DEBRIS FLOWS: Debris flows occur when water-saturated soil in upper elevations gives way in landslide. Evidence of past debris flows can be seen dotted around the base of the Santa Catalina Mountains. But, it is fire, not water what can trigger more of them.

MONSOON RESEARCH: Monsoons come with another weather phenomenon: dust storms. They're not only a danger to traffic, but also to people's health. Dust carries bacteria and viruses that can increase susceptibility to asthma, cardiovascular problems, and other respiratory diseases.

DUST STORM APP: Monsoon related dust storms tend to be shorter in duration, but they can be more intense. It is during the monsoon when haboobs - with wind gusts up to 100 mph - are most likely to form. An app was created alert people when dust storms are near.

SAFE MOTHERHOOD: MotherToBaby is a service provided by the Organization of Teratology Information Specialists. The service informs women about products and medications they should take or avoid while pregnant or breastfeeding.
