Parts of southern Ontario had a loud night as thunderstorms and heavy rains continued through the overnight on Monday and pre-dawn Tuesday. Now, as the region attempts to dry off, the storm risk will shift into eastern Ontario on Tuesday.<\/p>\n

A stalled upper-level trough will bring a potential for severe, flooding storms to the Ottawa-Kingston region on Tuesday, as well as to Montreal. Some locales could see 50-80+ mm of rainfall from the slow-moving storms.<\/p>\n

The most serious danger will be if storms frequently pass over the same locations, causing rainfall totals to rapidly rise. Localized flooding, low visibility and dangerous driving conditions are all conceivable.<\/p>\n

Showers and heavy downpours may continue overnight Tuesday into Wednesday, but the bulk of the storms will stay in Quebec.<\/p>\n
