Wider weather episode

A series of storms along an atmospheric river of moisture produced a period of heavy rain from March 13 to March 15. Rainfall totals of 3 to 6 inches was measured for many areas of Northwest Oregon and a few local spots had over 7 inches of rain. The prolonged period of rain allowed the saturated soils to make large trees vulnerable to top over if any winds developed (which did happen). No flooding was reported from this rain, but a mudslide did impact a residence in the west hills of Portland.
