Special weather statement in effect for:
Niagara Falls – Welland – Southern Niagara Region
St. Catharines – Grimsby – Northern Niagara Region
30 to 50 mm rain is expected on Thursday.
A period of moderate to heavy rain will develop Thursday afternoon and continue through Thursday night. Total of 30 to 50 mm rain is expected by Friday morning. Given the soil is already saturated, this heavy rain may result in localized flooding in low – lying and poor drainage areas. Areas further north and west will likely receive 20 to 30 mm of rain.
The current guidance also suggests a north trend of this heavy rain. As the system draws closer, this special weather statement might need to extend further north and west.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.
