Moderate Risk for Severe Weather Wednesday


There will be a Moderate risk for severe weather this afternoon and evening, mainly in the Niagara Region. Additional risks will exist for Prince Edward County, as well as areas to the west of Niagara.


Rain will be continuing through the day today, with the potential for severe thunderstorms to develop. The most severe storms are expected to be in the Niagara Region, and there will be a large risk for severe weather stateside. Areas to the west of Niagara may see severe thunderstorms, as well as Prince Edward County.


The main threats today will include the risk for tornadoes, flash flooding due to heavy rainfall, wind gusts up to 100 km/h, and hail 2 to 3 cm in diameter. Flooding concerns are prominent due to much of the region having already received rainfall.
