Current System over Central Bay Of Bengal is Deep Depression strength, however, IMD has it as Depression and  we can expect them to upgrade it to Deep Depression in their subsequent Bulletins. This System is expected to strengthen further to a Cyclonic Storm within 24 hours. International Agencies have already put the System as Tropical Cyclone with 35 knots wind speed ( based on 1 minute average wind speed )

Note: IMD considers wind speed based on 3 minute Average in their System classifications.
