough will continue to dig south into the area midweek
onward, and bring a slight change to the weather pattern. Overall,
nothing of immediate high impact concern sticks out, with dry air
keeping precipitation at bay. Winds will pick up on Thursday as the
trough approaches and the pressure gradient increases across the
great basin. Temperatures will continue their slow downward trend as
well, with highs each day a few degrees cooler than the last.
After Thursday, confidence in the forecast quickly decreases. Long
range models differ on how strong and how far south the main trough
will be, with the GFS considerably stronger than the latest ecmwf.
Based on the overall pattern and the time of the year, favor the|
weaker solution, which would bring some gusty winds and a gradual
decrease in temperatures going into next weekend. The latest runs of
the GFS are trending weaker with the system overall, and the
significant temperature drop on the GFS guidance between Thursday
and Friday has slacked and also shows a gradual temperature decrease
towards normal. This matched well with what was previously forecast,
and with confidence in the long range forecast fairly low, didnt
make any major changes to the end of the week forecast.
Fire weather Red flag warning remains in effect for az zone 102
until 8 pm mst, with lighter wind forecast for Sunday. Hot and dry
conditions will persist through the weekend and much of next week,
with minimum humidity readings in the single digits and poor
overnight recovery in most areas.
Aviation For mccarran... Southerly winds will subside overnight,
and could turn northeast for a period of time Sunday before
southerly winds under 10 knots return in the afternoon. The high
temp Sunday will be around 104. No weather or significant clouds
For the rest of southern nevada, northwest arizona and southeast
california... Northerly winds will spread as far south as las vegas
tonight and Sunday morning, with southerly winds persisting in areas
farther south. The southerly winds should spread back across the
entire area by Sunday afternoon, with speeds generally under 20
knots. No weather or significant clouds expected.

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.
