Flooding…Is It Finally Our Turn?

November 20, 2011

Just a moment or two to blog this morning, but what a set of weather maps to wake up to!  For several days we’ve been expecting a frontal zone to set up right over the Pacific Northwest Monday-Wednesday with rain, wind, and mild temps.

Now the last few runs of most of the models have shown this setting up directly over NW Oregon instead of Western Washington.  In fact all the flooding events in the Pacific Northwest the past few winters have been just to our north.  Well now they are showing the flooding rain zone directly over us.  I couldn’t believe my eyes when I saw the 12z RPM rain totals.  A large swath of 6″ plus totals not only in the Coast Range but Salem to Longview in the lowlands get 4″+ as well.  The 12z WRF-GFS shows 5″+ as well in the same general area.   If this actually occurs, it’ll be our most significant flood threat in many years in the Northern Willamette Valley.  I’ll post again late this evening (real late) on my strong wind thoughts as well.
