Synopsis Isolated shower activity is forecast for northwest
california on Sunday with multiple storm systems then bringing wetter
weather to region for Monday and Tuesday. Lingering chances for rain
then remain in the forecast for Wednesday and Thursday with high
pressure taking control of the forecast by Friday.

Discussion Wet weather is forecast for the start of the week with
Sunday's forecast calling for isolated showers across northwest
california. The best chance for precipitation will be focused over
del norte and humboldt counties during the daytime hours. A series
of storm systems will then begin their decent towards northwest
california come tonight as zonal flow will allow them to slide over
the region. This will bring widespread moderate rainfall to the cwa
with 0.50 to 3.0 inches of rain accumulating across del norte and
humboldt counties while trinity and mendocino counties generally see
around 0.50 inches of rain or less. Gusty winds will also occur at
this time frame, however, they are not projected to reach wind
advisory criteria. The good news is, especially for those who are
ready for summer, that rain chances will diminish from south to
north on Wednesday and Thursday. High pressure will then take
control of the forecast which should lead to pleasant conditions for
the weekend and perhaps even into the beginning of may. /kar

Aviation GenerallyVFR conditions expected for much of
nw ca over the next 24 hours as another rain producing system
remains well off the coast. Toward the end of the TAF cycle
winds will turn to the south and southeast ahead of the approaching
front. Coastal terminals may see periods of MVFR conditions after
midnight tonight (sun night) as CIGS lower... With the potential of
MVFR vsbys higher during frontal passage around sunrise on Monday.

Marine Winds over the coastal waters should remain out of the
west or southwest today before turning to south tonight. These winds
will strengthen to small craft levels over the northern outer waters
late tonight and continue into Monday as an approaching storm system
impacts the pacific northwest. This system is not especially strong
with only a brief period of gusty southerlies occurring around
sunrise on Monday. Winds will then shift back to the west and
diminish. A westerly swell in the 10 to 15 second range will persist
through much of the upcoming week. Wind waves will also build in
response to passing frontal systems Monday... Followed by small craft
seas associated with the longer period swell Wednesday and Thursday.

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

Northwest california coastal waters... Small craft advisory from 11 pm this evening to 11 am pdt Monday
for pzz470.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
