Tornado warnings for parts of southern Ontario have been lifted as a storm system tracks across the province.

Just before 6:30 p.m. ET, Environment Canada lifted the warnings that had been in place for Woodstock and Tillsonburg in Oxford County, along with Brantford, Simcoe, Delhi and Norfolk.

Meteorologists had been tracking a dangerous thunderstorm that they said was likely to produce a tornado. Large hail and torrential downpours were also associated with the storm that moved eastward at 60 km/h.

Environment Canada called it a "a dangerous and potentially life-threatening situation."

Many watches and warnings for severe thunderstorms were issued Wednesday across southern and eastern parts of the province, which has seen two days of hot, humid conditions.

Forecasters said thunderstorms could bring up to 50 millimetres of rain in a hour, and produce winds of 90 km/h.

People are advised take cover immediately if threatening weather approaches, Emergency Management Ontario recommends.
