21 Weather Information that Environment Canada provides and where you can find it
22 Environment Canada Watch/Warning Program 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
23 Weather Warnings, Weather Watches and Special Weather Statements
24 Special Weather Statement Significantly unusual and noteworthy weather that does not necessarily meet weather warning criteriaEarly or Late seasonal Snowfall (less than 10 cm)Extensive fog, smoke or airborne dustPatchy freezing drizzleLead time 12 hours to 2 days
25 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/warningsSummer (Thunderstorm and Tornadoes)- target lead time Tornado watch: 1 to 2 hours- target lead time for Thunderstorm watch: 6 hoursWinter (Winter Storms)- target lead time 12 to 48 hoursSevere Thunderstorm Watches are issued when conditions are favourable for the development of severe thunderstorms with large hail, heavy rain, or damaging wind, as identified by the severe weather analysis.Objective Criteria:RAIN (MB, SK, AB) - 50 mm or more of rain in 1 hour or less, or 75 mm in 3 hours or less.RAIN (NT, NU) - 25 mm or more of rain in 1 hour or less.HAIL (MB, SK, AB) - 20 mm or larger in diameterHAIL (NT, NU) - 12 mm or larger in diameterWIND - gust of 90 km/h or greater (including Crowsnest, Cardston and Lethbridge regions)TORNADO - tornado or waterspout spotted (only includes tornadic waterspouts)Subjective criteria:RAIN - flooding which causes damage or serious inconvenience, but does not meet the objective criteriaHAIL - significant damage, but less than 20 mm in diameter (such as when accompanied by a strong wind)WIND - wind less than 90 km/h when there is significant damageTarget lead time for a Severe Thunderstorm Watch is 6 hours.
26 Weather Warning WARNING – Red Alert Tornado and Severe Thunderstorm WarningsSevere weather is occurring or immanent, Take immediate action!Other Weather WarningsSevere weather is occurring or is expected to occur within the next 12 hoursSummer (Tornadoes and Severe Thunderstorms)- target lead time for Tornado Warnings: 30 minutes- target lead time for Severe Thunderstorm Warnings: 30 minutesOther Weather Warnings (Blizzard, Snowfall, Rainfall, Wind, etc)- target lead time 12 hours

43 Environment Canada EMO Training Sessions Weather Services for EMO’sWeather Safety and Weather Preparedness (general weather)Storm Recognition (summer focus)
44 Emergency ExercisesAssist in hazard identification and risk assessmentAssist in exercise designProvision of mock weather bulletinsPresentation on severe weather as prelude to exercise
45 EC Storm Prediction Centres 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

56 MASAS (Multi-Agency Situational Awareness System) Goal: Enable sharing of location based situational awareness non-sensitive informationand alerts between Emergency Management and Response Agencies

58 Future EC Weather Services “Early Notification Project” Providing some type of information service to highlight significant weather for a 3 day periodFocus on “High Impact Weather”Base weather information on known weather sensitivities
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 2012. 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.
