Why This Tropical Coast Can Turn Deadly

Mozambique's coast is one of the deadliest tropical coastlines on Earth. On March 14, 2019, Cyclone Idai hit Beira — a city just 6 meters above sea level — with 220km/h winds and a 4.5-meter surge that left a 50km-wide inland lake the size of Luxembourg. It maps why drowning, not wind, killed 603 people, how the flat Zambezi and Limpopo basins trap water, and how floods bring crocodiles, cobras and disease, to record 36-day Cyclone Freddy and a hotter future.
