Northerly winds are driving down already bone-chilling temperatures as yet another Arctic front sweeps the north country.
The low recorded at Watertown International Airport was minus 19 degrees Monday night. In Massena, it reached minus 25 degrees, the National Weather Service reported.
Single-digit temperatures will continue until Thursday, with wind chills dropping as low as minus 40 degrees Tuesday night, according to the National Weather Service.
The services wind-chill advisory was lifted at 11 a.m. Tuesday. A wind-chill warning that began at 6 p.m. Tuesday remains in effect until 1 p.m. today.
It was sunny but cold Tuesday with a high of minus 3 degrees and wind chills as low as minus 25 degrees.
Today will remain bitter cold with below-zero highs and wind chills dipping down to negative 40 degrees.
The Arctic chill will linger until Thursday, with an expected high near 1 degree and lows around minus 11 degrees.
Temperatures are expected to rise back up to 18 degrees Friday afternoon, but forecasters with the National Weather Service are expecting snow that day and over the weekend.
Because of the extreme cold, the American Red Cross has urged area residents to be prepared for the freeze by following these steps:
■ Wear layers of lightweight clothing. Gloves and a hat will help prevent losing body heat.
■ Be extremely careful if you have to shovel snow. Take frequent breaks and stay hydrated.
■ Seek medical attention immediately if you have symptoms of hypothermia, including confusion, dizziness, exhaustion and severe shivering.
■ Watch for symptoms of frostbite, including numbness, flushed gray, white, blue or yellow skin discoloration, numbness, or waxy feeling skin.
■ Bring your pets indoors. If they cant come inside, make sure that they have enough shelter to keep them warm and that they can get to unfrozen water.
■ Avoid frozen pipes by running water, even at a trickle, to help prevent them from freezing. Open the kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. If children are nearby, be sure to move any harmful cleaners and chemicals out of reach. Keep garage doors closed if there are water lines in the garage.
■ Keep the thermostat at the same temperature day and night. Your heating bill may be a little higher, but you could avoid a more costly repair job if your pipes freeze and burst.
