Snowstorm along the U.S. East Coast

Fifty-seven centimeter (22.5 inches) of snow in Hartford, Connecticut, set a new one-day record. “The storm began developing late on January 11, as a snow-making system that had hit the Southeastern U.S. rode up the Atlantic seaboard and merged with another system crossing from the Midwest.”  The natural-color image above was captured by MODIS on NASA’s Terra satellite at 10 am EST on January 12, as the storm center passed over southern New England.

NYC Mayor Declares State of Emergency Ahead of Snowstorm

NYC. Mayor Bloomberg, who is totally not in Bermuda this time, has declared a weather emergency ahead of the incoming snowstorm. That’s not to be confused with a “snow emergency,” which would have banned cars without snow chains and tires from major roads. The newly created “weather emergency” designation urges New Yorkers to avoid unnecessary driving, and suspends alternative side parking, payment at parking meters, and garbage collection. Source
