Monday, June 6, 2022, 8:36 PM – A widespread risk of rain and thunderstorms covers much of Ontario until Tuesday, leading to a greater threat of localized flooding in areas that see the heaviest rains.
Southern Ontario began the second week of June with storms and poplars, with heavy storms and heavy rains from a low-pressure system moving across the Great Lakes. This prompted warnings, clocks, and special weather statements. Due to the slow nature of storms, forming in their nature, the threat of localized flooding is quite high in parts of the south. The risk of storms and rain will continue until Monday night and until Tuesday morning. Learn more about the expected impacts below.

UNTIL TUESDAY: THUNDERSTORMS WITH STRONG DECALLES HAVE FLOODING POTENTIAL
There is a greater threat of flooding in parts of Ontario to begin this new week. A low-pressure system moved to Ontario on Monday afternoon, causing heavy rains across the region, possible localized flooding. Special weather warnings and rain warnings remain in effect.
Heavy rains and the risk of night storms in southern and central Ontario are forecast until Monday night and Tuesday morning as well.
Training storms could increase total rainfall and threaten flooding in some areas where storms continue to redevelop and monitor the same localized area.
Training storms line up one after the other and move around the same region, often causing repeated rainfall and high accumulations, which increases the risk of localized flooding.
With storms, large amounts of lightning can be expected.
In all, there is likely to be between 30 and 60 mm of rainfall in the hardest hit areas, along the shores of Erie and the 401 Corridor that stretches across the northern part of Greater Toronto Area, with locally higher amounts possible in areas that do see storms.
Most of the rain will leave the region on Tuesday afternoon. As the cold front climbs the golden horseshoe, the winds will intensify in the late afternoon, with gusts of 40-50 km / h.
PREVIOUS LOOK: THE RISK OF SHOWERS CONTINUES, WITH NO SIGNS OF STRONG HEAT
Conditions will improve greatly on Tuesday night, although the threat of a downpour sometimes lasts until the end of the week.
Most of the weekend looks like it won’t rain, but temperatures will stay on the cool side of the season. A couple of warmer days are expected in the middle of next week, although followed by cooler temperatures once again next weekend.
