A severe thunderstorm watch has been issued by Environment Canada for Ottawa-Gatineau and surrounding areas, effective March 16, 2026. This alert comes just days before the official start of spring, highlighting the unpredictable nature of weather patterns in the region.
Conditions are currently favorable for the development of severe thunderstorms, which may produce strong wind gusts, large hail, and heavy rain. A sharp cold front is moving through the area, contributing to the potential for severe weather.
The watch covers several areas, including Brockville, Cornwall, and La Pêche. Residents are advised to remain vigilant as the storm could bring wind gusts of up to 90 km/h in southern Prince Edward County and 80 km/h in the Kingston-Belleville area.
In addition to high winds, the storm is expected to produce heavy rain, hail, and lightning. Local utility outages are possible, and driving conditions may become difficult as the storm progresses.
Damage to roofs, fences, branches, and soft shelters is also a concern, as the severe weather could lead to hazardous conditions. Environment Canada emphasizes that watches indicate the possibility of severe weather, while warnings signify that severe weather is occurring or imminent.
As the day progresses, temperatures in Ottawa are expected to reach 14°C by 5 p.m., a stark contrast to the 0°C forecast for 5 a.m. on the same day. Following the storm, temperatures are projected to drop to -5°C by 5 a.m. on March 17, 2026.
Additionally, snow squalls may bring 2 to 5 cm of snow overnight into Tuesday, further complicating conditions in the region.
Officials urge residents to prepare for potential impacts and stay updated on the latest weather information. Details remain unconfirmed regarding the exact timing and severity of the storms, but observers are closely monitoring the situation.
