New Delhi: The India Meteorological Department (IMD) has issued a warning of heavy rainfall over West Bengal and Odisha as a depression in the Bay of Bengal is expected to intensify into Cyclonic Storm Remal by May 25 evening. Anticipated to reach the West Bengal coasts as a severe cyclonic storm by Sunday evening, the system poses potential risks of heavy rainfall and rough sea conditions.
Forecast and Warnings
The IMD predicts heavy to very heavy rainfall in coastal districts of West Bengal and adjoining areas of North Odisha on May 26 and May 27. Additionally, rough sea conditions are expected as Remal approaches the West Bengal coast, prompting advisories for fishermen to avoid venturing into the Bay of Bengal until May 27.
Intensification and Potential Impact
According to IMD scientist Monica Sharma, the system is likely to concentrate into a depression over the central Bay of Bengal by Friday morning, intensifying into a cyclonic storm by Saturday morning. With wind speeds reaching up to 102 kilometers per hour by Sunday, Remal’s impact could extend to coastal districts of West Bengal, north Odisha, Mizoram, Tripura, and south Manipur.
Factors Contributing to Cyclone Intensity
Scientists attribute the increasing intensity and duration of cyclonic storms to warmer sea surface temperatures, a consequence of greenhouse gas emissions. Senior IMD scientist DS Pai explains that warmer sea temperatures enhance moisture levels, facilitating cyclone intensification. Madhavan Rajeevan, former secretary of the Union Ministry of Earth Sciences, notes that the current sea surface temperature in the Bay of Bengal, around 30 degrees Celsius, is conducive to cyclone formation.
Monsoon Progress and Potential Effects
While models suggest that the cyclone may not significantly affect the monsoon progress, Pai highlights potential disruptions in certain regions. Initially aiding monsoon progress over the Bay of Bengal, Remal’s detachment from the monsoon circulation could lead to moisture accumulation, potentially causing a slight delay in the monsoon’s progress in affected areas.
Conclusion
As Cyclonic Storm Remal approaches the West Bengal coast, authorities are issuing advisories and warnings to ensure preparedness and safety measures. With the cyclone expected to intensify rapidly and bring heavy rainfall, monitoring and response efforts are crucial to mitigate potential risks and safeguard vulnerable communities.
