Severe thunderstorm watch issued, 100 mm of rain predicted in Foothills
And so the rainy season has begun. Just before noon today, Environment Canada issued a severe thunderstorm watch for the Lethbridge region.
A trough of low pressure over Southern Alberta will allow some severe thunderstorms to develop this afternoon. Such storms would have the potential to give large hail and heavy downpours. The thunderstorms are expected to persist into the evening.
A low pressure system over Central Alberta will bring heavy rain to the northern foothills once again beginning this afternoon. Total rainfall amounts of close to 100 millimetres are expected to fall by Sunday morning. Development of the low will be monitored and warnings may be expanded.
Rain and hail had already fallen in Lethbridge by 13:00 causing flooding in some residential neighbourhoods. The photos below, taken by Lethbridge News staff member Dwayne Schnell, are from Chippewa Crescent West.
Just before 14:00, a downpour hit Raymond, bringing with it a significant amount thunder and pebble-sized hail.
At shortly after 18:00, Environment Canada cancelled the severe thunderstorm watch.
