The two satellite-derived animations above show the daily snow cover across the Northern Hemisphere (left map) and North America (right map) throughout January 2007. By clicking on the images, the change in sea-ice extent across parts of the Arctic (especially the Labrador Sea) can be seen through the month as well as several significant snowfall events across the U.S. and Europe.

More information on significant winter weather and other hazards can be found on NCDC's Hazards page.

The map to the left depicts the snow water equivalent (SWE) as a percent of normal for the western U.S. as of January 31st. Much of Washington and parts of Colorado reported more than 120% of normal SWE for this time of year. Smaller patches of above normal SWE were also reported in Arizona and New Mexico. In contrast, the absence of snow in the Intermountain Basin, the Oregon Cascades and the Sierras is also evident from the map. Additional information on January severe winter weather can also be found on NCDC's Hazards page.
