Measuring Arizona's Dust Storms

Guest: Amber Sullins, Chief Meteorologist at ABC15

When most people think about dangerous weather, they think about hurricanes, tornadoes, or blizzards. But in the deserts of the Southwest, one of the most impactful—and often overlooked—hazards can arrive as a towering wall of dust. Today on Weather Geeks, we're joined by Amber Sullins, a longtime Arizona meteorologist who has spent her career helping people navigate everything from extreme heat and monsoon storms to the massive dust storms that have become synonymous with life in the desert Southwest. We'll talk about her journey forecasting some of the country's most unique weather, and we'll take a deep dive into the development of the new PHX-DUST scale—a groundbreaking effort designed to classify dust storms and better communicate their impacts to the public. From the science behind the scale to the challenges of translating complex research into actionable information, we'll explore how meteorologists are working to improve awareness and resilience in the face of one of Arizona's signature weather threats.
