    Rapid-Fire Cyclones over the North Indian Ocean

    With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both…
