special weather statement in effect

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.

Significant rainfall and strong winds are expected to develop on Sunday. Locations: southern and parts of eastern New Brunswick. Potential rainfall: 25 to 40 mm, possibly higher. Potential wind gusts: northerly 70 km/h. Time span: Sunday and Sunday night. Remarks: An approaching weather system forecast to track over Nova Scotia is expected to bring another period of rainfall and gusty winds to parts of southern New Brunswick. There is some uncertainty as to where the highest rainfall amounts will occur, but the potential exists for significant totals over some locations near the Fundy coast. Wet snow may mix in at times over some elevations but is not expected to accumulate. Clear storm drains and gutters of leaves and other debris in advance of the rainfall. Secure outdoor items such as patio sets, umbrellas, and garbage bins so they don’t blow around in strong winds. ### Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NBstorm@ec.gc.ca or post reports on X using #NBStorm.

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.
