Weather Alert in Washington
Hydrologic Outlook issued August 14 at 12:20PM PDT by NWS Seattle WA
AREAS AFFECTED: Clallam, WA; Grays Harbor, WA; Island, WA; Jefferson, WA; King, WA; Kitsap, WA; Lewis, WA; Mason, WA; Pierce, WA; San Juan, WA; Skagit, WA; Snohomish, WA; Thurston, WA; Whatcom, WA
DESCRIPTION: ESFSEW A frontal system will move across the area Friday into Saturday across western Washington. Through Saturday afternoon, 3-5 inches of rain are expected across the mountains, with 0.5-1.5 inches expected through the lowlands. Very dry antecedent conditions has left the area soils dry and hard. This amount of rainfall in one storm will not have much time to soak into the very dry soil, which will result in heavy surface runoff. Impacts are uncertain due to how much moisture will be able to be absorbed by the soil. Several different threats are expected with this storm, which are detailed below. *Urban and urban-like flooding will be possible in flat areas and roadways. *Some small streams and creeks may become swollen due to rapid runoff while others may remain lower if the channel bed is able to absorb the water efficiently. *Rivers will not flood, but will undergo rapid rises to unusually high levels for this time of year, some of which may reach daily record crests. This will pose a threat to those engaged in recreational activities in and along river channels. *Burn scars will have the potential to undergo impacts, but the probability is low. Impacts may include flash flooding, debris flows, rock falls, and other falling debris. *Those engaging in recreational activities in the mountains may face challenges to where high water may make forest roads and trails difficult to traverse. Please monitor the latest forecasts from the National Weather Service for additional information.

Freezing rain is a condition where precipitation which has fallen in the form of
water droplets reaches temperatures which are below freezing and freezes upon
coming into contact
with surface objects. The result of this precipitation is a glaze of ice which
can be damaging to plants and man-made structures. A severe onset of freezing
rain which results in a very thick glaze of ice is known as an ice storm.

Next Topic: Hole Punch Clouds
Hail is a form of precipitation which is recognized by large solid balls or
clumps of ice. Hail is created by thunderstorm clouds with strong updrafts of wind.
As the hailstones remain in the updraft, ice is deposited onto them until their
weight becomes heavy enough for them to fall to the earth's surface.
Hail storms can cause significant damage to crops, aircrafts, and man-made structures,
despite the fact that the duration is usually less than ten minutes.
