Just received this report from a friend in the USA regarding extremely bad cold wave.
He lives in New England and for the last 2 days, they've had non-stop snow & temperature going down to - 20 C and gale force winds of up to 60mph.
They are totally isolated and his mother-in-law hasn't done anything else other than looking through the kitchen window.
He was saying that if it carries on like that he will have no alternative but to let her in!
