Tauktae cyclone formed over Arabian Sea and developed into an extremely severe cyclonic storm hitting Gujarat coast on May 17. Cyclone Yaas was developed over Bay of Bengal & intensified severe cyclonic storm hitting Odisha coast on May 26. These two systems brought rainfall over the states as well as in western & eastern coasts.
Western disturbances are cyclonic storms originating in Mediterranean Sea and traverse across Central Asia before hitting north India. They are critical to northwest India as they act as major source of snow & rainfall during the winters.
