IMD Issues Heavy Rain Alert For Sikkim And Sub-Himalayan Bengal, Meghalaya On Highest Alert
Gangtok, July 14: The India Meteorological Department has warned that heavy to extremely heavy rainfall will continue over Sikkim, Sub-Himalayan West Bengal and the Northeast for the next three to four days, with Meghalaya placed on the highest alert where isolated locations may record disastrous rainfall exceeding 20 cm.
The fresh alert comes after 24 hours of intense rainfall activity across the eastern and northeastern belt. Sub-Himalayan West Bengal and Sikkim have already received extremely heavy rainfall in the past day, while East Uttar Pradesh, Bihar, Assam, Meghalaya and Tripura recorded very heavy rains. Rainfall in the range of 7 to 11 cm was also reported from Arunachal Pradesh, Gangetic West Bengal, Himachal Pradesh and Uttarakhand.
According to the IMD, the intense and highly localised rainfall is the result of several active weather systems converging over East India.
The main monsoon trough is currently positioned along a line stretching from Sri Ganganagar in Rajasthan all the way to Manipur, keeping the entire northern and eastern belt under active monsoon conditions. Alongside it, dual cyclonic circulations are prevailing over southern Bangladesh, the northern Bay of Bengal and eastern Bangladesh, continuously feeding moisture into the region.
A secondary trough line stretching from northwestern Bihar to Manipur is adding to the instability, while a western disturbance located over central Pakistan is influencing upper air circulation over Northern India.
With the monsoon trough anchored along the northern belt, local administrations in Bihar and the northeastern states have been advised to closely monitor rising river levels and remain prepared for possible flash floods and transport disruptions over the next 72 hours.
For Sikkim and the adjoining hills of North Bengal, the warning carries particular weight. Continuous heavy rainfall in the region raises the familiar risks of landslides, road blockades and disruption along key routes, including the highways connecting the hills to the plains of Siliguri. Residents and travellers are advised to stay updated on weather bulletins, avoid unnecessary travel on vulnerable stretches, and follow instructions issued by the district administrations.
The IMD has indicated that this spell of heavy to extremely heavy rain will persist for the next three to four days before any significant change in the pattern is expected. Meanwhile, parts of West and Central India are experiencing a comparatively dry phase of the monsoon, underlining how sharply the rainfall activity has concentrated over the eastern and northeastern parts of the country.
