Pre-Monsoon Activities to Continue Over Northeast India

As India moves deeper into the pre-monsoon season, rainfall activities have begun to intensify in parts of the country. However, the Northeast region continues to grapple with a significant rain deficiency despite ongoing precipitation events. Between March 1 and April 22, the all-India rainfall deficit stands at 16%, but the situation is more severe in Eastern and Northeastern states, which are facing a 36% shortfall.

Several states in the region are experiencing particularly alarming rainfall deficits. Arunachal Pradesh leads the list with a 57% deficiency, followed closely by Nagaland, Manipur, Mizoram, and Tripura—all recording a 56% shortfall.

Assam and Meghalaya are also notably deficient, with a rainfall deficit of 44%.

Despite these deficits, rain activity has not been entirely absent. Many districts have witnessed decent showers over the past 24 hours.

In Assam, Dhubri recorded 38 mm, Rangia 53 mm, North Lakhimpur 40 mm, Dibrugarh 43 mm, Tezpur 16 mm, and Silchar 27 mm. Meanwhile, Pasighat in Arunachal Pradesh received 65 mm of rainfall.

These numbers suggest active weather, but experts note that the daily average rainfall required to bridge the existing deficit remains quite high. Hence, even consistent rainfall might not be sufficient to erase the deficiency entirely in the short term.

Meteorological observations indicate that a cyclonic circulation currently persisting over eastern Assam is contributing to this active spell of weather. As a result, moderate rain with a few heavy spells is likely to continue across many parts of Northeast India over the next 3 to 4 days.

This extended wet period is expected to keep the weather pleasant, with relatively cooler temperatures and cloud cover offering respite from typical pre-monsoon heat.

However, residents are advised to stay cautious. With repeated rainfall over hilly terrains, there is a risk of localized landslides and mudslides, particularly in vulnerable regions. While severe damage is unlikely at this stage, minor disruptions cannot be ruled out, especially in areas with unstable slopes and poorly managed drainage systems.

In conclusion, while the continuation of pre-monsoon showers brings some relief and improves local weather conditions, it may not be enough to significantly alter the overall rainfall deficit.

Ongoing monitoring and preparedness will be key, particularly with the monsoon season approaching and the region’s sensitivity to weather-related hazards.
