Meteorologists are of the view that the city of Bengaluru is likely to experience unstable weather, high humidity levels, cloudy weather, and precipitation due to the increasing strength of pre-monsoon weather conditions in Karnataka. According to meteorologists, moisture-laden winds, increased atmospheric instability, and cloud formation will favor the occurrence of thunderstorms and evening rains in Bengaluru. Bengaluru residents may also experience sudden rainfall, lightning, gusty winds, and waterlogging in certain parts of the city. This is expected to cause traffic congestion as well as delays in daily commuting due to the effect of rainfall on the roads. Meteorologists have further indicated that there will be an increase in humidity levels while temperatures will remain cool, making weather conditions uncomfortable. The development of stronger pre-monsoon activity in southern India is expected to result in increased rainfall in the coming weeks.
