On Jan. 20, 2012, more than 250,000 customers were without electricity, as utility crews struggled to restore power, according to news sources. Rising temperatures and potential new rainfall raised the possibility of flooding in the days that followed.

Snow still blanketed much of Washington state on Jan. 23, 2012, when the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on NASA’s Terra satellite captured these images. The top image is a natural-color scene similar to what our eyes would see from the sky. The bottom image is a false-color scene that better distinguishes between snow and clouds. Ice and snow are red. Liquid-water clouds are white, and ice clouds are peach. Vegetation is bright green.

Snow blankets the region east of Seattle and Portland, stretching all the way to the Idaho border. In the band of forest along the Pacific Coast, snow may be more prevalent than it appears, as trees sometimes hide it from satellite imagers.

Warmer air blew into the region soon after the storm, adding to hazardous conditions. Flooding closed roads and forced some residents into emergency shelters. On Jan. 23, KVAL reported that a fresh storm was approaching the region and might drop several inches of rain. The National Weather Service issued a flood warning for the Portland area, as the new round of rain had the potential to push rivers into flood stage.
