Monday, June 6, 2022, 8:36 pm – The widespread risk of rain and thunderstorms covers much of Ontario until Tuesday, which poses an increased threat of localized flooding in areas where it rains the most.
Southern Ontario began stormy and wet in the second week of June, with heavy thunderstorms and torrential rains propelled by a low-pressure system moving across the Great Lakes. This caused warnings, clocks and special weather forecasts. Due to the slow flow of storms, training in their nature, the threat of localized floods is quite increased in parts of the south. The risk of storms and precipitation will continue through the night on Monday and until Tuesday morning. More about the expected impacts below.

UNTIL TUESDAY: Thunderstorms WITH STRONG WALLPAPERS PRESENT FLOOD POTENTIAL
There is an increased threat of flooding in parts of Ontario to begin this new week. A low-pressure system moved to Ontario on Monday afternoon, which led to heavy rainfall in the region, localized flooding is possible. Special weather forecasts and precipitation warnings remain in force.
Heavy rains and the risk of night thunderstorms are forecast in southern and central Ontario until Monday night and Tuesday morning.
Training thunderstorms can increase total rainfall and threaten flooding in some areas where storms continue to develop and be tracked in the same localized area.
Training thunderstorms line up one after the other and move over the same region, often leading to repeated rainfall and large accumulations, which increases the risk of localized floods.
Abundant lightning can be expected with storms.
In general, between 30-60 mm of rain is likely in the most affected areas, along the Erie coast and Corridor 401, which stretches across the northern Greater Toronto area, with higher amounts possible locally in areas where there is thunderstorms.
Most of the precipitation will be outside the area until Tuesday afternoon. As the cold front passes through the Golden Horseshoe, the winds will intensify in the late afternoon with gusts of 40-50 km / h.
LOOK AHEAD: THE RISK OF RAIN CONTINUES, NO SIGNS OF HIGH HEAT
Conditions will largely improve by Tuesday night, although the threat of passing rain at times will persist until the end of the week.
Most of the weekend looks set to be rainless, but temperatures will remain cool from the season. A few warmer days are expected in the middle of next week, but followed by lower temperatures again for next weekend.
