Days of severe weather including heavy rain, thunderstorms, hail, tornadoes and flooding led officials in western Alberta to declare a state of emergency.

However, Yellowhead County (west of Edmonton) dropped the declaration on Wednesday when floodwaters receded.

Many roads had to be closed or were made impassable after flooding and drivers were being asked to obey any barriers in place.

Residents were being warned about possible contamination of their drinking water.

Yellowhead County officials say at least 25 homes were directly impacted by floodwaters.

Tornado hits National Capital Region

 

A tornado developed about 10 kilometres southeast of Gatineau Airport, Quebec early Sunday evening.

The tornado moved east along the Ottawa River before coming ashore on the Ontario side.

In the suburban Ottawa neighbourhood of Orléans, strong winds brought down trees and removed shingles on many homes with one person reportedly injured.

A thunderstorm also produced 2 centimetre hail in the area.

Environment Canada says the tornado was a low end EF-1 suggesting peak winds of 135 km/h and had a path length of at least 25 kilometres.

Tornadoes tear through Ottawa

Environment Canada has confirmed two powerful tornadoes ripped through west end Ottawa before touching down again in Gatineau across the Ottawa River.

Officials say dozens were hurt and at least two residents are in hospital with critical injuries.

Tens of thousands were left without power after at least 80 utility poles either snapped or were damaged.

Meteorologists say severe thunderstorms spawned one twister classified as an EF-3 with winds up to 265 km/h while another tornado was an EF-2 with winds up to 220 km/h.

Tornadoes are not uncommon in Southern Ontario but storms of this strength are rare.

Gordon hits U.S. Gulf Coast

Tropical Storm Gordon has claimed at least one life after striking the American Gulf Coast late Tuesday near the Alabama-Mississippi border.

Authorities say strong winds caused a tree to fall on a mobile home in Pensacola, Florida where a child was found deceased.

The U.S. National Hurricane Centre says Gordon weakened as it moved inland and was not powerful enough to reach hurricane status.

Tornado warnings were issued after radar showed possible twisters stemming from the storm.

Forecasters say as much as 200 cm of rain (almost 80 inches) could fall and the system could have an impact on Eastern Canada by early next week.

Rare tornado warning for Northwest NB!

Severe thunderstorms prompted Environment Canada to issue a rare tornado warning for northwestern New Brunswick late Tuesday afternoon.

The warning was in place for about 30 minutes and covered Victoria County including Grand Falls and Plaster Rock.

Meteorologists said a storm cell showed signs of rotation on radar which was capable of producing a tornado.

However, there were no reports of twisters actually touching the ground.

Two tornadoes have been confirmed in Haldimand, Norfolk and Oxford counties as severe thunderstorms rolled through Southwestern Ontario on 13 June.

Environment Canada says a tornado categorized as an EF-2 (Enhanced Fujita Scale 2) with maximum winds of 180 km/h ripped through the communities of Jarvis and Waterford uprooting trees, ripping shingles off buildings and destroying several barns.

Damage was reported intermittently along a path roughly 32 km long.

A second, less powerful twister categorized as an EF-0 struck near the town of Norwich around the same time and caused minimal damage.

Harvey hammers Houston

Harvey may have been downgraded to a tropical storm as it moved inland over Texas but the U.S. National Weather Service stated “this event is unprecedented and all impacts are unknown and beyond anything experienced.”

Forecasters say the Houston metropolitan area could receive more than 1000 mm of rain from the storm over the next few days which has claimed at least five lives. 

By early today, more than 600 mm had fallen in America’s fourth largest city overwhelming lakes and rivers forcing thousands of residents scrambling into boats or onto rooftops to safety.

Tornado warnings have been lifted but a flash flood warning remains in place for much of southeastern Texas.

A sudden and powerful storm which meteorologists call a microburst created a path of damage in Montreal which included the Notre-Dame-de-Grace borough.

Strong, gusty linear winds up to 120 km/h brought down trees and power lines leaving thousands without electricity on Tuesday.

Environment Canada has confirmed a tornado struck Lachute, northwest of Montreal, where winds reached up to 180 km/h.

An unstable air mass moved from west to east in New Brunswick producing severe thunderstorms bringing torrential rain, large hail and strong winds.

Environment Canada believes a severe thunderstorm formed near Doaktown and possibly spawned a tornado that moved into the Blackville area last night.

Golf ball size hail and damaging winds with gusts up to 100 km/h were recorded in the Plaster Rock area.

Southeast New Brunswick has seen an above average 18 days with thunderstorm activity this June and a severe thunderstorm watch was issued in the region this afternoon.
