Rainfall warning issued this weekend in Ottawa
Around 100 millimetres of rain could fall before Monday in some areas
Ottawa is expected to get drenched this weekend as Environment Canada issued a rainfall warning Saturday afternoon.
A weather bulletin said 100 millimetres of rain or more could fall within a 24 hour period between Sunday and Monday in some parts of the region. A low pressure system from the Atlantic coast of the U.S. is expected to move into southern Quebec and will strengthen into a "strong fall storm."
The precipitation will begin Saturday night and continue into Sunday and Monday as the system approaches.
"Strong westerly winds are also quite possible Monday in the wake of this weather system," Environment Canada said.
There is a slim chance the rainy weather will continue on Tuesday. The preliminary forecast for Halloween is calling for a high of 8 C and a low of 1 C with a 30 per cent chance of rain.
