"The extreme cold and heavy snowfall that accompany winter storms can be debilitating and dangerous. Winter storms can affect everyone, even those who usually experience mild winters. Heavy snowfall can be blinding for drivers and dangerous for those it traps indoors. Winter storms may also include high winds, sleet, freezing rain, frozen roads, power outages and dangerously cold temperatures."
