MERRIMACK -- Several communities in southern New Hampshire were dealing with widespread power outages and blocked roadways on Tuesday, but most town officials said their municipalities weathered Hurricane Sandy well.

"We are doing alright," said Police Chief Mark Doyle of the Merrimack Police Department. "The storm came in with a lot of impact, but there was so much information out there in advance, and I think there was a lot of preparation that went into it."

There was minor street flooding on Tuesday morning, mostly associated with clogged drainage, according to Doyle, adding some roads were blocked because of downed power lines or fallen trees.

However, Doyle said all major roadways in Merrimack were open Tuesday after a long night of heavy winds and strong rain. The Merrimack Public Library remained open as a charging station for residents needing to plug in their mobile electronic devices.

In Litchfield, Police Chief Joseph O'Brion said his town was also holding up after the storm, which was followed by periods of sunshine and mild temperatures Tuesday afternoon.

Portions of Route 102 and Page Road were closed because of trees in the roadway, and Talent Road was completely cut off, said police. A small fire ignited at 37 Page Road in Litchfield when an oil lamp dropped, but O'Brion said fire crews were already in that area dealing with other problems at the time, enabling them to extinguish the blaze almost immediately.

The public alert system Nixle was incredibly helpful in alerting residents to road closures and power outages, according to the chief, who said social-networking sites were also heavily used by the town to keep citizens well informed during the height of the storm.

In Amherst, about 70 percent of the town was without power Tuesday morning, said Police Chief Mark Reams.

"PSNH will be out in full force," said Reams, who added that about 12 roads were still closed, including portions of Blueberry Hill Road, Boston Post Road, Milford Street, School House Road, Spring Road and other streets.

A generator was utilized at the emergency center for about five hours throughout the storm, and one of the main communication towers in Amherst was not operating for an extended period of time, according to Reams.

In nearby Mont Vernon, about half the town was without electricity Tuesday morning. Three major road closures were causing some concerns, including a portion of Route 13, Kendall Hill Road and Harwood Road, said Police Chief Kyle Aspinwall.

Although a fallen tree had been removed along Route 13 in Mont Vernon, he said live wires were still in the roadway Tuesday morning. Brook Road is a low-lying area in town, but Aspinwall said he monitored that area and there was no immediate flooding concerns.

The Mont Vernon Fire Department was having problems with its primary radio antenna on Tuesday, according to Aspinwall. "The fire department can't transmit off their base radio," he said, explaining the FairPoint Communications relay station in Mont Vernon was without power, and a generator had not been installed as of Tuesday morning.

Although it is not ideal to use the two other radio antennas from Wilton and Milford, Aspinwall said communication was still possible. FairPoint operates the Mont Vernon Fire Department communications system, which also houses the town's emergency operation center. As of Tuesday morning, FairPoint was still down in the area, said police.
