CAMDEN — The southeast half of the state remains under an ice storm warning Sunday morning, with Mainers waking up to ice covered decks, porches, sidewalks and driveways.

Road crews had been out earlier, sanding and “salting” the roads, which are mostly clear, though slick spots may linger and return throughout the day into Monday.

The National Weather Service’s ice storm warning remains in effect through Monday, Dec. 23, at noon. Ice accumulations up to 1/2-inch are predicted, with freezing rain mixing with sleet and snow Sunday morning. Freezing rain will continue on and off through Sunday night into Monday morning.

Tree limbs already have approximately 1/4-inch of ice coating them, and the sound is like a crackling sound when the breeze causes the branches to move, hitting each other and cracking the ice coating.

So far, this ice storm is nothing like the ice storm of 1998, which causes widespread power outages and down limbs and whole trees.

Central Maine Power is not reporting any power outages in Knox County as of 10 a.m. Sunday, and only a dozen customers in Waldo County are without power this morning. CMP is reporting its greatest outage area is in Hancock County, where 1,532 of its 5,986 customers there are currently without power. The second largest affected county is York, where 332 of CMP’s total 115,068 customers there are without power Sunday morning.

Local and state Emergency Management Agency and utility officials urge the public to treat all downed lines as live, and to report such incidents by calling 911. Power outages can be reported by calling 1-800-696-1000. For those without power who still have access to the Internet, outage reports for CMP customers can be made online here.

The most dangerous hazard during power outages is improper use of generators, according to the National Weather Service.

Portable generators must be run outside, at least 15-feet from windows or doors, to avoid life-threatening carbon monoxide poisoning. CO gas can be deadly if it builds up inside a home, garage or basement. Make sure to have CO detector with a battery back-up where people sleep, and check detector batteries often.

Those who lose power are also reminded not to use grills or camp stoves indoors due to the potential for CO gas buildup.

Signs of CO poisoning are headache, nausea, vomiting and dizziness. Breathing CO gas can cause loss of consciousness and death. If you or a family member suspect CO poisoning, get out of the house and call 911 immediately.
