Special Statement

Expires 11:00 PM EST on February 11, 2016
Statement as of 2:21 PM EST on February 11, 2016

... Potentially life threatening wind chills with extreme cold
this weekend...

* temperatures this weekend will fall below zero Sat night into
early Sunday morning across most of the region including the
cities of Boston... Providence... Hartford and Worcester.

* The core of cold air arrives Saturday afternoon and then settles
over the region Saturday night and Sunday. Bitterly cold winds
will ease Sunday night into Monday but actual air temperatures
will remain very cold.

* Northwest winds of 15 to 25 mph with gusts up to 40 mph will
result in wind chill values between 15 and 25 degrees below
zero... with the coldest values across the higher terrain where
30 degrees below zero wind chills are possible! These values
will result in frostbite to occur in 10 minutes or less on
exposed skin. Residents are highly encouraged to take proper
precautions with limiting exposed skin.

* If you have not done so already... be sure to cover exposed pipes
to reduce the threat of frozen pipes or pipe bursts.

* Ensure your furnaces are in working order. Follow manufactures
instructions or utilize a qualified technician to ensure proper
and safe operation of your furnace.

* Never venture outdoors without wearing gloves... a hat and
several layers of clothing.

* Run water at a trickle and keep Cabinet doors open to prevent
pipes from freezing.

* Never use a stove or oven to heat your home or use an open flame
to melt frozen pipes. Many house fires result from these
practices.

* Never use a generator near or inside your home. Carbon monoxide
poisoning is deadly. Check or install Carbon monoxide
detectors.

* Check tire pressure and your car battery. Be sure your car has
a winter safety kit that includes a blanket... warm clothes and
gloves in case your car breaks down or becomes stranded.

* Take extra steps to keep your pets warm and know their limits to
cold.
