Special Weather Statement issued May 11 at 4:14PM PDT

Alert Icon Weather Alerts

The NOAA Space Weather Prediction Center has observed extreme (G5)
geomagnetic conditions early Saturday morning and expects severe
(G4) conditions to continue through the weekend.

A geomagnetic storm of this strength can cause multiple and
widespread issues with various power and communications systems.
Widespread voltage control problems may occur, and some power grid
systems may experience component failures, disruption of service,
and protective device trips. This could result in blackouts.

GPS and other satellite navigation may be degraded for days.

HF/VHF/UHF radio propagation may be impossible in many areas for
one to two days.

Low-frequency radio navigation can be out for hours.

Aurora may be visible at much lower latitudes.

Flood Watch issued February 28 at 2:43PM PST until February 29 at 4:00PM PST

Alert Icon Weather Alerts

A strong frontal system moving across the area today will continue
to bring moderate to heavy rainfall to western Washington and
possible flooding.

* WHAT...Flooding caused by excessive rainfall continues to be
possible.

* WHERE...Portions of northwest and west central Washington,
including the following counties, in northwest Washington, Grays
Harbor. In west central Washington, King, Lewis, Pierce and
Thurston.

* WHEN...Through Thursday afternoon.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.

* ADDITIONAL DETAILS...
- A rising snow level, moderate to heavy rain, and to a lesser
degree low- to mid-elevation snowmelt will potentially
produce enough runoff to cause minor flooding of some streams
and rivers. The Olympics and Cascades could see an additional
2-4 inches of rain, with some locally higher amounts
possible. With the snow level having risen to above 4000
feet, expect rises on area rivers. However, there is still a
fair amount of uncertainty on which rivers will flood based
on snow level changes, precipitation type and amount, and
snowmelt.

Special Weather Statement issued January 30 at 2:49PM PST

Alert Icon Weather Alerts

Rainfall of one to five inches over the past few days has increased
soil moisture to high levels across western Washington. Heavy
rainfall of up to 1 to 3 inches is expected through Wednesday,
especially in the higher elevations.

This amount of rain will put extra pressure on soil instability,
leading to an increased threat of landslides.

Two landslides have already been reported in various locations in
western Washington including the Leschi neighborhood in Seattle and
near Union. More landslides are possible.

Special Weather Statement issued January 6 at 4:16AM PST

Alert Icon Weather Alerts

...AFTER A RELATIVELY MILD WINTER THUS FAR, THE POTENTIAL EXISTS FOR
THE COLDEST TEMPERATURES OF THE SEASON JANUARY 12-15, 2024...


An active weather pattern will continue to impact the region
through at least the next week as a series of strong frontal
systems bring additional rounds of lowland rain and mountain snow
to Western Washington. Heavy snow will slowly decrease in
intensity through the Olympics and Cascades this morning as snow
transitions into snow showers. After a brief break Sunday into
Sunday night, prolonged heavy snow is becoming increasingly likely
Monday through Thursday as a series of systems move across the
Pacific Northwest. Current forecast snowfall totals of 2 to 5
feet over 2000 feet will be possible through this timeframe.
Currently, there is a 50-80% chance for 48-hour snowfall totals in
excess of 30 inches over the Cascades above 2500 feet, including
Stevens and Snoqualmie passes. In addition, westerly winds will
increase during this time, with gusts to around 40 mph and even
higher over the high Cascades Tuesday with a 65% chance for peak
wind gusts over 50 mph. Anyone with travel plans over the Cascade
passes and/or through the rest of the Cascades and Olympic
mountains will need to be well prepared for dangerous travel
conditions due to a combination of heavy and blowing snow.

The potential also exists for much colder temperatures across
Western Washington by the second half of the week as a much colder
airmass settles into the Pacific Northwest. Uncertainty still
exists in how cold this airmass will be with disagreement in how
far south high pressure penetrates out of southern Canada.
Currently, there is a 50% chance for the low temperatures to drop
below 20F Thursday night through Saturday night across the
lowlands. After a relatively mild start to the winter season,
these temperatures will come as a drastic change to many. While
the details remain unclear, it is worth monitoring the forecast
for potential changes and additional information over the next
several days.
