Animation: Two systems become one big blizzard
Two low pressure systems merged over New England around midnight (EST) on Feb. 9, 2013. This animation of NOAA's GOES-13 satellite imagery from Feb. 7 to Feb. 9 shows the two systems came together and created a blizzard of historic proportions in New England. On Feb. 9 at 4 a.m. hundreds of thousands of people were without power in Massachusetts alone.
