One of the worst effects of snow storms is the affectation to the fast-moving transport and supply network of our modern cities, in many cases trapping people in their cars, trains or airports without the proper resources and collapsing the public services that should rescue them, or leaving without critical food or medical supply to remote communities.

These serious effects can be minimized by proper planning thanks to forecast applied directly to prevent infrastructure use under extreme events, but also minimizing generalized warnings that could affect the operations where actual snow accumulation is unlikely to happen.
