Issaquah, WA Weather Alerts

The second of two atmospheric rivers will arrive this evening and
last into Tuesday. Although area rivers are likely to remain below
flood stage, wind has caused tree debris to fall to the surface.
With additional rainfall and wind expected, urban drains may become
clogged, and standing water and minor flooding is possible.

* 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, Mason
and Skagit. In west central Washington, King, Lewis, Pierce and
Snohomish.

* WHEN...Through Wednesday morning.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Creeks and streams may rise out of their banks. Flooding may occur
in poor drainage and urban areas.

* ADDITIONAL DETAILS...

* WHAT...South winds 10 to 20 mph with gusts up to 40 mph.

* WHERE...Portions of northwest and west central Washington.

* WHEN...Until 11 AM PDT Tuesday.

* IMPACTS...Gusty winds could blow around unsecured objects. Tree
limbs could be blown down and a few power outages may result.

First of the two waves of this atmospheric river event has moved
through most of Western Washington. Break in the steady rain today
before the second wave arrives tonight bringing additional rainfall
that will last into Tuesday. Snow levels will remain high. This
combination could push rivers in the watch area close to flood stage
today into Wednesday morning. Rain late tonight into Tuesday may
also lead to localized flooding in urban areas.

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

including the following counties, in northwest Washington, Mason
and Skagit. In west central Washington, King, Lewis, Pierce and
Snohomish.

* WHEN...Through Wednesday morning.

* IMPACTS...Excessive runoff may result in flooding of rivers,

A late season atmospheric river will bring moderate to heavy
precipitation from Sunday afternoon through Tuesday across all of
western Washington. Heavy rainfall rates are possible over the
southwest Olympics, and the Cascades. Total rainfall amounts will
range from 1 to 2 inches in the lowlands, and 2 to 4 inches in the
mountains. Snow levels above 5000 feet will result in most
precipitation falling as rain. This will result in rivers running
unusually high, with the Skagit, Snohomish, Skykomish, White, and
Skokomish Rivers potentially over action stage. The Snoqualmie River
potentially will reach minor flood stage. This may impact any use of
the river flood planes that are normally dry this time of year.
Rivers will crest sometime between Sunday and Tuesday.

The next update will be provided Friday afternoon.

Please monitor the latest river forecasts from the National Weather
Service for additional information.

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.

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.

Heavy rainfall fell through early this morning as an atmospheric
river moved through the region. Sharp rises have occurred on rivers
and streams with the potential for additional flooding on the less
responsive rivers and streams. Heavy rain has ended this morning,
but another round of rain will be focused early on Monday across the
far northern Olympic Peninsula.

Additional rounds of heavy rainfall are expected this week. The
first on Monday night will again be focused on the Olympic Peninsula
and the North Cascades, but may not lead to additional flood
impacts. A more impactful system may arrive around Tuesday evening,
and could bring enough rain to lead to additional flooding,
especially on rivers running high after this weekend's previous rain.

This outlook will be updated by 10 AM Monday.

Please monitor the latest river forecasts from the National Weather
Service for additional information.

Heavy rain fell across much western Washington Saturday night into
early Sunday morning, which, when combined with snowmelt, pushed
several area rivers above flood stage. Additional rounds of moderate
to heavy rainfall will be possible through midweek before a cold
front finally pushes atmospheric river moisture east of the region
late Wednesday into Thursday. With rivers running high, cannot rule
out the potential for additional river flooding with additional
rounds of rainfall.

This outlook will be updated by 8 PM Monday.

Please monitor the latest river forecasts from the National Weather
Service for additional information.

An atmospheric river pattern will develop late on Friday and persist
through early next week. This will result in persistent rainfall
across western Washington with periods of moderate to heavy
precipitation in some areas. In addition, snow levels will also rise
well above 7000 feet through the same period. This will lead to
sharp rises on streams and rivers throughout the area, increasing
the potential for river flooding. Moderate to heavy rain may lead to
roadway ponding and minor nuisance flooding at poor drainage areas.

At this time, the focus for the heaviest precipitation is aimed
across the Olympic mountains and the North Cascades. This may evolve
as the event approaches.

This prolonged period of rainfall would keep the Skokomish River
above minor flood stage for several days, along with possibly of
reaching Moderate flood stage.

In addition to hydrologic impacts, there may also be an elevated
landslide risk this weekend into next week.

* WHAT...Mixed precipitation, mostly freezing rain. Additional
ice accumulations of a light glaze.

* WHERE...Portions of northwest and west central Washington.

* WHEN...Until 6 AM PST early this morning.

* IMPACTS...Plan on slippery road conditions.
