  Province declares high water advisory as rivers and lakes continue to rise Manitoba Infrastructure’s Hydrologic Forecast Centre says that a high water advisory is in place for southern Manitoba and the Whiteshell lakes area. READ MORE: Flooding continues in cottage country and with a rainy forecast, water levels are expected to rise even higher Water levels on the Red River and Roseau River are expected to continue their rise, but levels should not breach the banks of any spots along the waterways. The levels are forecast to peak between Oct. 11 and 12, and the Red River Floodway is not expected to be put into use at this time.

Potent ' BOMB CYCLONE ' strikes Atlantic Canada . "Heavy downpours can cause flash floods and water pooling on roads," warns Environment Canada . Localized flooding in low-lying areas is possible. Significant power outages possible.

Widespread warnings covered much of the Maritimes on Thursday as the first weather bomb of the season brought heavy rain and damaging winds to the region, which caused localized flooding and terrifying power line explosions.

This storm, which officially reached "bomb cyclone" status by dropping 24 millibars in pressure in 24 hours, was much weaker than the strength of post-tropical storm Dorian last month, but still targeted areas that were hit hard and left vulnerable back in September.

A " bomb cyclone " or "weather bomb " is an unofficial term for what is known as explosive cyclogenesis, according to BBC Weather. The storm is forecast to undergo rapid cyclogenesis over the Atlantic Ocean, and current projections show areas north of New York as having the highest risk

"We get strong winds like this in Atlantic Canada a few times a year," explains Weather Network meteorologist Dr. Doug Gillham, "but usually it happens in the winter when the leaves are off the trees." Leaves add more wind resistance and add weight. That, combined with the fact that several trees were likely weakened by the impact from Dorian caused numerous branches to pull apart power lines, leading to explosions.

The same system caused similar explosions in Maine -- an area that was also impacted by Dorian in September.

Shea Armstrong told CBC News that branches were falling off a tree near his home for about two hours, striking the power line and bursting into flames before hitting the ground.

"It was really, really loud and it's a noise that you've never heard — or at least I've never heard before in my life — just very electrical and unnatural and scary," Armstrong said.
