Update A large area of showers is making its way onshore this
morning, and will spread east over the next several hours. The bulk
of the showers are expected to dissipate as they cross the higher
terrain of the siskiyous and cascades, but not all, so shower
chances will persist for much of the area through this afternoon.

Snow levels should hover just above 5000 feet, but locally lower
snow levels are possible, especially within heavier precipitation,
so some high passes may see some accumulations. For more information
on this and the rest of the forecast, see the previous discussion
below. -bpn

Aviation For the 17 12z tafs... From the cascades west... Areas of
MVFR CIGS and local ifr in scattered showers and low clouds with
higher terrain obscured this morning. MainlyVFR ceilings by this
afternoon. However, some higher terrain will remain obscured in
especially near showers. Areas of MVFR CIGS will return this
evening, persisting through tonight. East of the cascades...VFR
conditions will prevail, but there will be obscuration of higher
terrain this morning. The precipitation will end this morning with
vfr ceilings this afternoon.

Marine Updated 800 am pdt Thursday 17 october 2019... Large and
long period west to northwest swell will build into the coastal
waters today into tonight, resulting in a mix of steep to very steep
seas by this afternoon. Seas will peak between 16 and 19 feet at 15
to 16 seconds before gradually subsiding early Friday. A hazardous
seas warning and high surf advisory have been issued, and bar
crossings will become hazardous.

Small craft advisory winds and seas are expected late Friday into
Saturday associated with a cold front. Strong winds and steep to
very steep seas are possible.

Prev discussion issued 421 am pdt Thu oct 17 2019
discussion... The main band of precipitation with the front moving
through the region has moved east of the cascades, and will continue
to move through the early morning hours. With the cooler air mass
moving in behind the front showers will increase in coverage and
intensity as the combination of increased lapse rates and another
front moving moving into the area. The next front will move onto the
coast early this afternoon, and while there is some instability with
this front, the cooler temperatures below -25c are north into
portland's forecast area and the slight chance of thunderstorms
looks to be from CAPE blanco northward in the coastal waters.

High surf will impact the coast through this evening and a high
surf advisory continues for that area.

The next front moving through tonight has our forecast area in a
favorable left exit region of a +110 kt jet, but the strong
atmospheric river flow that helped bring heavier rain is no longer
feeding in with this front. With this lack of a good atmospheric
river flow the precipitation amounts will be considerably less
than the front moving east this morning, in spite of the favorable
jet dynamics.

The next in the series of fronts moves into the region Friday
night into Saturday. This front is expected to have a good
atmospheric river contribution, and even though the best left exit
region of the jet dynamics will be a bit north of the forecast
area, precipitation rates will be similar to the front that moved
through this morning, but for a slightly shorter duration.

Yet another front moves in early Sunday, and with rising heights
ahead of the front the jet axis is well north of the region, and
the resulting dynamics and heavier precipitation north of the
forecast area as well. Sven

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
