In News:

• A deep depression in the Southwest Bay of Bengal, 800 km south of Chennai and 500 km from Nagapattinam, is expected to become Cyclone Fengal within the next 24 hours.
• It is anticipated to move north-northwest towards Tamil Nadu and Puducherry.

Key Highlights:

Cyclone Fengal Naming:

• If the depression intensifies into a cyclone, it will be named Fengal, as suggested by Saudi Arabia.
• Fengal will follow Cyclone Dana, which made landfall in Odisha in October 2024.

Cyclone Naming Process:

• Panel Members: Cyclones in the North Indian Ocean are named by a panel of 13 countries under the World Meteorological Organization (WMO) and United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP).
• Member countries include Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, the UAE, and Yemen.
• Process: Each member submits a list of 13 names, creating a rotational naming system. Names are assigned sequentially as cyclones form. Once used, a name is retired and not reused.

Cyclone Fengal’s Potential Impact:

• Fengal is expected to bring strong winds, heavy rainfall, and possible coastal flooding.
• The system’s trajectory is being closely monitored, and preparedness measures are being implemented.
