Crescent City, 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.

Synopsis for the southern oregon coastal waters..North winds have lowered and expect continued light winds and seas today into Thursday. A low will move south of the area towards the central california coast on Thursday and winds may become light and variable at times, especially over waters south of cape blanco. Behind the low, a thermal trough will develop along the coast and north winds and seas will gradually increase over the waters late Friday into the weekend. This may bring gusty north winds and steep seas to the waters south of cape blanco this weekend. Strong north winds and steep wind-driven seas may return to most of the waters early next week.

area forecast discussion
national weather service medford or
337 am pdt Wed may 23 2018

Discussion Current radar observations are showing ground
clutter across much of the nearby radar beam. Satellite imagery is
showing that the marine layer has brought in low clouds to the
coast all the way to the coastal mountains. Otherwise, there are a
few patches of clouds all around the forecast area. This trend is
expected to continue.

Temperatures today will be 5 to 10 degrees lower than they were
yesterday, but healthy CAPE and lis will allow for thunderstorms
to become a bit more widespread than they were yesterday. The
highest chances for showers and thunderstorms will be along the
higher terrain, particularly across the cascades, siskiyous, and
warner mountains; but storms will be possible anywhere west of
the coast.

This pattern is to continue for the next few days. The
probability of any of these storms becoming severe is extremely
low, but the storms could produce occasional lightning strikes and
gusty winds. Meanwhile, the coastally trapped wind reversal is
being strongly indicated by the NAM and should build through
southern oregon by this afternoon. This could bring light drizzle
and fog to those areas.

Later in the week, another low will move eastward into california.

The models are in general agreement of this scenario, and have
been a little bit more progressive as of late. This system will
move out of the area early on Saturday morning. Temperatures will
be near normal on Friday and Saturday.

This change will be a relatively short-lived one and a weak ridge
will build back in over the weekend particularly on Sunday. The
beginning of next work week will return to the ridge pattern of
warmer temperatures and mostly sunny skies. -schaaf

Aviation 23 12z the marine layer is compressed, and we're
currently observing ifr conditions at north bend. Lifr conditions
are possible along the coast, but it has not occurred at the time
of this discussion. As for areas farther inland, the umpqua valley
should see a stratus surge later tonight resulting in MVFR
conditions. As for tomorrow, thunderstorms are in the forecast and
it's possible to see a few of these storms roll over TAF sites
mfr and lmt with partial terrain obscuration if traveling through
clouds. -schaaf czs

Marine Updated 300 am pdt Wednesday 23 may 2018... North winds
have lowered and expect continued light winds and seas today into
Thursday. Seas will become dominated by a west swell of around 12
seconds today, persisting on Thursday. A low will move south of
the area towards the central california coast on Thursday and
winds may become light and variable at times, especially over
waters south of CAPE blanco. Behind the low, a thermal trough will
develop along the coast and north winds and seas will gradually
increase over the waters late Friday into the weekend. This may
bring gusty north winds and steep seas to the waters south of cape
blanco this weekend. Strong north winds and steep wind-driven
seas may return to most of the waters early next week.

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.
