Guwahati: India Meteorological Department (IMD) has recorded 117.4 mm of rainfall in a single day in Guwahati on April 20 , marking the highest one-day rainfall for April since records began in 1951.
The new record surpasses the previous high of 116.5 mm recorded in 2004, underscoring the intensity of ongoing pre-monsoon activity.
The record rainfall is part of a broader spell of intense precipitation across the region. As per data from April 20, multiple locations in and around Guwahati reported heavy rainfall, including 126.5 mm at Guwahati (City) ARG, 119.5 mm at AAU-HRS, 134 mm at Gauhati University, and a striking 215.9 mm at SIRD Complex, Khanapara, indicating widespread and highly concentrated downpours.
The IMD has warned that inclement weather will persist over Assam for the next 2–3 days, with heavy to very heavy rainfall expected across several parts of the state. Weather systems, including upper air circulations over northeast Assam and adjoining regions, continue to drive the current conditions.
According to IMD’s daily report, light to moderate rainfall occurred at most places, with heavy to very heavy rain at isolated locations in the past 24 hours. The forecast also points to thunderstorms, lightning, and gusty winds reaching up to 40–50 kmph in isolated areas.
The evolving weather pattern suggests that all parts of Assam are likely to experience further intense rainfall episodes in the coming days.
In Guwahati, continued downpours are expected to worsen waterlogging, disrupt traffic, and increase the risk of tree falls and localized landslides, particularly in low-lying and hillside areas. Authorities are closely monitoring the situation, with emergency response systems on alert.
The Assam State Disaster Management Authority (ASDMA) has urged residents to remain vigilant and take necessary precautions. Commuters and travelers have been advised to avoid unnecessary movement during periods of heavy rain and plan their schedules accordingly.
Residents in vulnerable zones have been asked to stay alert for signs of flooding or landslides, while the public has been encouraged to follow official weather updates and advisories. ASDMA said the situation will be monitored continuously, with updates issued regularly for public awareness.
The record-breaking rainfall highlights a growing trend of high-intensity weather events during the pre-monsoon period, raising fresh concerns over urban resilience and disaster preparedness in Assam’s largest city.
