SEVERE STORMSA thunderstorm develops in an unstable atmosphere when warm moist air near the earth's surface rises quickly and cools. The moisture condenses to form rain droplets and dark thunder clouds called cumulonimbus clouds. These storms are often accompanied by hail, lightning, high winds, heavy rain and tornadoes. Thunderstorms are usually over in an hour, although a series of thunderstorms can last for several hours.
Lightning To estimate how far away the lightning is, count the seconds between the flash of lightning and the thunderclap. Each second is about 300 metres. If you count fewer than five seconds, take shelter immediately. Lightning is near and you do not want to be the tallest object in the area. At the office or house

Blizzards In Canada, blizzards are most common in the southern prairies, the maritimes and the eastern arctic. On average, the storms and cold winter kill more than 100 people every year. That is more than the total number of people killed by hurricanes, tornadoes, floods, lightning and extreme heat.
At Home If you live in a rural community located in one of the areas where blizzards are frequent, you may want to consider stocking up on heating fuel, ready-to-eat food as well as battery-powered flashlights and radios - and extra batteries.
In your car As a rule, it is a good idea to keep your gas tank almost full during the winter and to have extra windshield washer fluid and anti-freeze on hand. You may want to put together an emergency kit. If you do not already have a cellular phone - and if they work in your area - you may want to consider having one in your car in case of emergencies. If you must travel during a snow storm, do so during the day and let someone know your route and arrival time. If your car gets stuck in a blizzard, remain calm and stay in your car. Keep fresh air in your car by opening the window slightly on the sheltered side. You can run the car engine about 10 minutes every half hour if the exhaust system is working well. Beware of exhaust fumes and check the exhaust pipe periodically to make sure it is not blocked with snow. (Remember, you can't smell potentially fatal carbon monoxide fumes.) Finally, to keep your hands and feet warm, exercise them periodically. In general, it is a good idea to keep moving to avoid falling asleep. If you do try to shovel the snow from around your car avoid over-exerting yourself as shoveling and bitter cold can kill. Keep watch for traffic and searchers.
