Storm Stats: November 10-13 Precipitation & Flood Events

It has been a rainy three days on the North Coast. A front carrying a lot of tropical-origin moisture hit us pretty hard with very intense delivery of rainfall. Wind gusts were mostly below 40 mph, but rainfall was on the extreme-side.  Check out observed precipitation for 11.12.08 as recorded by the Northwest River Forecast Center. Clatsop County received well over 3 inches of rain in most parts–in some areas exceeding 6 inches in a 24 hour period!

Rivers in Tillamook and Clatsop counties crested well above flood stage. The Wilson and Nehalem Rivers are represented in the following hydrographs (courtesy of the US Geologic Survey).  The red line represents the point at which the waters were higher than “flood stage”.  Several smaller streams left their banks. One washed a bridge and some motorists off of a local road in Tillamook County.

The moisture is good, however for farmers who have been wondering how pastures would recover from a relatively dry fall and for salmon stocks just entering the lower reaches of many North Coast streams on their fall runs.
