Heavy rain is likely to lash across Kerala on November 22 (Wednesday) triggered by a cyclonic circulation over interior Tamil Nadu and adjoining Kerala. The India Meteorological Department (IMD) has issued an orange alert for Pathanamthitta and Idukki districts warning of very heavy rain, and a yellow alert for the remaining districts except Kannur and Kasaragod, forecasting isolated heavy rain.
Further, another weather system is brewing over the Bay of Bengal which is likely to bring more rain to the southern peninsula, including Kerala. A cyclonic circulation is likely to emerge over the south Andaman Sea by November 25. The system is likely to intensify into a low-pressure area by November 26 and subsequently into a depression over the southeast Bay of Bengal and the adjoining Andaman Sea on November 27, according to the IMD weather bulletin.
The system is likely to trigger another round of intense spells across Kerala.
