Warm and muggy temperatures are making conditions favourable for the development of dangerous thunderstorms according to Environment Canada.
At just after 2:30 p.m. Saturday, the weather agency issued a severe thunderstorm watch for parts of southwestern Ontario including London-Middlesex, Sarnia-Lambton, Huron-Perth and Grey-Bruce counties.
A storm system is currently making its way over parts of southern Ontario near and east of Lake Huron.
Wind gusts up to 90 kilometres per hour are possible in some areas with localized downpours between 30-50 millimetres in an hour or less.
Showers and thunderstorms are expected to develop over parts of the region late Saturday afternoon and throughout the early evening. Meteorologists say there is also a possibility for a tornado to develop. These types of storms are also capable of bringing large hail.
The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
