Guwahati Submerged by Historic April Rainfall, Flooding Cripples City
The city of Guwahati faced an unprecedented meteorological crisis as it recorded its highest-ever April rainfall in a single day, with a deluge of 117.4 mm from Sunday to Monday morning. This torrential downpour shattered the previous record of 116.5 mm set on April 6, 2004, plunging large swathes of the city into severe artificial flooding and bringing daily life to a grinding halt.
Unrelenting Thunderstorms and Nine-Hour Downpour Trigger Chaos
From Sunday night into Monday, Guwahati was battered by multiple thunderstorms and a relentless nine-hour stretch of non-stop rain. The intense precipitation began around 6:30 PM on Sunday and persisted until 3:30 AM on Monday, overwhelming drainage systems and causing widespread waterlogging, particularly in low-lying areas. Traffic came to a standstill as roads transformed into rivers, with flooding intensifying unexpectedly around 9 PM instead of subsiding.
"A robust cloud mass developed over Guwahati and adjacent regions on Sunday evening, leading to heavy to extremely heavy rainfall," explained a Met department official. The situation was exacerbated by a combination of meteorological factors, including an east-west trough extending from East Uttar Pradesh to Manipur and a cyclonic circulation over northeast Bangladesh at 0.9 km above sea level.
IMD Analysis Points to Complex Weather Systems
Senior IMD officials highlighted that the flooding was primarily driven by thunderstorms accompanied by rain, but was intensified by temporary yet devastating weather phenomena. "The presence of two other meteorological systems—a trough up to Manipur and a cyclonic circulation over northeast Bangladesh—contributed significantly to the inundation," noted an IMD representative. These systems, though short-lived, unleashed catastrophic impacts on the city's infrastructure.
Rainfall data from April 20 underscores the severity of the event, with stations across Guwahati reporting exceptionally high totals: 117.4 mm at Guwahati Airport, 126.5 mm at Guwahati (City), 119.5 mm at AAU-HRS, 134 mm at Gauhati University, and a staggering 215.9 mm at SIRD Complex in Khanapara. These figures indicate not only record-breaking rainfall but also widespread and intense activity that could persist.
Forecast Warns of Continued Inclement Weather
The IMD has issued a forecast predicting inclement weather over Assam for the next 2-3 days, with heavy to very heavy rainfall likely in various parts of the state. This raises concerns about ongoing flooding risks and potential further disruptions to life and commerce in Guwahati. Residents are advised to stay vigilant and avoid waterlogged areas as recovery efforts begin amidst the challenging conditions.
As the city grapples with this natural disaster, the record April deluge serves as a stark reminder of the increasing volatility of weather patterns and the urgent need for enhanced urban planning and disaster preparedness in vulnerable regions like Northeast India.
