Synopsis Light rain will be possible from late tonight
through Wednesday evening, mainly across del norte county.

Otherwise, mild and dry conditions are expected to prevail across
the region through the weekend.

Discussion Mostly sunny skies prevail across northwest california
this afternoon as high pressure takes hold over the eastern pacific.

Some mid high level cloud cover will begin to spread into the area
this evening from the north as a weak upper level wave moving
through the top of the ridge approaches and then dives southeastward
across the region on Wednesday. 12 18z model guidance has trended
slightly higher on precipitation chances associated with this
feature, bringing the potential for some light rain to del norte
county and perhaps a few sprinkles as far south as the humboldt bay
region from late tonight into Wednesday evening. Any precipitation
that does fall should be limited to a few hundredths of an inch,
with rain chances quickly coming to an end by Wednesday night. The
upper level ridge will then amplify as the axis shifts eastward
towards the coast for the latter half of the week. This will
support dry conditions and mild temperatures through the weekend.

Meanwhile, increasing subsidence beneath the ridge and light
surface winds will lead to the potential for patchy early morning
fog development for the next several nights, particularly across
the inland valleys. Cb

Aviation High pressure aloft continues to dominate northwest
california, maintainingVFR conditions today and into this
evening. Clear sky conditions and light winds tonight lead to the
possibility of localized fog formation for interior valleys early
tomorrow morning. Ceilings at kcec may drop into MVFR early
tomorrow morning as a very weak front moves through northern del
norte county tomorrow as well. Tdj

Marine Moderate to fresh northerlies will prevail across the
waters through the end of the week, with little to no
precipitation expected. As is often the case in northerly flow
regimes, the strongest winds are expected to occur from cape
mendocino southwards, where winds of between 15 and 25 kt are
expected to generate some moderately steep seas. Otherwise, ocean
conditions will generally remain dominated by a series of long
period westerly swells, the first of which will arrive Wednesday
morning. While small in comparison to some of the larger swells
we've seen this season, these swells will likely bring significant
wave heights to near and even slightly above 10 feet, prompting
the issuance of widespread small craft advisories. Brc

Beach hazards After several consecutive days with very high
astronomical tides, the highest high tides have begun to drop, and
will continue to do so throughout the week. Meanwhile, the
transition of winds to a northerly flow regime has eliminated the
extra storm surge, and as a result, tides should reach very close to
the levels predicted by astronomical charts. This should eliminate
most, if not all, coastal flooding concerns for at least the next
week.

Meanwhile, a series of moderate long period westerly swells will
impact area beaches this week, which may result in an elevated risk
of sneaker waves at various times. Beachgoers are urged to use
caution on area beaches, and maintain a safe distance from the surf
line at all times. Brc

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.
