Synopsis Warm dry weather will occur across the region through
Saturday. Light showers will be possible over del norte and
humboldt county on Sunday, followed by another period of warm dry
conditions during early to middle portions of next week.

Discussion Upper heights were increasing across the region
Friday morning as a ridge approached from the west... While in the
low-levels, light north-northeast winds were occurring across
area ridgetops. With the exception of eel river valley fog, clear
skies prevailed, and that will give way to mild sunny conditions
during Friday afternoon... With similar conditions expected during
Saturday. On Sunday, an upper trough is forecast to approach the
area from the northwest. Modest ascent will yield marginal deep-
layer moistening that may be sufficient for light shower
development over portions of humboldt and del norte counties.

Shower activity will quickly exit the region during Sunday
evening, followed by additional upper ridging and large-scale
subsidence. Model guidance shows offshore winds redeveloping at
850 mb during early to middle portions of next week, which will
favor another period of warm dry conditions. Thereafter, an
anomalously cold upper trough may dig over the west coast late
next week resulting in cooler and potentially showery weather.

Aviation Vfr conditions will prevail through the next couple
of days a ridge builds toward the west coast. This pattern will
promote a dry northerly flow across the coast and inland areas.

Periods of breezy gusty n-nw winds during the afternoon and
evening hours through Friday especially along the coast. Some
patchy areas of low clouds will still be possible, primarily over
the interior valleys, during the overnight early morning hours.

Marine High pressure offshore coupled with a trough near the
california coast will maintain fresh to strong northerly breezes
as well as steep waves today. Northerly winds will ease up over
the weekend, primarily north of CAPE mendocino, as a trough
approaches from the nw. Northerly winds and seas will likely ramp
up again after this trough passes over the area. Gale force
conditions will be possible, primarily across the southern waters,
Monday and Tuesday... So a gale watch will likely be need to be
added on Saturday. Also, a mid period NW swell will continue to
subside tonight. Another mid period NW swell will arrive over the
weekend followed by another small NW swell early next week.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until
3 am pdt Saturday for pzz450-455.

Small craft advisory until 9 pm pdt Saturday for pzz470.

Small craft advisory until 3 am pdt Monday for pzz475.

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.
