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.

Freezing rain and rain expected Tuesday. What: Extended period of freezing rain or freezing drizzle. Rain with amounts in the 20 to 40 mm range possible. When: Beginning early Tuesday morning and ending early Wednesday morning. Additional information: A Colorado Low is expected to bring freezing rain, freezing drizzle and rain to the region. There remains considerable uncertainty regarding the track and some of the details of this system. At this point, it appears entirely possible that the precipitation could arrive in two waves with a break for several hours on Tuesday. During this break, the freezing rain may stop or change to freezing drizzle. The location of the band of freezing rain could also shift significantly should the track of this system change. Temperatures are likely to rise above the freezing mark on Tuesday in some areas outside of the Ottawa River Valley, changing the freezing rain to rain. Untreated roads may become icy and slippery. Motorists should allow extra time to get to their destination. Power outages are possible. 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. ### 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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
