  • Cyclone Alert
  • Cyclone Warning
  • Post Landfall Outlook
Pre-Cyclone Watch

Under this stage, warnings are issued before 72 hours. Th warning under this stage is issued by Director General of Meteorology himself.

Cyclone Alert

This is the second stage in the warning system. The warnings in this stage are issued before 48 hours in advance of the adverse weather over coastal areas.

Cyclone Warning

At this stage, the warnings are issued at least 24 hours in advance of adverse weather conditions.

Post Landfall Outlook

This is issued at least 12 hours in advance of the expected landfall.

Arabian Sea Cyclones are Weak as compared to Bay of Bengal Cyclones

The absence of landmass between the Pacific Ocean and Bay of Bengal, allows the cyclonic winds to move easily into the Bay of Bengal. This makes them stronger than those formed in Arabian Sea.
