In this engaging discussion, Chris Fogarty, a meteorologist and program manager at the Canadian Hurricane Centre, delves into the evolving nature of hurricanes in Canada. He highlights the recent onslaught of storms like Helene and Milton, stressing the rising intensity linked to climate change. Fogarty also explains the unusual frequency of hurricanes and the complexities in forecasting their impacts. He emphasizes the importance of separating scientific facts from misinformation and the need for better public preparedness for future storms.
The recent hurricanes Helene and Milton exemplify a potentially new era of intensified storms affecting both America and Canada, indicating urgent preparedness needs.
Climate change is likely altering storm patterns and intensifying risks, necessitating strategic infrastructure planning and public awareness to mitigate future storm impacts in Canada.

Impact of Recent Hurricanes
Recent hurricanes, particularly Helene and Milton, have caused significant devastation in Florida and raised concerns about the increasing intensity of storms due to climate change. Meteorologists observed that both storms, occurring in quick succession, highlighted a pattern that could signify a new era of powerful hurricanes. The rapid intensification of Hurricane Milton, reminiscent of Hurricane Otis, showcased how warm ocean waters in October can dramatically enhance storm strength. This trend has led to a greater focus on preparedness measures and the potential for similar storms impacting Canada.
Climatic Change and Hurricane Patterns
Determining the influence of climate change on the power and frequency of hurricanes is complex, as it requires analyzing storm trends over extensive periods. While individual storms can’t be definitively attributed to climate change, scientific consensus indicates an increase in rainfall and flooding risk associated with warmer atmospheric conditions. For instance, hurricanes possess the capacity to track more slowly, exacerbating flooding issues, and human development near coastlines has intensified the impact of these storms. The changes in climate and coastal construction practices necessitate careful planning and adaptation strategies to mitigate future disaster risks.
Preparing for Future Storms in Canada
Canada's vulnerability to hurricanes, particularly in Atlantic regions, is heightened by rising sea levels and warmer ocean temperatures, contributing to an increased risk of direct hurricane impacts. Currently, historical data suggests significant storms occur in Canada approximately every 10 to 15 years, with recent events raising the possibility of more frequent occurrences. As communities develop infrastructure along coastlines, it is crucial to integrate projections that account for potential storm impacts and rising sea levels over time. Furthermore, public awareness of how local development can influence storm preparedness is essential for mitigating flooding and property damage during severe weather events.
We all watched in horror as America was pummelled by two massive storms in the span of ten days, the second of which gained intensity incredibly quickly before making landfall. Many experts have said this is the future of storms in the climate era—regardless of whether you believe climate change influences individual storms.
In Atlantic Canada, it's hurricane season now, and our meteorologists watched Helene and Milton closely, trying to determine if the factors that created two storms so close together and so destructive might apply to our own Eastern coast. So what did they learn from what Americans suffered through? How do you separate hyperbole and conspiracy from calm, rational science? And is Canada ready for the storms of the future, whatever they might look like?
