More than 21,000 Augusta-area households are without power tonight, Central Maine Power Co. is reporting.

The morning’s wet, heavy snow, topped off with the afternoon’s freezing rain, has weighed down tree limbs and power wires statewide and, locally, from Sidney to Bowdoin.

Central Maine Power crews and local fire departments have responded to a number of transformer fires and smaller fires sparked by tree limbs crashing down onto power lines.

Multiple roads are partially blocked by downed trees. Route 32 was reported closed in Windsor.

The outages — which are affecting more than 75,000 Central Maine Power customers throughout the company’s service area — are the latest effects of a storm that led to flooding on roads throughout the area today.

The number of power outages rose quickly — to 22,216 in the Augusta-area and 79,418 — until about 8:20 tonight. The numbers have fallen slightly since then, according to CMP officials.

On the ground, public works crews in Augusta and Hallowell tried dig out storm basins today to allow the puddled water to drain before freezing over.

Augusta Public Works director John Charest said crews had some success in digging out storm basins.

“The problem was just that it was so much slush that you open it up and five minutes later it was plugged again,” he said.

The challenging part of storm, Charest said, was the freezing rain that followed seven inches of snow that fell on Augusta this morning.

“The snow wasn’t bad,” he said. “The rain came and screwed everything up.”

Charest warned of slippery roads in the moming as temperatures dip to about 25 degrees and puddles on the roadways freeze over.
