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.
