The weather department and the Indian Coast Guard deployed at the Arabian Sea asked the fishermen community not to venture into the sea and urged them to return to the shore immediately.
Thunderstorms with wind speeds of 55kmph are likely to strike in some places till October 29. The depression in the Arabian Sea was created because the temperature of the sea increases after the monsoon season, especially during October, which is further intensified due to La Nina effect, according to IMD chief Shubhangi Bhute to The Times of India.
La Nina conditions began to emerge in the waters of the central equatorial Pacific Ocean in September 2025 and are expected to persist till February 2026. Currently, both the Arabian Sea and Bay of Bengal are experiencing above-average warmth, which further creates depression and supports the cyclonic development into the seas.
