Marine Weather and Tides
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.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis Tranquil weather will continue over most of the region
today and Saturday before a circulation along the southern
california coast begins to pull moisture from arizona into southern
nevada late Sunday into early next week. This will lead to a return
of showers and thunderstorms to the region.
Update E-w deformation zone draped across northern inyo county
and central nevada will be the area to watch today. Models showing
slightly better instability today especially over the higher terrain
of far northern lincoln county. The deformation zone still progged
to shift further north, more along highway 50 Saturday. Elsewhere,
dry and warm. No update necessary.

Short term Through Saturday night
little change in the weather can be expected today and Saturday. A
weak circulation near the southern california coast will remain
fairly stationary today and Saturday with only light dry southerly
flow over most of the region. A deformation zone on the northeast
periphery of the circulation will remain draped across the southern
sierra and central nevada. Limited mid level moisture and instability
in this zone will lead to a slight chance of light showers or brief
thunderstorms this afternoon then it will shift farther north on
Saturday. The southern sierra may still see a few showers or
thunderstorms Saturday afternoon. The rest of the region will remain
dry with temperatures climbing a few more degrees today then
leveling off on Saturday.
Long term Sunday through Thursday.
Closed low off the coast of southern california will be the main
influencer of our regional weather through the long term period.
On Sunday, moisture will begin advancing northward on the eastern
periphery of the low, bringing increased chances for thunderstorms
to mainly mohave county and perhaps parts of the spring mountains
and mojave preserve by late in the afternoon. Things get more
interesting (and unfortunate for eclipse watchers) Sunday night into
Monday as deeper moisture advects northward into the eastern two-
thirds of the forecast area. This increasing moisture, combined with
increasingly favorable jet dynamics (both in the left exit region of
300mb jet streak & in the northeast quadrant of the closed socal
low) will promote widespread lift late Sunday night and continuing
for much of the day Monday. This means showers and thunderstorms may
develop overnight Sunday along with widespread cloud cover, and
linger into Monday afternoon, potentially affecting the visibility
of the eclipse Monday morning. I boosted pops into the slight|
chance chance category for much of the region during this time, but
based on MOS trends, this may not be high enough and subsequent
shifts may need to boost pops further during this time period.
Additionally, widespread cloud cover and areas of shower activity
will keep Monday temperatures a few degrees cooler than normal.
Tuesday and Wednesday will also be convectively active with
lingering moisture and instability while the closed socal low still
circulates to our west. Added pops to much of the region for this
time period, mainly excluding the western mojave desert where
overall moisture and instability looks to remain quite marginal.
Confidence decreases Thursday onward as the low will either eject
northeastward and wash out, or push through the mojave desert in a
more compact form. The latter would result in another day of
thunderstorm activity, while the former would tend to promote drier
air pushing in from the west. With low confidence, made few changes
beyond midweek and kept temperatures near normal.
Aviation For mccarran... A typical east-southeast wind component
can be expected this afternoon early evening followed by a light
southwest component overnight. For the most part wind speeds will
remain below 10 knots.VFR conditions can be expected in all
For the rest of southern nevada, northwest arizona and southeast
california... A circulation near point conception with mid-level
moisture and instability extending from near bishop california
across central nevada will lead to isolated high based showers or
thunderstorms this afternoon and early evening. Cloud bases will
generally be 12-15 kft msl. The rest of the region will be mostly
clear with winds generally less than 15 knots.
Fire weather Limited mid level moisture and instability will
lead to a few showers or brief thunderstorms over the southern
sierra and central nevada zones today and Saturday. The rest of the
region will see mostly clear skies and generally light winds. A
circulation along the southern california coast begins to pull
moisture from arizona into southern nevada late Sunday into early
next week. This will lead to a return of showers and thunderstorms
to the region.

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.
