Heavy Rain Alert Across Northeast: Flood-Hit Arunachal Faces More Rain Till July 14
The IMD has forecast intense rainfall across several Northeastern states, with Assam, Arunachal Pradesh, Meghalaya and Tripura facing heightened weather risks as floods, landslides and waterlogging disrupt normal life.
GUWAHATI: The India Meteorological Department (IMD) on Wednesday forecast widespread to very heavy rainfall across several Northeastern states till July 14, with Assam, Arunachal Pradesh, Meghalaya and Tripura expected to witness intense spells of rain.
The forecast has prompted heightened weather alerts across the region at a time when parts of Arunachal Pradesh are already battling flash floods and landslides, while heavy rain has disrupted normal life in Tripura.
According to the IMD, heavy to very heavy rainfall, with extremely heavy rain at isolated places, is likely over Assam and Meghalaya on Wednesday and again during July 10-14.
Nagaland, Manipur, Mizoram and Tripura are also likely to receive heavy rainfall at isolated places during July 8-14.
The weather office has forecast isolated heavy rainfall over Arunachal Pradesh from July 10 to 14.

Flood-Hit Arunachal Faces More Rain
The fresh forecast is a matter of concern for Arunachal Pradesh, where repeated spells of heavy rain have already triggered flash floods, landslides and rockfalls in several districts.
More than 94,200 people across 26 districts have been affected by the recent weather-related disasters, according to officials.
A rockfall incident triggered by incessant rainfall was also reported from East Kameng district.
Official reports said four people have so far lost their lives in the recent wave of floods and landslides, while 21 others have been injured. Two women remain missing.
With more heavy rainfall forecast through July 14, the risk of fresh landslides, rockfalls, localised flooding and disruption of road connectivity remains a concern, particularly in vulnerable hill areas.

Orange Warning Issued for Four Tripura Districts
Tripura is also facing an intense spell of monsoon rain.
The IMD’s Meteorological Centre in Agartala issued an Orange Warning for Wednesday for West Tripura, Khowai, Dhalai and Gomati districts due to the likelihood of heavy to very heavy rainfall at isolated places.
A Yellow alert was issued for the remaining four districts, where heavy rainfall was forecast at isolated locations.
The weather office also issued a Yellow alert for all eight districts of Tripura for July 9.
For July 10, a Yellow alert was issued for West Tripura, Khowai, Sepahijala, Gomati and South Tripura districts due to the likelihood of isolated heavy rainfall.
Heavy Rain Disrupts Normal Life in Tripura
Normal life was disrupted in several parts of Tripura after heavy to very heavy rainfall began on Tuesday evening.
Waterlogging was reported from low-lying areas, while traffic movement was affected at several locations.
The continuing rainfall forecast means that areas with poor drainage and locations already experiencing waterlogging could remain vulnerable to further disruption.
Repeated heavy rain over short periods can also increase the risk of local flooding, particularly where the ground is already saturated.
Assam and Meghalaya Face Intense Rain Spells
Assam and Meghalaya are among the states expected to receive some of the most intense rainfall during the current spell.
The IMD has forecast heavy to very heavy rain, with extremely heavy rainfall at isolated places, followed by another period of intense rain during July 10-14.
The forecast raises the possibility of localised flooding and waterlogging in low-lying areas. In the hill regions of Meghalaya, prolonged intense rain can also increase the risk of landslides and disruption of road connectivity.
The actual impact will depend on the location, duration and intensity of the heaviest rainfall, as well as local river and drainage conditions.
Monsoon Covered Northeast by June 10
The Southwest Monsoon advanced into substantial parts of Northeast India on June 7, two days later than its normal onset date.
According to officials of the IMD’s Meteorological Centres in Guwahati and Agartala, the monsoon covered the entire Northeastern region by June 10.
However, the arrival of the monsoon did not translate into normal rainfall across most of the region during June.
Northeast Recorded Over 40 Per Cent Rainfall Deficiency in June
Despite the current spell of widespread rain, seven of the eight Northeastern states, with Sikkim being the exception, recorded substantial rainfall deficiency during June.
According to IMD data, the Northeastern region as a whole recorded a rainfall deficiency of more than 40 per cent during June, the first month of the four-month Southwest Monsoon season.
Sikkim was the only state in the region to record excess rainfall during the month, receiving 515.9 mm against a normal of 438.2 mm.
The sharp contrast between a rain-deficient June and the current spell of intense rainfall illustrates a significant monsoon challenge: seasonal rainfall totals alone do not fully reflect the risks faced by communities.
A region can experience an overall rainfall deficit while still facing short periods of extremely heavy rain capable of triggering flash floods, landslides and severe waterlogging.
Uneven Monsoon Pattern Raises Concern
The current situation across the Northeast highlights the uneven nature of the monsoon.
While the region recorded a major rainfall deficit in June, concentrated spells of intense rain are now causing immediate problems in several states.
Such uneven distribution can create a dual challenge. Prolonged dry periods may affect agriculture and water availability, while sudden intense rainfall can overwhelm drainage systems, destabilise slopes and trigger flash floods.
According to the forecast, the monthly average rainfall over the country as a whole during July 2026 is likely to remain below normal, at less than 94 per cent of the Long Period Average.
With heavy rainfall expected across much of Northeast India till July 14, residents in flood-prone lowlands, landslide-prone hill areas and locations already affected by recent rain will need to closely follow official weather warnings and local advisories.
