The Indian Meteorological Department has forecast heavy rainfall, thunderstorms, and strong winds for multiple districts across Karnataka over the next few days [1].
This weather system poses a risk of disruption to local travel and infrastructure. The timing of the storms may impact agricultural activities and urban drainage systems in the affected regions.
According to the IMD, the weather pattern is being driven by a well-marked low-pressure area located over the southwest and adjoining west-central Bay of Bengal [2]. This atmospheric condition is responsible for the increased moisture and instability moving into the state.
Weather alerts specifically highlight May 16 [3] as a day for expected heavy rain and thunderstorms. The IMD said that these conditions are likely to persist over the next couple of days and through the upcoming weekend [1, 3].
While the primary focus of the alert is on Karnataka, the low-pressure system is also affecting other regions. Reports indicate that five districts in Tamil Nadu are similarly on heavy rain alert due to the same meteorological driver [2].
Local authorities in Karnataka are monitoring the situation as the system moves. The IMD said it continues to track the low-pressure area to provide updated guidance on the intensity and duration of the showers across the various districts [1].
“A low-pressure system over the Bay of Bengal is driving the wet weather.”
The convergence of a Bay of Bengal low-pressure system with regional atmospheric conditions often leads to erratic pre-monsoon or monsoon-adjacent weather in Southern India. This specific pattern increases the likelihood of flash flooding in urban centers like Bengaluru and can disrupt transport networks across the state of Karnataka.
