1 Edmonton Tornado- Picture 1 The Edmonton tornado of 1987, an event also known as Black Friday to Edmontonians, was a powerful and devastating tornado that ripped through the eastern part of Edmonton, Alberta, Canada and parts of neighbouring Strathcona County on the afternoon of Friday, July 31, 1987.tornadoEdmontonAlbertaCanadaStrathcona County The tornado remained on the ground for an hour, cutting a swath of destruction 40 kilometres (25 mi) long and up to a kilometre (0.6 miles, or 3000 feet) wide in places, and peaking at F4 [2] on the Fujita scale. The tornado killed 27 people, injured more than 300 people, destroyed more than 300 homes, and caused more than $332.27 million CAD ($581 million in 2013 dollars [1] ) in property damage at four major disaster sites. The loss of life, injuries and destruction of property made it the worst natural disaster in Alberta's recent history and one of the worst in Canada's history. [2]Fujita scale [1] Weather forecasts issued during the morning and early afternoon of July 31, 1987 for Edmonton revealed a recognition by Environment Canada of a high potential for unusually severe thunderstorms that afternoon. Environment Canada responded swiftly upon receipt of the first report of a tornado touchdown from a resident of Leduc County which is immediately adjacent to Edmonton's southern boundary. At least four other tornadoes were reported that day in central Alberta between Millet and Vegreville. [3]Environment Canada thunderstormsLeduc County [3]

2 About the Ice Storm of 1998: Picture 2 For six days in January 1998, freezing rain coated Ontario, Quebec and New Brunswick with 7-11 cm (3-4 in) of ice. Trees and hydro wires fell and utility poles and transmission towers came down causing massive power outages, some for as long as a month. It was the most expensive natural disaster in Canada. According to Environment Canada, the ice storm of 1998 directly affected more people than any other previous weather event in Canadian history.

5 Disaster!- Picture 3 On June 29, 1864 a Grand Trunk train carrying between 354 and 475 passengers, many of them German and Polish immigrants, were travelling from Quebec City to Montreal. [1][3] Quebec City Montreal [1][3] At around 1:20 a.m. local time the train was approaching a swing bridge known as the Beloeil Bridge on the Richelieu River. [4] The swing bridge had been opened to allow the passage of five barges and a steamer ship. A red light a mile ahead of the bridge signalled to the train that the crossing was open and it needed to slow down. [3] However the light was not acknowledged by the conductor, Thomas Finn, or the engineer, William Burnie, and the train continued towards the bridge. [4][5] [4] [3] [4][5] At 1:20 a.m. the train came onto the bridge and fell through an open gap. The engine and eleven coaches fell through the gap one after another on top of each other crushing a passing barge. The train sank into an area of the river with a depth of 10 feet. [1] 99 people aboard the train were killed and 100 more were injured. [1] Among the dead was Thomas Finn and the fireman aboard the train. The engineer was slightly hurt in the accident but was able to escape the wreck. The disaster was blamed on the conductor and engineer for failing to follow the standing order to stop before crossing the bridge. The engineer, who had only recently been hired, claimed that he was not familiar with the route and that he did not see the signa [1]

8 Picture 5 Hurricane Juan was a significant hurricane that struck the southern part of Atlantic Canada in late September 2003. It was the tenth named storm and the sixth hurricane of the 2003 Atlantic hurricane season. hurricane Atlantic Canada 2003 Atlantic hurricane season Juan formed southeast of Bermuda on September 24, 2003 out of a tropical wave that tracked into the subtropical Atlantic Ocean. It strengthened gradually in the warm waters of the Gulf Stream, reaching Category 2 strength on the Saffir-Simpson hurricane scale on September 27 while continuing to track northward. It peaked at 105 mph (165 km/h) as it rapidly approached the coast of Nova Scotia, losing little intensity over the cooler waters. Juan made landfall between Shad Bay and Prospect in the Halifax Regional Municipality early on September 29 as either a strong Category 1, or weak Category 2 hurricane with peak sustained winds of 94 mph (152 km/h), as measured at the McNab's Island Lightstation [1]. Juan retained hurricane strength as it crossed Nova Scotia from south to north before weakening to a tropical storm as it crossed Prince Edward Island. It was absorbed by another extratropical low later on September 29 near Anticosti Island in the northern Gulf of Saint Lawrence.

Most of the damage was as a result of the high winds that whipped across the region. Juan resulted in eight fatalities and over $300 million (2003 CAD, $200 million 2003 USD) in damage. It was described as the worst storm to hit Halifax since 1893. [2][3] CADUSD 1893 [2][3]
