The main threat with these storms would be large hail and torrential downpours. Damaging winds are a lesser threat. An isolated tornado cannot be ruled out either.

Rainfall warning. Showers and thunderstorms tracking along the warm front have given rainfall amounts over 50 mm in some areas. The rain is expected to continue for much of the day contributing to rainfall amounts ranging from 50 to 70 mm across the region.
