Synopsis A storm system will bring a brief period of moderate
rainfall to northern humboldt and del norte counties overnight,
otherwise the vast majority of northwest california will only see
some light rain tonight into Saturday. A few showers may linger
into Sunday. Dry conditions will return for all of next week.

Discussion A storm system will bring another round of rain to
northwest california tonight into Saturday. The heaviest rain is
expected to fall in del norte and northern humboldt counties with
the front washing out rapidly as it moves south and east. Rain
totals may approach an inch in portions of del norte county before
all is said and done while areas of eastern trinity and southern
mendocino counties could see only a few hundredths of an inch or
no rain at all. Winds will generally remain light with only a few
gusts into the 20-30 mph range along the immediate coast and in
the near coastal mountains early Saturday morning.

Drier conditions will begin to develop on Sunday, though a few
scattered showers will likely linger through the day in humboldt
and del norte counties. Ensemble guidance is emphatic that a
highly amplified ridge will begin to develop over the eastern
pacific early this week and extend into next weekend. As this
ridge builds temperatures will gradually warm and the atmosphere
will dry out. By mid next week we will once again be looking at
the potential for fire weather concerns with model guidance
hinting at another offshore wind event. At this time it looks
weaker than last week but this will definitely be something to
watch closely as the models get a better handle on the small scale
details. Rpa

Aviation Visibility was variable during the day at the coastal
terminals from radiative cooling, residual moisture, and light
winds along with mist from the surf. Precipitation in the form of
rain or drizzle is expected later today and tonight at kcec and
kacv. Kuki remains inVFR conditions with cloud heights from
10000 to 25000 foot range and over 6 miles of visibility
throughout the evening. Eys

Marine A large northwest swell continues to propagate through
the waters. Seas will remain above 10 feet through Saturday night
at which point the small crafts will finally be allowed to expire.

Otherwise winds will be fairly light through the weekend with only
a brief period of moderate southerly winds ahead of a quick moving
cold front Saturday morning. A few gusts to 25 kt will be possible
in the northern waters with this frontal passage.

The weather pattern will transition early next week allowing a
strong thermal trough to develop over the interior of california.

This should bring a return to strong northerly winds with the
potential for gales early to mid next week. Rpa

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.
