Several states have been reeling under floods caused by the onset of monsoon. Cities in different parts of Maharashtra, Gujarat, Telangana, Andhra Pradesh in south and west; and even Haryana in the north have seen flooding in recent days.
The India Meteorological Department (IMD) issued fresh weather warnings on June 25 as the monsoon gained strength across the country. Heavy rainfall, lightning, and strong winds were reported from Gujarat to Haryana, Telangana, and Maharashtra. Several states have experienced flash floods, landslides, and widespread waterlogging.
Satellite imagery analysed by India Today's OSINT team using Sentinel-1 SAR (Synthetic Aperture Radar) data revealed that large areas of land were submerged under floodwaters across the states of Gujarat, Telangana, and Maharashtra.
Very high rainfall was reported in Kurukshetra district of Haryana, and extremely heavy rainfall in Nandod and Lunawada in Gujarat over the past 48 hours. In many regions, rivers crossed danger marks and local administrations were forced to evacuate low-lying areas.
Due to limited satellite coverage, flood points could only be visualised in the western districts of Gujarat — Kutch, Morbi, Jamnagar, and Devbhumi Dwarka — where remote sensing data indicated moderate to heavy flooding.
IMD reports also indicate severe flooding in several eastern districts of the state, including Surat, Nandod, Dahod, Chhota Udepur, Panchmahal, Valsad, and Tapi. Heavy rains caused the Tapi river, which passes through the city and various creeks, to swell, resulting in waterlogging in low-lying residential areas. Some villages were completely submerged in rain water, creating a flood-like situation.
Surat city received 346 mm (or more than 13 inches) rainfall in 24 hours ending 6 am on Tuesday, while another 66 mm (nearly 2.6 inches) rainfall was registered in the subsequent 12 hours (ending 6 pm), Municipal Commissioner Shalini Agarwal said.
Several districts in Maharashtra, including Nashik, Pune, Satara, Kolhapur, Amravati, and Yavatmal, received moderate to heavy rainfall.
Flooding was reported in the Krishna and Godavari river basins in Telangana, primarily affecting the districts of Nalgonda, Adilabad, and Nizamabad.
