A spell of intense pre-monsoon weather is sweeping across Northeast India, blurring the line between seasonal showers and extreme events, as heavy rain, thunderstorms, and gusty winds batter states from Mizoram to Assam and Tripura.
The India Meteorological Department has warned of widespread rainfall across the region during the week, accompanied by thunderstorms, lightning, and gusty winds of 40 to 50 kmph, with isolated spells reaching up to 60 to 80 kmph.
Particularly intense spells are expected over Arunachal Pradesh between April 27 and May 2, and over Assam and Meghalaya from April 27 to 30, while heavy to very heavy rainfall is also forecast across several parts of Mizoram and Tripura.
On the ground, the impact is already visible. In Mizoram, rain, windstorms, and landslides over just two days have damaged 77 houses, including four that were completely destroyed.
According to the state Disaster Management and Rehabilitation Department, two school buildings, church halls, health sub-centres, an Anganwadi centre, and a public library have also been damaged.
Aizawl district reported 39 houses damaged by windstorms, while Lunglei district reported 31 houses damaged due to windstorms and landslides. Siaha district reported damage to three houses and a school, while Kolasib district also reported damage to four houses.
Heavy rainfall led to the closure of schools in nine districts, including Aizawl, Kolasib, Lunglei, and Mamit, as a precautionary measure. Rainfall data showed Aizawl recording 57.8 mm, followed by Mamit (47.5 mm), Khawzawl (35.5 mm), and Serchhip (34.5 mm) in a single day.
The Meteorological Department has further warned that heavy to very heavy rain with thunderstorms and lightning is likely over the next few days in several districts, including Aizawl, Kolasib, Mamit, Champhai, and Serchhip, along with gusty winds of up to 50 to 60 kmph in some areas.
In Assam, the impact has been immediate and disruptive. In Tinsukia district, torrential rainfall lashed Baghjan and adjoining areas, turning streets into water channels and triggering widespread waterlogging in several localities.
Markets were forced to shut early as water levels rose rapidly, damaging perishable goods and causing losses for traders. Traffic movement came to a near standstill on key roads, with vehicles stalling in submerged areas and commuters forced to take detours.
A more destructive picture has emerged from Tripura. According to a report cited by Tripura Info, a powerful spell of heavy storm, rain, and thunderstorms on April 28 caused widespread destruction to houses, infrastructure, and public utilities across multiple districts.
Data from the State Emergency Operation Centre shows that 2,037 houses were damaged across the state, including 112 fully destroyed, 329 severely damaged, and 1,588 partially damaged.
The impact was reported from districts including North Tripura, Unakoti, Dhalai, Sepahijala, West Tripura, Gomati, and South Tripura. In Kailashahar subdivision alone, 518 houses were damaged, including 26 fully, 33 severely, and 459 partially.
In West Tripura’s Sadar subdivision, 196 houses were damaged, while multiple locations reported road blockages due to fallen trees. Across the state, at least 129 electric poles were damaged, disrupting power supply in several areas.
While no deaths were reported in the April 28 storm, two persons were injured. A relief camp has been opened to shelter affected families, and financial assistance is being processed.
Cumulative data from April 1 to April 28 indicates that storms, heavy rainfall, and related incidents have already resulted in four deaths, 11 injuries, and damage to 2,323 houses across Tripura, highlighting the scale of recurring weather-related disruption even before the monsoon.
Across the region, these events point to a broader pattern. What is traditionally the pre-monsoon season is increasingly marked by short-duration, high-intensity rainfall, sudden flooding, strong winds, and landslides.
In hill states like Mizoram, this raises the risk of slope failures and structural damage, while in Assam’s floodplains and urban centres, even a few hours of rain can overwhelm drainage systems.
