Widespread rainfall has been reported in the south of India especially in Tamil Nadu, Kerala and Karnataka. The India Meterological Department (IMD) has issued red, yellow and orange alerts to some of the districts in these states. The rainfall is reportedly caused due to the low pressure area moving towards South Tamil Nadu. However, the system is expected to gradually weaken during the next 12 hours.
According to IMD: "Yesterday's well marked low pressure area over the southeast Bay of Bengal & adjoining Equatorial Indian Ocean lay over Gulf of Mannar & neighbourhood at 0300 UTC of today, the 12th December, 2024 with the associated upper air cyclonic circulation extending up to mid-tropospheric levels.
