Climatologist, State of Oregon
Associate Professor, Oregon State University

Variability and Trends in Extreme Precipitation Events in the Pacific Northwest

This presentation will examine the science behind extreme precipitation events in the Pacific Northwest, including atmospheric rivers, terrain-enhanced rainfall, rain-on-snow events, flooding, and other high-impact storm patterns. The session will explore how large-scale climate variability, including ENSO and Pacific decadal variability, influences extreme weather across the region. The presentation will also highlight recent research on how climate change is affecting the intensity, duration, and frequency of heavy precipitation and atmospheric river events in the western United States, and what these trends could mean for future flood and infrastructure risks in the Northwest.

Larry O’Neill is an Associate Professor in the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University, Director of the Oregon Climate Service, and Oregon’s State Climatologist. His research focuses on climate variability and hydroclimate extremes, air–sea interactions, and the processes that drive weather and climate across the Pacific Northwest and North Pacific Ocean. His work spans topics including drought, snowpack variability, atmospheric rivers, marine heatwaves, wildfire weather, and regional climate prediction, integrating observations, satellite remote sensing, and numerical modeling. Dr. O’Neill collaborates extensively with federal, state, and regional partners to improve understanding of extreme events and support climate resilience and water-resource planning across the Pacific Northwest.

Stormwater Citizen Suits: Strategies to Reduce Litigation Risk

As publicly available discharge and compliance data become more accessible, permittees face increased exposure to enforcement-driven litigation. The discussion will examine practical steps businesses can take to strengthen compliance programs, address potential violations, and reduce litigation risk in an evolving enforcement environment.
