Synopsis Showers will transition to areas of light rain after
midnight as a system approaches the region. A warm front will bring
rain at times Tuesday and Tuesday night. Low pressure will move into
northern vancouver island Wednesday morning with the associated cold
front pushing across western washington. Another trough will give
showers to the area on Thursday. Dry weather is expected on Friday
and possibly for parts of the south interior on Saturday. A weak
front will bring a chance of rain Sunday, with decreasing showers
early next week.

Short term Radar shows numerous showers from the coast and
olympic peninsula extending into the southwest interior and
south/central puget sound. Breezy south winds are occurring over
areas mostly shadowed by the olympics from the north sound to most
of the north interior. Will loss of daytime heating, some of the
shower activity will decrease during the evening. However, warm
advection rain will begin to affect at least north and west parts of
western washington later tonight as a system approaches the region.

Models show a warm front bringing increasing rain through the day
Tuesday. Precipitation will become heavy at times at the
coast/olympics and eventually in the cascades. Snow levels will be
low at the start, near 3000 feet with several inches of snow
possible from late tonight through Tuesday evening. The period of
heaviest precipitation over the cascades should occur after snow
levels rise above pass level, up to near 6000 ft later Tuesday
night. It is possible mount baker could get get 6 or more inches but
the passes should see less than that before changing to rain. Will
hold off on a snow advisory given the switch over the rain that is
expected an uncertainty on whether some higher spots like paradise
will switch to rain before reaching criteria. Motorists should still
anticipate a period of accumulation snow over the passes before the
change over the rain occurs.

The bigger concern is the increased risk of landslides with the next
batch of lowland rainfall. Up to an inch of rain could fall in some
lowlands areas from Tuesday through Wednesday. Will issue a special
statement to address the further elevated risk due to rainfall. Rain
will be heavy at times in the mountains, especially along the south
side of the olympics. The skokomish river in mason county looks to
be at most risk for minor flooding with this event. See the
hydrology section below for details, including the flood watch
issued for mason county.

Winds look breezy to locally windy as a 1006 to 1010 mb low tracks
into north vancouver island by midday Wednesday. Models still
develop a meso low on the northeast side of the olympics, but is
weaker with the gradient compared to past runs due to the further
northward track of the main low. Southerly winds may gust to 40 mph,
especially from central or north puget sound to around admiralty
inlet. The slightly weaker gradient shown by models suggest sub-
advisory winds at this time. Given that soils will be rather
saturated, some localized down trees are still possible.

An upper trough will bring showers to the area Thursday, but
precipitation coverage and intensity will generally be on the
decrease. A puget sound convergence zone could also develop,
bringing a somewhat better chance of rain to snohomish and king
counties. Highs will remain cool in the lower 50s.

Long term Models are in good agreement that Friday will be dry as
an upper ridge builds over the area. The flow will be light and
temperatures should warm up, possibly close to 60. Some rain may
reach the coast and north parts of the area Saturday but much of the
area will be in the warm sector of the next frontal system. Highs
could be even warmer, possibly into the low 60s around puget sound.

If sea-tac does reach 60, it will be the first time this year.

Light rain or showers will eventually reach much of western
washington by Saturday night and Sunday with somewhat cooler high
temperatures. Models have shifted around on the pattern early next
week. Climatology seems the best way to go and have maintained some
chance of showers and near average highs. Mercer

Aviation Scattered showers and partial clearing periods will give
way to increasing clouds overnight as the next front nears the area.

Tuesday will be a rainy day with low cigs. The mountains have been
obscured at times tonight, they'll probably come out this evening,
and then in Tuesday the mountains and foothills will be obscured.

Westerly flow aloft this evening will become southwest flow aloft
and will increase on Tuesday.

Ksea... Scattered showers and clearing periods and then the clouds
increase overnight with another rainy day Tuesday. A southwest
breeze this evening will become more southeasterly overnight, and
then the south wind will pick up again Tuesday.

Marine Another front will arrive Tuesday. Small craft advisories
are in effect for the coastal waters and puget sound but will
probably settle down this evening and then come up again on Tuesday.

On Tuesday small craft advisory strength southerlies are likely for
most waters, and the coast may see a good 20-30kt southerly on
Tuesday. The system on tap for Wednesday is not as strong on the 12z
gfs and suggests that the southerlies could be stronger on Tuesday
than on wed.

Hydrology A warm frontal system will bring 1 to 3 inches to
the cascades and 2 to 4 inches to the olympics Tuesday morning
through early Wednesday morning. While precipitation amounts will
only be moderate, currently saturated soils will cause increased
runoff. Most rivers will see rises, and a few could approach
bankfull on Wednesday.

Precipitation amounts looks sufficient enough to cause minor
flooding on the skokomish river in mason county. A flood watch was
issued for this threat from late Tuesday night through Thursday
morning. The most likely scenario is for minor flooding to develop
on the skokomish river Wednesday morning and continue through
Wednesday night. See the latest flood watch for details.

The additional rainfall will also cause a further elevated risk of
landslides late Tuesday through Wednesday. Soils remain saturated
with the risk already elevated, but rainfall Tuesday into Wednesday
will increase the risk further. Up to 1 inch of rain could fall over
the interior lowlands from Tuesday morning through Wednesday
morning, wit most areas somewhat less. Heaviest amounts over 1 inch
will occur on the coast and over the mountains.

Climate The rain today at sea-tac makes 45 days
with measurable rain since february 1st. Only two years in over 120
years of weather records in seattle have had more rain days in
february and march, 1961 with 49 days and 2007 with 46 days.

Through 3 pm today the combined february and march precipitation
total for seattle is 15.36 inches. This is the second highest total
on record. The record is 15.55 inches set in 2014.

There has been measurable precipitation on 23 out of the 27 days
at sea-tac this month. The record for the most days with
measurable precipitation in march in seattle is 27 days in 1989.

There has been measurable rain every day so far this month at
quillayute. The current rain day streak including this morning is
35 days in a row. The record is 47 days in 1990. Felton/mercer

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.
