Environment Canada says conditions will be favourable for the development of funnel clouds on Wednesday in the areas of Richmond Hill, Vaughan and Markham areas.

A weather advisory has been issued for these areas along with Mississauga, Brampton, Halton Hills, Milton, Burlington, Oakville and Hamilton.

Environment Canada says funnel clouds have been reported near Wheatley and Leamington, near the western shoreline of Lake Erie.

These types of funnel clouds are generated by weak rotation under rapidly growing clouds or weak thunderstorms.

Environment Canada says if conditions become favourable for tornadoes, watches and warnings will be issued
