What Have We Done to Prevent Deaths and Injuries in Blizzards?

We now have Doppler radar that tells us what the storm will bring for us. We also have T.V., radios, and phones to tell us how bad the storm will be and if we can or can not go out in to the storm. We also have built stronger houses to withstand the winds from the blizzards. We have also put insulation in our houses to keep the warm air in and the cold air out.
