Assam weather alert: IMD forecasts heavy rain, thunderstorms from June 5
Synopsis
Assam is bracing for a week of stormy weather, with the IMD flagging heavy rain, thunderstorms and lightning across western, central, upper and southern districts from June 5. With the Brahmaputra basin entering its annual flood-risk window, the advisory carries more than routine weight — it's an early-monsoon stress test.
Key Takeaways
The IMD has forecast widespread rain and thunderstorms across Assam over the next seven days.
Heavy rain and lightning are likely from 5 June , with peak activity between 5 June and 8 June .
Western districts including Dhubri , Kokrajhar , Barpeta , and Bongaigaon are on alert.
Upper Assam districts such as Dibrugarh , Tinsukia , and Sivasagar may see isolated heavy showers between 5 June and 7 June .
Each day's warning is valid from 8:30 am to 8:30 am the following day.
The India Meteorological Department (IMD) on 3 June issued a seven-day weather alert for Assam, forecasting widespread rainfall and thunderstorms across the state, with heavy showers and lightning likely to lash several districts from 5 June onwards. Officials said the most intense spell is expected between 5 June and 8 June, prompting advisories for residents in low-lying and flood-prone zones.
Districts on the radar
According to the Regional Meteorological Centre (RMC), Guwahati, scattered rain and thunderstorms will begin Wednesday, intensifying mid-week. Western Assam districts — including Dhubri, South Salmara-Mankachar, Kokrajhar, Chirang, Baksa, Barpeta, and Bongaigaon — are expected to face thunderstorms with lightning and isolated heavy rainfall starting 5 June.
Similar conditions have been forecast for parts of Kamrup, Nalbari, and adjoining areas.
Central and upper Assam outlook
In central Assam, districts such as Darrang, Sonitpur, Biswanath, Golaghat, and Karbi Anglong may witness thunderstorms and isolated heavy rainfall over the coming days. Hot, humid conditions are likely to persist in some pockets before rainfall activity picks up.
Upper Assam districts, including Lakhimpur, Dhemaji, Dibrugarh, Tinsukia, Sivasagar, and Charaideo, are set to receive fairly widespread rainfall with thunderstorms and lightning. Officials said isolated heavy showers are likely particularly between 5 June and 7 June.
Southern Assam warnings
The IMD has also flagged southern Assam districts — Cachar, Hailakandi, Sribhumi, and Dima Hasao — for thunderstorms with lightning and heavy rainfall at isolated locations during the forecast window.
Safety advisory
Officials urged residents to remain alert during thunderstorms and to avoid sheltering under trees or near electric poles during lightning activity. People in low-lying, flood-prone areas have been advised to track local weather bulletins closely, as sustained heavy rainfall could trigger waterlogging.
The weather office clarified that each day's warning will remain valid from 8:30 am on that day until 8:30 am the next day. The early-monsoon spell comes as Assam routinely battles seasonal flooding in the Brahmaputra basin, making accurate district-level advisories critical for disaster preparedness.
Point of View
And early-June advisories like this one are the first real test of district-level disaster readiness. The IMD's seven-day window is granular enough — the harder question is whether panchayat-level dissemination keeps pace, especially in char areas and tea-belt districts where mobile alerts often arrive after the storm.
