Service Notice - September 2024: The Environment and Climate Change Canada (ECCC) CAP Service undergoes changes from time to time as the business of alerting evolves. For Fall 2024, changes are expected to include... 1) location adjustments to the new Coastal Flooding Warning Program that has been implemented back in Spring 2024, 2) Marine Warning Program and Hurricane Warning Program (for tropical cyclone information statements only) will start to use water zone splits, 3) new parameters in CAP will be created to represent the weather event's start time and the weather event's end time, 4) ECCC's initiative to upgrade the presentation of alerts into a risk-colour tiered structure is in progress. Existing elements’ values will be updated and new parameters will be added in a future release, and 5) other minor improvements and corrections.

Pour l’automne 2024, il y aura des changements incluant... 1) des ajustements aux zones du nouveau programme d’avertissement d’inondations côtières qui a été mis en œuvre au printemps 2024, 2) le programme d’avertissement marine et le programme d’avertissement des ouragans (seulement pour le bulletin d'information sur les cyclones tropicaux) commenceront à utiliser des divisions de zones maritimes, 3) de nouveaux paramètres seront créés dans le PAC pour représenter l'heure de début et l'heure de fin de l'événement météorologique, 4) l'initiative d'ECCC visant à améliorer la présentation des alertes en les classant selon une structure de niveaux de risque par couleur est en cours. Les valeurs des éléments existants seront mises à jour et de nouveaux paramètres seront ajoutés dans une prochaine version, et 5) d’autres améliorations et corrections mineures.

Strong winds that may cause damage are expected or occurring. Hazard: Very strong wind gusts of 90 to 100 km/h. Timing: Ending this morning. Discussion: A low pressure system tracking over southern Ontario is bringing a period of very strong wind gusts along the north shore of Lake Erie. Winds are expected to weaken this morning. ### Damage to buildings, such as to roof shingles and windows, may occur. Loose objects may be tossed by the wind and cause injury or damage. Utility outages may occur. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or tweet reports 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.
