expected around high tide. This may lead to flooding of
parking lots, parks, and roads, with only isolated road
closures expected.

* WHEN...Until 8 AM PST this morning.

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

* WHAT...Flooding caused by excessive rainfall continues.

* WHERE...Portions of northwest and west central Washington,
including the following counties, in northwest Washington,
Clallam, Island, Jefferson, Kitsap and Skagit. In west central
Washington, King, Pierce, Snohomish and Thurston.

- At 158 AM PDT, Doppler radar and automated rain gauges
indicated heavy rain due to thunderstorms. Minor flooding is
ongoing or expected to begin shortly in the advisory area.
Between 0.3 and 1.5 inches of rain have fallen.
- Additional rainfall amounts up to 0.5 inches are expected
over the area. This additional rain will result in minor
flooding.
- Some locations that will experience flooding include...
Seattle, Tacoma, Bellevue, Everett, Kent, Federal Way,
Auburn, Marysville, Edmonds, Bremerton, Puyallup, Arlington,
Port Townsend, Sequim, North Bend, Belfair, Gold Bar,
Carnation, Darrington and Index.

* WHAT...Hot conditions with temperatures in the mid 80s to low 90s
expected. This will pose a moderate to isolated major risk of
heat-related illness.

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

* WHEN...Until 9 PM PDT this evening.

* IMPACTS...Heat will significantly increase the risk of
heat-related illnesses for those who are sensitive to heat,
especially those without effective cooling or adequate hydration.

* ADDITIONAL DETAILS...Areas of elevated smoke and haze are expected
to remain over western Washington through Friday. This could
result in slightly lower temperatures than forecast.

* WHAT...Hot conditions with temperatures in the mid 80s to low 90s
expected. This will pose a moderate to isolated major risk of
heat-related illness.

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

* WHEN...Until 9 PM PDT this evening.

* IMPACTS...Heat will significantly increase the risk of
heat-related illnesses for those who are sensitive to heat,
especially those without effective cooling or adequate hydration.

* ADDITIONAL DETAILS...Areas of elevated smoke and haze are expected
to remain over western Washington through Friday. This could
result in slightly lower temperatures than forecast.

* WHAT...Hot conditions with temperatures in the upper 80s to low
90s expected. This will pose a moderate to isolated major risk of
heat-related illness.

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

* WHEN...From noon Thursday to 9 PM PDT Friday.

* IMPACTS...Heat will significantly increase the risk of
heat-related illnesses for those who are sensitive to heat,
especially those without effective cooling or adequate hydration.

* ADDITIONAL DETAILS...Areas of elevated smoke and haze are expected
to move over western Washington Thursday and Friday. This could
result in slightly lower temperatures than forecast.

* WHAT...Hot conditions with temperatures in the upper 80s and 90s
expected. This will pose a moderate to major risk of heat-related
illness.

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

* WHEN...From noon Friday to 10 PM PDT Monday.

* IMPACTS...This level of heat will significantly increase the risk
of heat-related illnesses for much of the population, especially
those who are heat sensitive and those without effective cooling
or adequate hydration.

* ADDITIONAL DETAILS...Temperatures will remain well above normal
next week with only gradual cooling expected.

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.

* WHAT...Minor coastal flooding expected. Inundation of 1.5 to 2.5
feet above ground level is possible along shorelines and low-
lying coastal areas.

* WHERE...Tacoma Area and Seattle and Vicinity zones.

* WHEN...From 4 AM to 10 AM PDT Tuesday.

* IMPACTS...Minor coastal flooding due to tidal overflow is
expected around high tide. This may lead to flooding of parking
lots, parks, and roads, with only isolated road closures
expected.

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.
