The power outages differed sharply across the state as more than 90 percent of the CL&P customers were without power in Plainville, Suffield, Marlborough, Kent, Cornwall and Goshen. All customers lost power in Redding, Ashford, Bolton and Union.


 Warming centers opened throughout the state to offer those without heat some relief, while hotels with power were inundated with customers.


 The Hartford Marriott was completely booked Sunday night, and director of hotel operations Robert Smith said the staff spent the day scrambling to help people find available rooms in other hotels, some as far away as Rhode Island.


 “We are extremely busy with the storm — we have a lot of empathy for the folks coming in because of the power loss,” Smith said. “It’s really a tough thing to go through.”


 Connecticut wasn’t alone, with about 3 million people throughout the Northeast without power. In New Jersey, more than 665,000 were without power, according to The Associated Press. The AP also reported more than 560,000 outages in Pennsylvania, 320,000 in Massachusetts and 260,000 in New York.


 The storm was historic in several ways. With 12.3 inches falling at Bradley, it was the largest snowstorm in Greater Hartford history in October — dwarfing any previous storm in the region. An early October storm in 1987 in Norfolk in Litchfield County dropped 9.5 inches in the town that is known as “the icebox of Connecticut.’’


 Butler said that CL&P was working hard to communicate with customers and town officials — a subject that became a source of contention in the aftermath of Irene.


 Another issue that Malloy raised Sunday was cellphone service problems. AT&T has 164 cell sites out across the state and cell service is expected to degrade, he said. The problem is not just power, but cables used to transmit data, he said.


 State officials said that six hospitals lost power and were using generators. They are Mid-State Medical Center in Meriden, Middlesex Hospital in Middletown, Johnson Memorial Hospital in Stafford, Manchester Memorial Hospital, Rockville General Hospital and Charlotte Hungerford Hospital in Torrington.
