Cyclone Maarutha


Cyclone Maarutha was the first tropical cyclone of the 2017 North Indian Ocean cyclone season. It was a relatively short-lived and weak system, but it was the first to make landfall in Myanmar in April. Although a weak system, it caused notable damage in Myanmar. Maarutha formed from an area of low pressure over the southern Bay of Bengal on April 15. The next morning, RSMC New Delhi upgraded the low pressure area to a Depression and designated it as BOB 01.

Meteorological History
