Durham Region is under a special weather advisory due to incoming thunderstorms which could lead to the formation of funnel clouds.

Shortly before 10 a.m. on June 27, Environment Canada released a special weather statement regarding localized heavy rainfall. They expect 30 to 50 mm of rain over the course of the day as the thunderstorms slowly drift across the region.

Meteorologists cautioned the heavy rain could lead to flash flooding and large puddles on roads. The rain will reduce visibility and make roads slippery, so they cautioned drivers to “slow down, watch for tail lights ahead and be prepared to stop.”

“Heavy rainfall in combination with other weather factors, such as hail, wind and lightning will make outdoor activities unsafe,” Environment Canada said.

About an hour later Environment Canada released a weather advisory to warn the storms may cause funnel clouds. The weak air rotation under clouds can pull them down to Earth. While not dangerous on it’s own the funnel cloud could touch down into a weak tornado.

“Landspout tornadoes do not usually cause significant damage but can still be dangerous,” Environment Canada said, “They can be strong enough to topple trees, damage roofs or toss debris short distances.”

Durham isn’t the only area affected either. The advisory also extends around Lake Ontario from Clarington all the way to Niagara Falls.
