Service Notice – February 2026: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For 2026, changes are expected to include... 1) ECCC's initiative to introduce free-form polygons to represent the true threat area of a weather hazard is tentatively set for Spring 2026 deployment. Data changes will appear in CAP following this deployment and 2) other minor improvements and corrections. For more information on these changes: https://comm.collab.science.gc.ca/mailman3/hyperkitty/list/dd_info@comm.collab.science.gc.ca/ | Notification de service – février 2026: Le service du PAC d’Environnement et Changement climatique Canada (ECCC) subit périodiquement des changements à mesure que le système d’alerte évolue. Pour 2026, il y aura des changements incluant... 1) l’initiative d’ECCC visant à introduire des polygones libres pour représenter la véritable zone de menace d’un danger météorologique devrait être déployée provisoirement au printemps 2026. Des changements de données apparaîtront dans le PAC à la suite de ce déploiement et 2) d’autres améliorations et corrections mineures.

Rainfall, combined with melting snow, is expected. The frozen ground has a reduced ability to absorb this rainfall. What: Rainfall amounts of 15 to 40 mm with locally higher amounts possible due to thunderstorms. Substantial snow melt contributing to ponding on roads and low lying areas. When: Beginning this evening and ending Saturday evening. Additional information: Several rounds of showers and isolated thunderstorms are expected with the first expected to move into Ontario this evening. The rain combined with mild temperatures will likely melt much of the significant snowpack and lead to additional runoff. For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources office. Visit Ontario.ca/floods for the latest details ### Water will likely pool on roads and in low-lying areas. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.

Don't drive through flooded roadways. Watch for washouts near rivers, creeks and culverts.
