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.

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.

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.

Irma swamps Florida

Irma was downgraded from a hurricane to a tropical storm today after slamming Florida with destructive wind, heavy rain, flash flooding, high storm surges and even tornadoes.

Irma, one of the most powerful hurricanes ever recorded in the Atlantic Ocean, made landfall over the Florida Keys on Sunday before coming ashore near Naples and then heading up the state’s west coast.

Miami was not in the storm’s direct path but was still battered by strong winds which swayed high rise buildings, brought down three construction cranes and downtown streets were swamped.

In northeast Florida, Jacksonville had historic flooding after the swollen St. Johns River spilled its banks and officials said dangerous conditions were expected for several days.

Prior to arriving in the United States, Irma claimed 10 lives in Cuba according to state media after battering Havana and tourist resorts such as Varadero and Cayo Coco where the international airport was destroyed.
