Overview
A deep depression over the Bay of Bengal is forecast to intensify into a cyclone by this evening, posing a serious threat to the coastal belt of West Bengal. The India Meteorological Department (IMD) has issued a warning for the entire eastern coastline, including Kolkata, Howrah, North 24 Parganas, and the Sundarbans region.
Key Developments
- The depression, currently located off the coast of Odisha, has a central pressure of about 999 mb and sustained wind speeds of 75‑80 km/h.
- IMD predicts the system will rotate clockwise, gather moisture, and strengthen to cyclonic intensity (wind speeds > 119 km/h) within the next 12 hours.
- The Joint Typhoon Warning Center (JTWC) has classified the system as a potential tropical cyclone with a 70‑percent chance of development.
- Coastal districts are under a *Cyclone Warning* level 2, urging residents to prepare shelters and secure property.
Background & Context
The Bay of Bengal has a long history of cyclonic activity during the pre‑monsoon season. In 2023, the region experienced Cyclone Amphan, which caused widespread damage and loss of life. The current depression follows a pattern of early‑season cyclogenesis that has been observed in recent years due to warmer sea surface temperatures and favorable atmospheric conditions.
Impact & Analysis
- Flood Risk: Low‑lying areas such as North 24 Parganas and South 24 Parganas may face storm surges up to 3 m.
- Power Disruption: Electrical infrastructure could be damaged, leading to extended outages.
- Transport: Rail and road services along the coast may be suspended; ferries and boats could be grounded.
- Agriculture: Paddy fields in the delta region risk waterlogging and crop damage.
- Public Health: Increased risk of water‑borne diseases if water supplies are contaminated.
What Happens Next
- The IMD will issue hourly updates on wind speeds, pressure, and trajectory.
- Local authorities are setting up emergency shelters in affected districts.
- Residents are advised to follow instructions from the District Magistrate and to avoid traveling to low‑lying areas.
- The next IMD bulletin is scheduled for 3 pm IST, which will confirm the system’s classification and projected path.
