Synopsis for northern california waters..Northerly winds will continue to increase today as pressure gradient tightens over the waters. The northerly winds will persist through middle of next week as the east pacific high anchors over the area. As a result a northerly wind wave component will develop. However...a separate westerly swell will remain in our waters as well.

Synopsis Building high pressure off the west coast will bring
drier weather to the coast and warmer temperatures to the
interior. Spring time northerly winds will be observed along
the coast during the afternoon and early evening periods. The
drier weather is expected to persist into next week.

Discussion Spring like weather finally arriving to northwest
ca as a fairly strong ridge of high pressure builds over the
eastern pacific. The overall trend this weekend into early next
week is for warmer temperatures, dry weather, and even sunny
skies across northwest california. Typical gusty northerly winds
are also expected along the coast during the afternoon and early
evening periods. With 500mb heights reaching near 580dam have
removed the light pops for the weekend and gradually reduced cloud
cover as well. The ridge axis is expected to cross the north
coast early next week and with that some light offshore flow
should also follow. Thus coastal stratus looks less likely.

Aviation Drier weather will lead toVFR conditions across
northwest california today. Models try to hint at lowering ceilings
for coastal terminals for tonight and tomorrow morning. Have kept
vfr conditions in the forecast for the time being as confidence
isn't terribly high in MVFR conditions for the later part of the
forecast period.

Marine Forecast remains on track this morning with high pressure
taking over the forecast. The pressure gradient will be tightening
over the waters for the next couple of days thus wind speeds will be
increasing. 25 to 30 kt gusts will become common by across the
waters by Thursday evening and then persist through the weekend. A
fresh northerly sea component will develop during this time frame
with 3 to 5 second period.

Additionally, there will be a mid period westerly swell that lingers
in our waters.

Eka watches/warnings/advisories
Ca... None.

Northwest california coastal waters... Small craft advisory from 6 pm this evening to 3 am pdt Saturday
for pzz450-470.

Small craft advisory until 3 am pdt Saturday for pzz455-475.

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.
