Motorists should drive cautiously on wet roads, maintain a safe distance from other vehicles and avoid crossing flooded stretches. People should also secure loose outdoor objects when strong winds are forecast.
Weather warnings can change as conditions develop, and a state-level alert does not mean every district will receive the same amount of rainfall.
For the most relevant guidance, residents should consult official district-level forecasts and updates from the India Meteorological Department.
