Solution
| Date / Period | Region / State Affected PNG | Type of Extreme Rainfall Event | Impact / Description |
| Early June | Kerala / Coastal Karnataka | Onset of Southwest Monsoon / Heavy Downpour | Vigorous monsoon onset brought heavy spells, causing waterlogging in low-lying coastal areas. |
| Late June | Assam / Arunachal Pradesh | Continuous Heavy Rains & River Flooding | Brahmaputra and its tributaries crossed danger marks, flooding extensive districts in the Northeast. |
| Mid-July | Himachal Pradesh / Uttarakhand | Cloudbursts & Flash Floods | Intense localized cloudbursts triggered severe landslides, blocking mountain highways and damaging bridges. |
| Early August | Maharashtra (Mumbai / Konkan) | Torrential Rains / Continuous Downpour | Heavy continuous spells led to suburban railway disruptions and localized waterlogging in Mumbai. |
| Late August | Gujarat / Saurashtra | Cyclonic Depression / Heavy Rainstorms | Deep depression from the Arabian Sea caused widespread heavy rainfall and inundation. |
| Mid-September | Telangana / Andhra Pradesh | Intense Low-Pressure System | Heavy downpours caused reservoir water levels to rise rapidly, submerging agricultural fields. |
| Late October | Tamil Nadu (Chennai coast) | Northeast Monsoon Onset / Heavy Coastal Rains | Active northeast monsoon showers brought heavy overnight downpours, causing urban flooding. |
| November | Coastal Andhra Pradesh / Odisha | Cyclonic Storm / Severe Rain and Winds | A post-monsoon cyclonic system brought gale-force winds and heavy torrential rain near coastal belts. |
Conclusion:
- Seasonal Shift of Rainfall: Extreme rainfall events migrate geographically in sync with the monsoon cycles—concentrating in the Northeast and Western Ghats during the Southwest Monsoon (June to September) and shifting to the southern peninsular coasts (such as Tamil Nadu and Andhra Pradesh) during the Northeast Monsoon and post-monsoon cyclone season (October to December).
- Vulnerability of Regions: Mountainous northern states (like Himachal Pradesh and Uttarakhand) are highly susceptible to cloudbursts and flash floods, while coastal and low-lying urban centers face severe risks of waterlogging and riverine inundation.
- Impact & Management: These recurring extreme weather events highlight the critical need for robust disaster preparedness, accurate early-warning meteorological systems, and climate-resilient infrastructure to safeguard lives, agriculture, and property across the country.
