If you are like most Canadians you have probably had to clean up after these storms and you know the damage they cause. Some problems cannot be pre vented. High winds will topple trees and heavy rains will cause rivers to flood. But some damage can be avoided or at least reduced, if you take a few simple precau tions such as knowing the type of storms common to your area and what time of year they are likely to strike. The purpose of this booklet is to help you prepare for severe weather by listing a few steps which you can take to protect your family, yourself, and your property when a severe storm hits your area. strong foundation. If no shelter is available, then lie down in a ditch away from the auto mobile or mobile home. · If you are driving and spot a tornado in the distance, try to get to a nearby shelter. If the tornado is close by, get out of your car and take cover in a low-lying area or even under an underpass on a freeway. Crawl right up the bank to just under the road of the over pass. If a tornado seems to be standing still then it is either travelling away from you or heading right for you. · In all cases, get as close to the ground as possible, protect your head and watch out for flying debris. Small objects such as sticks and straws can become lethal weapons when driven by a tornado's winds. storms. Floods may also result if a heavy rain coincides with the spring thaw. · If you know there is flooding or the possibili ty of flooding in your area, keep your radio on to find out what areas are flooded, what areas are likely to be flooded as well as what roads are safe, where to go and what to do if the local emergency team asks you to leave your home. · Generally speaking, it is a good idea to avoid driving through flooded roads and underpasses. The water may be a great deal deeper than it looks and you could get stuck. You may also want to avoid crossing bridges if the water is high and flowing quickly. Hail Hail forms when updrafts in thunderclouds carry raindrops upwards into extremely cold areas of the atmosphere. The raindrops freeze and are bounced around in the power ful winds within thunderclouds while new lay ers of ice are added. Eventually, the hail stones grow too heavy to be supported by the updrafts and fall to the ground. Some hail stones are the size of peas while others can be as big as grapefruits. Take cover when hail begins to fall. Do not go out to cover plants, cars or garden furni ture or to rescue animals. Hail comes down at great speed, especially when accompanied by high winds. Although no-one in Canada has ever been killed by hail, people have been seriously injured by it. LISTEN FOR THE WARNINGS Environment Canada monitors the weather 24-hours a day, seven days a week. If a severe storm is on the horizon, the weather service issues watches, advisories and warn ings through national, regional and local radio and television stations, and Environment Canada's Weather radio. Weather Watch: conditions are favourable for a severe storm, even though one has not yet developed. Weather Advisory: the actual or expected weather conditions may cause concern or general inconven ience, but do not pose a serious enough threat to warrant a weather warning. Weather Warning: severe weather is happening or hazardous weather is highly probable. If a weather warning is issued for a tornado, it means that one or more tornadoes have been observed or are forecast for the speci fied area. Other warnings include those for a severe thunderstorm, blizzard, high winds, heavy snow, snow squall, heavy rain and heavy freezing rain. SEVERE STORMS Tornadoes Tornadoes form suddenly, are often preceded by warm humid weather and always pro duced by thunderstorms - although not every thunderstorm produces a tornado. There are warning signs, including: · severe thunderstorms with frequent thunder and lightning · an extremely dark sky sometimes highlight ed by green or yellow clouds · a rumbling sound, such as a freight train might make or a whistling sound such as a jet aircraft might make · a funnel cloud at the rear base of a thunder cloud often behind a curtain of heavy rain or hail. Tornadoes are violent windstorms charac terized by a twisting funnel-shaped cloud SEVERE THUNDERSTORMS - LIGHT NING, HEAVY RAIN and HAIL A 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. WINTER STORMS: FREEZING RAIN, HEAVY SNOW, BLOWING SNOW and BLIZZARDS Blizzards come in on a wave of cold Arctic air, bringing snow, bitter cold, high winds and poor visibility. In Canada, blizzards are most common in the southern Prairies, the Maritimes and the eastern Arctic. On average, the storms and cold of 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 fre quent, 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. · When a blizzard is forecast, leave your radio on. If you are on a farm with livestock, bring the animals into the barn. Make sure they have plenty of water and food. You may also want to string a lifeline between your house and any outbuildings which you may have to go to during the storm. · When a blizzard hits, stay indoors. If you must go to the outbuildings, dress for the v\*eather. Outer clothing should be tightly woven and water-repellent. The jacket should have a hood. Wear mittens - they are warmer than gloves - and a hat, as most body heat is lost through the head. · In wide open areas, visibility can be virtual ly zero. You may easily lose your way. If a blizzard strikes, do not try to walk to anoth er building unless there is a rope to guide you or something you can follow. 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 two small emergency kits - one to put in the trunk of your car and the other in the cab of the car. The trunk kit should include: · shovel, sand, or salt or kitty litter · tow chain and booster cables · fire extinguisher, warning light or flares · extra clothing, including mittens, hats and boots. The kit in the cab of the car should include: · flashlight · blanket · first aid kit · matches, candles (in a deep can to warm hands or heat a drink) and emergency food pack. If you do not already have a cellular tele phone - and if they work in your area - you may want to consider having one in your car for 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 - away from the wind. You can run the car engine about 10 minutes every half hour if the exhaust system is work ing 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 shovelling and bitter cold can kill. Keep watch for traffic or searchers. BE PREPARED Storms such as tornadoes Qften strike too quickly to allow you to choose a shelter or pack an emergency kit. You may want to have a plan that outlines where you will go and how you will keep in touch with members of your family if a severe storm hits. Municipal, provincial and territorial emer gency measures organizations can provide valuable advice to help you prepare for emer gencies. Choose your shelter area A basement, storm cellar or a closet beneath the stairs are good places to take shelter in the event of a severe storm. If none of these is available, sit underneath a sturdy piece of furniture on the ground floor in the centre of the building away from the outside walls and windows. Be sure you discuss the shelter area with your family. Pack an emergency kit This should include food, clothing, blan kets, medication, water purification tablets and first-aid and tool kits as well as flashlights and a battery-powered radio - with extra bat teries for both. Reduce the hazards Trim dead or rotting branches and cut down dead trees to reduce the danger of these falling on your house. You may also want to consider checking the drainage around the house to reduce the possibility of your basement flooding after a heavy rain. Choose a place to meet When a severe storm strikes, members of your household may be at work, school or a friend's place. To avoid unnecessary worry, plan a meeting place or some system of com municating with one another to check that everyone is safe. THINGS TO DO AFTER THE STORM Listen to your radio for information and fol low instructions. Give first aid to people who are injured or trapped. Get help if necessary. Unless you are asked to help or are quali fied to give assistance, please stay away from damaged areas. Do not go near loose or dangling power lines. Report them and any broken sewer and water mains to the authorities. Report fires to the fire department. Be alert to prevent fires, as broken water mains may cause a reduction in water pressure. Lightning and downed power lines can cause fires. Know how to fight small fires. Water supplies may be contaminated so purify your water by boiling it for 10 minutes, or by adding water purification tablets, or by adding one drop of unscented chlorine bleach to one litre of water (or three drops for cloudy water). If you use chlorine bleach to purify the water, stir the bleach in and wait 30 minutes before drinking. The water should have a slight chlorine smell. Please leave the telephone lines free for official use. Do not use the telephone, except in real emergencies. Drive cautiously and only if necessary. Debris, broken power lines and washed out or icy roads and bridges will make driving dangerous after a severe storm. Please give way to emergency vehicles at all times. Finally, if the power has been off for sever al hours, check the food in the refrigerator and freezer to make sure it has not spoiled. which forms at the base of cloud banks and points towards the ground. Tornadoes usual ly move over the ground at anywhere from 20 to 90 km/h and often travel from the south west to the northeast. They are erratic and can change course suddenly. It is not a good idea to chase tornadoes. Generally speaking, May to September are prime tornado months. Tornadoes usually hit in the afternoon and early evening but they have been known to strike at night too. Canada has several high risk areas includ ing Alberta, southern Ontario, southwestern Quebec and a band of land which stretches from southern Saskatchewan and Manitoba through to Thunder Bay, Ontario. There are also tornado zones in the interior of British Columbia and in western New Brunswick. Things to do in a tornado · If you live in one of Canada's high-risk areas or zones, you should listen to your radio during severe thunderstorms. As a rule, when Environment Canada issues a torna do warning, radio stations broadcast it immediately. If you hear that a tornado warning has been issued for your area, take cover immediately. If you are at home, go to the basement or take shelter in a small inte rior ground floor room such as a bathroom, closet or hallway. Failing that, protect your self by taking shelter under a heavy table or desk. In all cases, stay away from windows and outside walls and doors. · If you are at the office or in an apartment building, take shelter in an inner hallway or room, ideally in the basement or the ground floor. Do not use the elevator and stay away from windows. Avoid buildings such as gym nasiums, churches and auditoriums with freespan roofs. These roofs do not have supports in the middle and may collapse if a tornado hits them. If you are in one of these buildings take cover under a sturdy struc ture. · Do not get caught in a car or mobile home. More than 50 per cent of all deaths from tor nadoes happen in mobile homes. Take shel ter elsewhere - such as a building with a Lightning The air is charged with electricity during a thunderstorm. The most striking sign of this is lightning. Bolts of lightning hit the ground at about 40,000 kilometres per second - so fast that the lightning appears to be a single main bolt with a few forks when actually the oppo site is true. The main bolt is a whole series of lightning strikes all taking the same path but at such a pace that the eye cannot distinguish between them. To estimate how far away the lightning is, count the seconds between the flash of light ning 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 · If indoors, stay there but away from win dows, doors, · If indoors, stay there but away from win dows, doors, fireplaces, radiators, stoves, sinks, bathtubs, appliances, metal pipes, telephones and other materials which con duct electricity. (You can use a cellular tele phone.) · Unplug radios and televisions. · Do not go out to rescue the laundry on the clothesline as it conducts electricity. Outside ·Take shelter in a building or depressed area such as a ditch or a culvert but never under a tree. ·Do not ride bicycles, motorcycles or golf carts or use metal shovels or golf clubs as they conduct electricity. · If swimming or in a boat, get back to shore immediately. ·If caught in the open, do not lie flat but crouch in the leap frog position and lower your head. · If you are in a car, stay there but pull away from trees which might fall on you. Heavy rain A heavy rain fall can result in flooding. This is particularly true when the ground is still frozen or already saturated from previous
