Winds should begin to increase Friday into Saturday...peaking Sunday with storm force wind gusts possible. Very steep and hazardous waves will accompany this wind event and mariners should prepare for dangerous conditions at sea. The strongest winds and highest seas will occur beyond 5 nm from shore.
PZZ300 249 Am Pst Sat Feb 23 2019
Synopsis for the southern oregon coastal waters..Relatively calm conditions are expected through Saturday. Waves will steepen during Sunday. These conditions on Sunday may be hazardous to smaller crafts. On Sunday night, a front and approaching low will bring gale force winds and hazardous seas to the majority of the waters. The worst conditions will be south of cape blanco. Winds near coos bay will be below gale force, yet the fresh swell from the gale force winds will spread northward Sunday night into Monday.

Discussion A change to a very active wet pattern with rising
snow levels, and very high snow amounts at higher elevations on
moving into the region. The combination of heavy precipitation
rates and rising snow levels melting lower elevation snow will
cause significant rises in streams, creeks and rivers into early
next week. The main river that is expected to experience possible
flooding is the coquille, currently expected to reach flood stage
Monday night. However, several other creeks will possibly flood,
but are not predicted to reach flood stage at this time.

Current radar, observations and camera images are showing showers
moving in at this time, with snow showing on many cameras in the
cascades. Current observations are in line with expected snow
levels. As the 700 mb flow backs to the southwest during the day,
the 850 mb temperatures slowly rise, and with them the snow
levels also slowly rise during the day. Snow levels are expected
to be around 3500 feet later this afternoon. As the axis of the
110 kt jet slides farther south tonight, the region sits in a very
dynamically favorable right entrance region of the jet in the also
favorably speed divergence area, combining to bring
increased vertical motion over the area. This increased vertical
motion will combine with the first trickles of the atmospheric
river flow that increases through the day Sunday to increase
precipitation rates over the region.

This pattern remains in place into Monday with the front remaining
stalled over the region in the atmospheric river flow with 6 hour
precip rates over the burn scars in SW oregon indicating a possible
concern for debris flows and with observations of log jams in the
taylor creek burn scars some damage to forest roads might also be
possible.

A shift in the indicated path of the low Monday morning into
Tuesday morning focus more of the precipitation to the coastal
ranges from the cascades, but very high snow amounts are still
expected in the cascades, and the increased rain amounts west of
the cascades will increase the chances of flooding in that area,
and the prolonged heavy rates on burn scars will increase the
chances of debris flow and mud slides and forest road damage.

Sven

Aviation For the 23 12z tafs... Rain is occuring along the coast
and that precipitation will push in throughout the day. Expect a
mixture ofVFR and MVFR at most TAF sites. However, MVFR will
become more likely tonight as the air mass moistens.

Marine Updated 200 am pst Saturday 23 february 2019... Relatively
calm conditions will continue into Saturday. A weak front will move
into the area late tonight into Saturday, but winds will stay below
small craft.

South winds will increase to 20 to 25 knots on Sunday bringing
hazardous seas for smaller crafts. The areal coverage of this
hazard will be isolated. The next big talking point will be south
winds increasing further up to gale force strength on Sunday night.

The latest model guidance shows these gale force winds occuring
around and south of CAPE blanco. The model guidance has been
changing, but we felt confident that gale force winds will occur in
the southern water zones sometime Sunday night.

In addition to the gales, the seas are expected to become very steep
with wind wave and fresh swell surging north on Sunday. Eventually,
a front will sweep through the waters Monday and turn winds out of
the west. Seas will still remain hazardous to smaller crafts as
fresh swell moves through the waters.
