Cyclone spares Bangladesh the worst
Bangladesh has largely escaped the feared damage from Cyclone Mahasen through a fortunate sequence of events.
The storm, which has now moved inland, has been downgraded to a tropical depression and is now not thought to be a threat. Airports and ports have re-opened.
However, given the history of devastating cyclones in the Bay of Bengal in which hundreds of thousands have died, why has there has been a relatively lucky escape this time?
