A low-pressure area has become active over the southwest Bay of Bengal near northern Sri Lanka and the Tamil Nadu coast. The system has developed under the influence of a persistent cyclonic circulation over the Comorin region. According to weather experts, the associated cyclonic circulation extends up to nearly 20,000 feet above sea level, and the system is likely to intensify into a depression within the next three days. This weather system is considered unusual compared to the typical pre-monsoon pattern. Usually, systems forming over the Bay of Bengal develop around the Andaman Sea and move northwestward while strengthening. However, this low-pressure area has formed much closer to Sri Lanka and Tamil Nadu. Weather models are giving mixed signals about its future movement and intensity. Some models suggest further strengthening, while others indicate it may weaken gradually. If the system develops into a depression, it is expected to move northward. Meteorologists say favorable atmospheric conditions could help it intensify further. However, past records show that most systems forming in this part of the Bay of Bengal tend to move away from the Tamil Nadu or south Andhra Pradesh coast and drift back into the sea. Later, such systems may head toward Myanmar or Bangladesh, although some weaken over the ocean itself. The impact of this system could increase rainfall activity across several parts of South India. Heavy rain is likely over the southwest and south-central Bay of Bengal, while strong cross-equatorial winds may strengthen the monsoon flow further. Weather experts believe these conditions could support an early onset of the southwest monsoon over the southeast Bay of Bengal and the Andaman Sea.
