* WHEN...THROUGH SATURDAY AFTERNOON.
* IMPACTS...EXCESSIVE RUNOFF MAY RESULT IN FLOODING OF RIVERS,
CREEKS, STREAMS, AND OTHER LOW-LYING AND FLOOD-PRONE LOCATIONS.
FLOODING MAY OCCUR IN POOR DRAINAGE AND URBAN AREAS. STORM DRAINS
AND DITCHES MAY BECOME CLOGGED WITH DEBRIS. AREA CREEKS AND
STREAMS ARE RUNNING HIGH AND COULD FLOOD WITH MORE HEAVY RAIN.
LANDSLIDES AND DEBRIS FLOWS ARE POSSIBLE DURING THIS FLOOD EVENT.
PEOPLE, STRUCTURES, AND ROADS LOCATED BELOW STEEP SLOPES, IN
CANYONS, AND NEAR THE MOUTHS OF CANYONS MAY BE AT SERIOUS RISK
FROM RAPIDLY MOVING LANDSLIDES.
* ADDITIONAL DETAILS...
- AN ATMOSPHERIC RIVER IS FORECAST TO BRING PERIODS OF HEAVY
RAIN TO NORTHWESTERN OREGON AND SOUTHWESTERN WASHINGTON
TODAY. THIS SYSTEM OCCURS AT A TIME WHEN AREA RIVERS CONTINUE
TO RUN HIGH AND SOILS REMAIN SATURATED FOLLOWING HEAVY RAIN
EARLIER IN THE MONTH. DURING INITIAL HEAVY RAINFALL TODAY,
THE URBAN AND SMALL STREAM FLOODING THREAT WILL BE MOST
URGENT, ALTHOUGH THE DETAILS OF PRECISE TIMING AND LOCATION
OF THE HIGHEST RISK REMAINS UNCERTAIN AT THIS TIME. AS RUNOFF
WORKS ITS WAY DOWNSTREAM, THE RIVER FLOODING THREAT WILL
INCREASE TONIGHT INTO FRIDAY, WITH NUMEROUS AREA RIVERS NOW
FORECAST TO REACH AT LEAST MINOR FLOOD STAGE. SLOWER REACTING
RIVERS MAY STAY IN FLOOD STAGE INTO SATURDAY AFTERNOON.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

WARNINGS. THOSE LIVING IN AREAS PRONE TO FLOODING SHOULD BE PREPARED
TO TAKE ACTION SHOULD FLOODING DEVELOP.
