Applied Weather Associates (AWA) has conducted numerous Probable Maximum Precipitation (PMP) studies across Canada over the past 15 years. These efforts have significantly advanced the country's extreme storm database by incorporating a broader and more comprehensive set of historical events, while applying incremental methodological improvements in storm analyses, moisture maximization adjustments, transposition techniques, and final PMP computations. Such refinements build on traditional approaches to produce more accurate, site- and region-specific estimates tailored to Canada's diverse meteorological and topographic regimes. Recent studies have placed particular emphasis on integrating detailed evaluations of climate change impacts. These assessments examine how shifting climate patterns may influence extreme rainfall intensities, snow accumulation rates, seasonal precipitation distributions, and overall storm seasonality. By drawing on climate model projections, observed trends in extreme events, and sensitivity analyses, AWA has quantified changes in PMP depths under future warming scenarios. These climate-informed updates are especially relevant for regions where snowmelt contributions and mixed-phase precipitation play critical roles in flood generation. AWA studies span the full geographic extent of Canada, covering remote northern territories such as the Yukon Territory, the expansive Prairie provinces (Alberta, Saskatchewan, and Manitoba), the rugged Rocky Mountain and Cordilleran regions in British Columbia, the boreal and shield landscapes of Ontario and Quebec, and the maritime environments of the Atlantic Coastal Provinces (New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador). This nationwide scope ensures that PMP estimates reflect local climatology, including tropical moisture intrusions in the east, Pacific frontal systems in the west, and convective outbreaks in the interior. This presentation will provide a comprehensive summary of key results from these Canadian PMP studies, including updated PMP depths by duration, area, and storm type; comparisons with legacy estimates; and insights into climate change projections for extreme precipitation inputs. It will also highlight associated advancements in supporting data, such as enhanced storm catalogs and precipitation frequency analyses. Finally, practical recommendations will be offered for dam safety applications, including how these modernized PMP values can inform spillway design, Probable Maximum Flood (PMF) calculations, risk assessments, and regulatory compliance in a changing climate. These findings underscore the importance of ongoing updates to PMP methodologies to enhance infrastructure resilience across Canada.
