Assam's Silchar city recorded its highest-ever rainfall in a single day on June 1, 2025, receiving a massive 415.8 mm of rain in just 24 hours. This breaks a 132-year-old record of 290.3 mm set back in 1893, according to data from the India Meteorological Department (IMD). The deluge was part of a broader weather pattern affecting the entire northeast, driven by cyclonic circulations and a low-level trough extending from East Uttar Pradesh to Arunachal Pradesh.

Silchar, Assam's second-largest city, was already known for its vulnerability after the devastating floods of 2022, when a dyke breach at the Barak River submerged 90 percent of the town. The latest record rainfall has once again raised alarms about flood preparedness in the region.

Heavy rains have triggered floods and landslides across Manipur, Tripura, Sikkim, Mizoram, Meghalaya, and Arunachal Pradesh. Over the last three days, at least 34 people have lost their lives. Mizoram reported 1,102 percent above-normal rainfall on May 31, while Meghalaya’s Cherrapunjee and Mawsynram recorded over 770 mm of cumulative rain in five days. The single highest one-day rainfall was seen in RKM Sohra on May 30, with 378.4 mm.

In Manipur, overflowing rivers have affected more than 19,000 people and damaged over 3,000 homes. Tripura has seen more than 10,000 people impacted by flash floods, while ten districts in Meghalaya remain under alert due to landslides and waterlogging. With the monsoon season just beginning, authorities and residents are bracing for continued severe weather as flood threats loom large across the region.
