Probable impacts due to heavy rain
The weather agency has warned that the heavy to extremely heavy rainfall may cause several disruptions and damage across affected areas. Poor visibility due to intense rain could lead to traffic congestion and temporary disruption of movement owing to waterlogging, fallen trees, or broken branches, resulting in longer travel times.

Uprooted trees may damage power lines and vulnerable structures, while kutcha houses and huts face the risk of partial damage. There is also a likelihood of flash floods, waterlogging in low-lying areas, and landslides or mudslides in hilly regions. Surface and helicopter services may be regulated, and small ships and country boats could be affected by strong winds and heavy rain. Standing crops and vegetables in the maturity stage may suffer damage, while lightning poses a threat to people and cattle in open areas.
