Page 9 Natural Disasters In Canada over the last century, 80% of all natural disasters were Weather or Water related!!! (Pine Lake July 2000, photo courtesy Dennis Dudley EC)
Page 10 Emergencies – Direct Result of Weather Thunderstorms (large hail, damaging winds, intense lightning, flash flooding) Damaging winds (non Thunderstorm) Heavy Rains (flooding) Tornadoes (Saskatchewan ~ 12/year) Heavy Snow Blizzards Extreme Wind chills Freezing Rain

Weather Information that Environment Canada provides and where you can find it 21
Environment Canada’s Weather Service number 1 mandate is to provide Canadians with as much lead time as possible in advance of severe events throughout the year 22 Environment Canada Watch/Warning Program
Weather Warnings, Weather Watches and Special Weather Statements 23
Special Weather Statement Significantly unusual and noteworthy weather that does not necessarily meet weather warning criteria –Early or Late seasonal Snowfall (less than 10 cm) –Extensive fog, smoke or airborne dust –Patchy freezing drizzle Lead time 12 hours to 2 days 24
Weather Watch WATCH - Yellow Alert –Nothing may be happening, but the potential exists for severe thunderstorms to develop within the next few hours (watch generally issued with 2-6 hrs lead time) –Stay tuned for updated forecasts/warnings Summer (Thunderstorm and Tornadoes) - target lead time Tornado watch: 1 to 2 hours - target lead time for Thunderstorm watch: 6 hours Winter (Winter Storms) - target lead time 12 to 48 hours
Weather Warning WARNING – Red Alert –Tornado and Severe Thunderstorm Warnings Severe weather is occurring or immanent, Take immediate action! –Other Weather Warnings Severe weather is occurring or is expected to occur within the next 12 hours Summer (Tornadoes and Severe Thunderstorms) - target lead time for Tornado Warnings: 30 minutes - target lead time for Severe Thunderstorm Warnings: 30 minutes Other Weather Warnings (Blizzard, Snowfall, Rainfall, Wind, etc) - target lead time 12 hours 26
Weather Watch – Be aware of the potential dangers !
Weather Warning – Take Action!
Lightning… Environment Canada Does not issue Watches and Warnings if lightning is the only threat.

Emergency Exercises Assist in hazard identification and risk assessment Assist in exercise design Provision of mock weather bulletins Presentation on severe weather as prelude to exercise
Page 45 EC Storm Prediction Centres STORM ( ) To be used by Emergency Management Personnel (municipal, provincial or federal) for major emergencies or catastrophic events when; –Current weather forecast lacks detail necessary to combat situation or Significant discrepancy between EC weather forecast and current conditions

Page 58 Future EC Weather Services “Early Notification Project” Providing some type of information service to highlight significant weather for a 3 day period Focus on “High Impact Weather” Base weather information on known weather sensitivities
Page 59 EMO Weather Outlook (Example) Significant Weather Discussion for Ontario Provincial Emergency Operations Centre provided by Environment Canada’s Ontario Storm Prediction Centre issued at 5:00 AM EST Friday 20 January Discussion valid for today, tonight and Saturday with an outlook for Sunday. Today… Cold Arctic air will generate flurries and localized snow squalls to the east of Lake Superior, affecting Hwy 17. A snow squall watch will likely be upgraded to a warning as the squalls intensify later this morning. Snowfall amounts up to 15 centimetres are possible. Otherwise no significant weather is expected. Tonight... Flurries and squalls east of Lake Superior will gradually weaken and shift south. An area of snow from a passing disturbance south of the Great Lakes will give upwards of 5 cm across southwestern Ontario (grazing the GTA). There is high confidence in this event. Saturday… No significant weather is expected. Outlook for Sunday... A more significant disturbance will head towards the upper Great Lakes with 10 to 15 centimetres of snow possible around Lake Superior and northeast toward Hearst and Timmins.
