Hazard Highlights

Heavy Rains and Floods for Kenya’s Coast

With today’s post, Hazard Highlights takes its final bow and retires. This venue has allowed us to deliver messages important to our partners, a wide range of hazard professionals, and to the public for five-and-a-half years. Very recently, PDC launched a web-based, mobile-accessible, touch-friendly version of Disaster Alert, a worldwide real-time atlas of hazards and disasters. With that remarkable technology, which you can have live in your hands 24/7 anywhere in the world, you can stay well informed without Hazard Highlights. No download, no login, no charge, just go to and launch Disaster Alert.
