A yellow alert has been issued for four districts, Pathanamthitta, Kottayam, Idukki, and Ernakulam, on Thursday, warning of isolated heavy rains. According to a weather bulletin issued by the India Meteorological Department (IMD), an upper air cyclonic circulation lies over the Gulf of Mannar and the neighbourhood at 1.5 km above mean sea level. In addition, the north-south trough/wind discontinuity from cyclonic circulation over the central parts of South Madhya Pradesh to the Gulf of Mannar runs from north interior Karnataka to the Gulf of Mannar across Rayalaseema and Tamil Nadu at 0.9 km above mean sea level. This is likely to trigger rainfall activity across the State for the next four days. Meanwhile, Urumi in Kozhikode recorded very heavy rainfall of 17 cm during the last 24 hours ending at 8.30 a.m. on Wednesday, followed by Karapuzha and Kalpeta in Wayanad with 7 cm each and Pampadumpara in Idukki with 6 cm.
