It is hard to hide from a winter storm. Often they are so large they can stay over an area for days, like the winter storm that struck Halifax in February 2004, or the blizzard that sat over southern Saskatchewan for 10 days in 1947.     Research Like all storms, scientists cannot stop a storm from forming, but with increased research they may be able to detect when a severe storm is going to develop, giving citizens more time to prepare. With advances in meteorological instruments and increased knowledge as to what makes the storms develop, we have a better chance at reducing our losses in the event of a winter storm. The most people can do when a storm is approaching, however, is to prepare for the worst.     Personal Preparedness   Have the following supplies on hand in advance: Battery operated radio Spare batteries Flashlights Non-perishable food Drinkable water Adequate supply of medication Plumbing antifreeze Alternative heat source, such as wood stove, fireplace or CSA-approved space heater. Fire extinguisher, smoke detector and carbon monoxide detector.     In the event of a power outage, take the following precautions: Avoid opening doors unnecessarily. Turn off all electrical appliances. Use your alternate heat source to minimize heat loss. Ensure that you maintain adequate ventilation. Most natural gas fireplaces will operate without a power source. If the power outage is prolonged and pipes are in danger of freezing, turn off the main water valve and drain the line by running taps. Put plumbing antifreeze in toilet bowls, sinks and bathtub drains. Turn off and drain your hot water heater by connecting a hose to the drainage tap of the tank.
