Weather in Assam Today: Heavy Rain with Thunderstorm and Lightning Alert for Next 24 Hours – IMD Forecast for Guwahati and Northeast India

Weather in Assam Today: IMD Issues Alert for Heavy Rain, Thunderstorms, and Lightning Across Northeast India

As April 2026 draws to a close, the people of Assam and the broader Northeastern region continue to experience a significantly cooler and wetter pre-monsoon season than usual. The intense summer heat that typically grips the region during Bohag (the Assamese month spanning late April to late May) has been largely held at bay by persistent rainfall since the end of Chot. While this has provided welcome relief from soaring temperatures, frequent heavy downpours have also triggered localized waterlogging and issues resembling artificial flooding in low-lying urban and rural areas.

According to the latest forecast issued by the Regional Meteorological Centre in Borjhar, Assam, on Sunday, the next 24 hours are likely to bring more unsettled weather across the state and neighboring Northeastern states.

Light to moderate rainfall is expected in many parts of Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur, and Tripura. Several districts in Mizoram may also see light showers accompanied by minor temperature fluctuations. Importantly, the forecast highlights a high probability of thunderstorms, lightning, and gusty winds in these areas.

In the state capital Guwahati and its surrounding regions, the sky is expected to remain predominantly cloudy, with a strong likelihood of heavy showers. The maximum temperature in Guwahati is predicted to hover around 29°C, while the minimum is likely to be 23°C. This represents a comfortable range compared to the scorching highs often recorded in previous years.

Here is the detailed temperature forecast for major districts in Assam:

Dibrugarh: Maximum 26.6°C, Minimum 19.4°C
Tezpur: Maximum 27.6°C, Minimum 20.0°C
Silchar: Maximum 28.8°C, Minimum 20.4°C
Jorhat: Maximum 26.0°C, Minimum 18.3°C
Lakhimpur: Maximum 28.4°C, Minimum 18.8°C

These cooler temperatures, combined with high humidity from ongoing rains, are creating muggy conditions that many residents describe as refreshing yet challenging for outdoor activities.

Why Assam is Seeing Prolonged Rainfall This April 2026

The current weather pattern in Assam is part of a broader active phase over Northeast India. Upper air cyclonic circulations and moisture-laden winds from the Bay of Bengal have been fueling widespread rain and thunderstorm activity since late March. The India Meteorological Department (IMD) has noted fairly widespread to widespread light to moderate rainfall accompanied by lightning and gusty winds (30-50 kmph, with isolated higher speeds) across the region.

Isolated heavy rainfall events are also possible, particularly over Arunachal Pradesh, Assam, and Meghalaya in the coming days. This aligns with seasonal trends where pre-monsoon showers often intensify before the full arrival of the southwest monsoon.

Recent weeks have already seen several spells of intense rain, leading to minor disruptions. While no major widespread damage has been reported so far, low-lying areas in urban centers like Guwahati have experienced temporary waterlogging, affecting traffic and daily commutes. Farmers in rural districts have voiced concerns over excess moisture impacting standing crops.

Impact on Agriculture and Daily Life in Assam

Assam’s economy is heavily dependent on agriculture, with rice, tea, vegetables, and maize being key crops. The continuous rainfall since the end of March has helped maintain soil moisture but excess water in some fields has raised fears of waterlogging and delayed sowing or transplanting activities.

Excess pre-monsoon rains have already begun affecting summer crops, particularly vegetables and field crops like maize in several districts. Prolonged wet conditions can promote fungal diseases and reduce yields if they persist. Government agricultural agencies have started issuing advisories to farmers, recommending proper drainage management and protective measures for nurseries.

On the positive side, the rainfall has significantly lowered the risk of forest fires and helped in maintaining river levels ahead of the main monsoon season. However, the combination of rain and thunderstorms poses risks to power lines, roads, and outdoor workers.

Daily life in Guwahati and other towns has adapted to the cloudy, showery pattern. Schools and offices continue normally, but parents and commuters are advised to carry rain gear and stay updated on local alerts. Markets see brisk sales of umbrellas, raincoats, and waterproof footwear as residents prepare for the unpredictable weather.

Thunderstorm and Lightning Safety Tips: What You Should Do

The IMD and disaster management authorities have urged the public to remain vigilant during this period of adverse weather. Thunderstorms accompanied by lightning can be dangerous, especially in open areas or under tall structures.

Here are essential do’s and don’ts during thunderstorms and lightning:

Do’s:

Move indoors to a sturdy building or a hard-topped vehicle immediately when you hear thunder.
Follow the 30/30 Lightning Safety Rule: If you cannot count to 30 between seeing lightning and hearing thunder, seek shelter. Stay indoors for at least 30 minutes after the last thunder.
Close windows and doors; unplug non-essential electrical appliances to avoid surges.
If caught outdoors, crouch low in an open area with feet together, avoiding tall trees, isolated structures, or metal objects.
Ensure children and livestock are brought indoors.

Don’ts:

Do not take shelter under tall trees, as they attract lightning.
Avoid using corded phones, taking showers, or touching running water (lightning can travel through plumbing and wires).
Stay away from doors, windows, and electrical equipment during the storm.
Never use bicycles, motorcycles, or open farm vehicles during active thunderstorms.

These simple precautions can significantly reduce the risk of lightning-related injuries, which, though rare, do occur during intense pre-monsoon activity in Northeast India.

Authorities also advise drivers to reduce speed on wet roads and watch for fallen branches or sudden water accumulation.

Broader Weather Outlook for Northeast India

The current spell is not limited to Assam alone. Neighboring states are also under similar conditions:

Meghalaya, known for its heavy rainfall records (especially in Cherrapunji), is likely to see continued showers.
Arunachal Pradesh may experience isolated heavy rainfall along with thunderstorms.
Nagaland, Manipur, Tripura, and parts of Mizoram are expected to receive light to moderate rain with possible lightning.

This widespread activity is helping moderate temperatures across the region but requires constant monitoring, especially in hilly and flood-prone districts.

The Regional Meteorological Centre has stated that the next detailed forecast will be issued in due course as the weather system evolves. Residents are encouraged to follow official IMD channels, local news, and disaster management apps for real-time updates.

How Climate Patterns Are Influencing Assam’s Weather

Assam and the Northeast are highly sensitive to climate variability. Erratic rainfall patterns, shifting onset of seasons, and increasing intensity of extreme events have become more noticeable in recent years. While this April’s rains have kept maximum temperatures in check (often 4–6°C below long-term averages in some districts), scientists note that such variability can challenge traditional farming calendars and infrastructure planning.

Longer-term forecasts suggest that the transition to the southwest monsoon could bring even heavier rainfall later in the season. This makes preparedness at the community level crucial.

Stay Informed and Prepared

As the weather in Assam remains dynamic with prospects of more rain and thunderstorms in the coming days, it is important for everyone — from urban residents in Guwahati to farmers in remote villages — to stay informed.

Download the MAUSAM app or follow the IMD Guwahati regional page for updates.
Keep emergency kits ready with flashlights, first-aid supplies, and non-perishable food.
Check on elderly family members and neighbors who may need extra assistance during stormy weather.

The recent spells of rain have brought relief from heat but also served as a reminder of the need for resilient infrastructure and adaptive agricultural practices in this beautiful yet vulnerable corner of India.
