Cyclone threat for Odisha looms as Bay of Bengal braces for potential storm

Meteorologists have warned that the La Nina condition currently present in the Pacific Ocean may lead to the formation of a cyclone in the Indian Ocean. According to weather scientists, the La Nina phenomenon can increase atmospheric moisture over the Indian Ocean and India, creating favorable conditions for tropical cyclones.

As a result, there is a possibility that a tropical cyclone may develop over the northern Indian Ocean or the Bay of Bengal. If a cyclone forms, it is likely to move towards the eastern coast of India. Since Odisha is located along India’s eastern coastline, it may also face the threat of a cyclone.

Experts further highlighted that such conditions typically arise between September and October. Given the present La Nina situation in the Pacific Ocean, its impact on the Indian Ocean is currently being closely monitored by meteorological authorities.

What is La Nina?

La Nina is a phenomenon that occurs when the sea surface temperature in the Pacific Ocean becomes significantly colder than normal. It develops when the water temperature drops by more than 0.5 degrees Celsius below the average level. This cooler condition typically persists for about two to three consecutive months.

During La Nina, cold water and air flow towards the eastern direction of the Pacific Ocean, specifically towards the coast of South America, while warm water and air currents move in the opposite direction, from east to west.

As a result of La Nina, warm air and water from the Pacific Ocean enter the Indian Ocean. This influx of warm and moist air creates favorable conditions for the formation of cyclones in the Indian Ocean. Due to India’s geographical location and the presence of moist monsoon winds, the country becomes particularly prone to the development of cyclones during this period.

When a cyclone forms in the northern Indian Ocean and especially in the Bay of Bengal, it typically moves toward the eastern coast of India, impacting states such as Odisha, Andhra Pradesh, West Bengal, and Tamil Nadu.

Impact of La Nina in India

Due to the La Nina phenomenon, India is expected to experience increased rainfall, with the monsoon becoming more intense and powerful. 

Northern and western parts of India are likely to feel stronger cold conditions. Additionally, there is a possibility of the formation of multiple cyclones over the Bay of Bengal.
