After the ‘driest’ August in recent times, the southwest monsoon has become active in the State, triggered by the cyclonic circulations over the Bay of Bengal. Ranni in Pathanamthitta received the highest rainfall of 13 cm followed by Peerumedu in Idukki with 11 cm in the 24 hours ending 8.30 a.m. on Saturday. According to a bulletin issued by the India Meteorological Department (IMD) on Saturday, most parts of the State are likely to receive rain or thundershowers, with some districts receiving intense rainfall, till September 8.
A cyclonic circulation is likely to form over the North Bay of Bengal around Sunday. Under its influence, a low pressure area is likely to form during the subsequent 48 hours. Further, a cyclonic circulation persists over Comorin area and another over the north interior Tamil Nadu. Under the combined influence of the weather systems and a trough from Interior Karnataka to the Comorin area, the State is likely to receive isolated heavy showers, especially in south and central Kerala for the next five days.
