More than 70 million people across the US were put under winter weather alerts this past week, from Oregon to Maine. Temperatures fell to -45C in some areas, and the National Weather Service (NWS) issued a wind chill warning across parts of Texas through last weekend, with warnings of hypothermia and frostbite from wind chills of -32C.
Additionally, nearly 10in (25cm) of snow fell across parts of Iowa, and other states across the midwest received six to 10in of snow last weekend.
