The intense spell of rain that has been lashing Kerala for the past few days is likely to continue for four more days under the influence of a cyclonic circulation over Tamil Nadu.
The Indian Meteorological Department (IMD) issued an orange alert for seven districts from Kollam to Thrissur in the State on September 1 warning of heavy to very heavy rainfalls and a yellow alert in the remaining districts.
According to a weather bulletin issued by the IMD, a cyclonic circulation lies over south Tamil Nadu and its neighbourhood. Further, a trough now runs from the cyclonic circulation over to central Madhya Pradesh across interior Karnataka, Madhya Maharashtra, and Marathwada, extending up to 0.9 kilometre above mean sea level.
