Bengaluru city received decent pre-monsoon showers for the second consecutive day yesterday. The city observatory recorded 35mm of rainfall, the heaviest spell in the last one month or so. The city had earlier witnessed scattered showers at the start of the month. The capital city has recorded a total of 76.1 mm of rainfall so far, against the monthly normal of 107.4mm. The months of May, June, and July have almost similar figures of monthly rainfall and start increasing from August onwards. September is the rainiest month, with about 212.8 mm of average rainfall.
A north-south trough is extending from Vidarbha to Kerala across North & South Interior Karnataka. The east-west oscillation of this trough will cause an uptick in the pre-monsoon activity during this week. More often, the pre-monsoon showers will occur in the late afternoon and early night. Bengaluru, Mysuru, Mandya, Hassan, Kolar, and Chamarajanagar are expected to have this weather activity for the next 4-5 days.
There are multiple factors joining together to enhance the pre-monsoon activity. In addition to the trough, there is a cyclonic circulation likely to form in the Bay of Bengal and reach closer to the Tamil Nadu Coast in the Southwest Bay. As the monsoon is advancing, the cross-equatorial flow is building up.
The Arabian Sea current is likely to become active well before the arrival of the monsoon over Kerala. Under the combined influence of these features, South Interior Karnataka in general and state capital Bengaluru will be lashed with pre-monsoon showers during this week. These showers may be patchy at times, leaving some parts of the city dry and drenching a few other pockets repeatedly. With the increase in pre-monsoon activity, the tech city is likely to complete its monthly quota of rainfall before the due date.
