Brace yourself, Montreal. A "weather bomb" is coming.

An explosive cyclogenesis, the proper term for the weather phenomenon, will race up the east coast from Florida.

According to Environment Canada meteorologist Bruno Marquis, the "rapidly intensifying low pressure system" is expected to hit the Montreal area Sunday evening and last until Monday night. It's estimated that up to 50 millimetres of rain could fall over the area.

But parts of central Quebec will get hit harder.

The northern St. Lawrence River area could get soaked with 125 millimetres of rain. Marquis added that winds will be very strong and flooding is also a risk.

The rain could be torrential-like, especially if the system picks up moisture near Cuba before forming over Florida, which could add to the precipitation load, Marquis told CBC.

"Overall it's going to be quite a bit of rain over a week period."

The strong winds will blow the remaining leaves off trees, potentially clogging drains, which is something to watch out for, Marquis noted.

Weather bombs are a normal occurrence, especially in the fall due to the contrast in temperatures with the cold air descending from the north as winter approaches.
