The main concern is coastal areas at this point. However, as these storms are still developing, there is a high degree of uncertainty regarding what their impact will be on inland areas.

...TWO STRONG FRONTAL SYSTEMS BRING THE POTENTIAL FOR HIGH
WINDS AND HEAVY PRECIPITATION TO THE REGION ON MONDAY AND
TUESDAY...
A STRONG UPPER LEVEL LOW PRESSURE SYSTEM WILL APPROACH THE COAST
EARLY IN THE UPCOMING WEEK. THIS UPPER LOW IS EXPECTED TO DRIVE
TWO STRONG FRONTAL SYSTEMS INTO THE PACIFIC NORTHWEST ON MONDAY
AND TUESDAY. DEPENDING ON THE TRACK OF THESE FRONTAL SYSTEMS...THE
POTENTIAL EXISTS FOR VERY STRONG WINDS AND HEAVY RAINFALL TO
AFFECT SOUTHWEST WASHINGTON AND NORTHWEST OREGON ON MONDAY AND
TUESDAY.
THE FIRST FRONTAL SYSTEM IS EXPECTED TO PUSH ONSHORE EARLY
MONDAY...BRINGING A BURST OF HEAVY PRECIPITATION AND GUSTY WINDS.
SNOW LEVELS WILL BE HIGH ENOUGH THAT PRECIPITATION WILL FALL
PRIMARILY AS RAIN EXCEPT IN THE CASCADES AND HIGHER ELEVATIONS OF
THE COAST RANGE. GUSTY WINDS ALSO LOOK LIKE AN
ISSUE...PARTICULARLY ALONG THE COAST AND IN THE COAST RANGE.
THE SECOND FRONTAL SYSTEM IS EXPECTED TO BEGIN PUSHING ONSHORE
DURING THE DAY ON TUESDAY. AT THIS POINT...THE TUESDAY SYSTEM
LOOKS STRONGER THAN THE ONE FOR MONDAY. IF ALL OF THE PIECES OF
THIS STORM COME TOGETHER...THE POTENTIAL EXISTS FOR VERY STRONG
WINDS FOR THE COAST AND COAST RANGE. THERE IS A CHANCE THAT GUSTY
WINDS MAY REACH THE VALLEY AS WELL. THE FRONT MAY STALL OVER THE
REGION THROUGH WEDNESDAY. IF THIS IS THE CASE...FAIRLY HEAVY
PRECIPITATION TOTALS ARE POSSIBLE ACROSS THE REGION. THIS COULD
LEAD TO FLOODING ISSUES IN SOME OF THE FASTER RESPONDING STREAMS
AND RIVERS IN THE REGION.
AT THIS POINT...THERE IS QUITE A BIT OF UNCERTAINTY IN THE
FORECAST FOR EARLY NEXT WEEK. THE POTENTIAL FOR SIGNIFICANT
WEATHER IMPACTS EXISTS...BUT IS FAR FROM CERTAIN.
PLEASE STAY TUNED OVER THE WEEKEND FOR WEATHER UPDATES. VISIT
