Not just Bengaluru, but other parts of the state, including Mysuru, Shivamogga, Hassan, Tumkur, Mandya, Mangalore, and Chitradurga, are also likely to receive rain. These summer showers in Karnataka are part of the pre-monsoon activity triggered by changing wind patterns and moisture inflow from the Bay of Bengal and Arabian Sea.
