Powerful Pacific System Impacting the West; First Significant Snow for Portions of the East

Power Pacific system will continue to bring significant impacts for Pacific Northwest into northern California the remainder of the week. Dangerous coastal affects, heavy rain, flooding, strong winds, and higher elevation mountain snow continues. Meanwhile, a storm across the east is set to bring the first accumulating snow to many higher elevations of the Catskills into the central Appalachians. Read More >

(As of March 19th, 2010): Elevated river levels are expected to persist throughout much of eastern and northeastern South Dakota and west-central Minnesota.  The James and Elm Rivers continue to experience moderate to major flooding, with the Big Sioux and Little Minnesota Rivers seeing minor to moderate flood levels.  Several tributaries of the main stem rivers remain above flood stage as well -- with additional rises in river levels expected.  Rapid ice jam flooding will continue to be a significant threat through at least the upcoming weekend as well.     

In addition to the river flooding, widespread areal or overland flooding is also ongoing.  Sloughs, ponds, lakes, and other low lying areas will continue to experience water rises with flooding of secondary and county roads imminent.
