Dust storms and haboobs pose significant risks to transportation, air quality, and public health in Phoenix, especially during the monsoon season. Reduced visibility can lead to accidents on roadways, while high concentrations of particulate matter can exacerbate respiratory issues for vulnerable populations. The new classification system helps communicate the severity of these events, enabling better preparedness and response. Extreme storms, such as those rated Category 5, can cause widespread disruption and hazardous conditions across the region.
