A formidable weather system brewing over the Bay of Bengal has officially crossed inland, triggering a massive surge in monsoon activity across large swathes of peninsular, central, and northern India. The deep depression, which stayed centered over northern coastal Andhra Pradesh and adjacent southern Odisha, has begun charting a steady northwestward track across the landmass. Meteorologists indicate that although the intense system will gradually shed its strength into a regular depression while moving north-northwestward over the next 24 hours, its interaction with atmospheric currents will unleash intense rainfall across several river basins.
Landfall Near Kalingapatnam Triggers Extreme Precipitation
During the morning hours of Thursday at 8:30 AM, the center of the deep depression hovered close to the northern shoreline of Andhra Pradesh and the southern border tracts of Odisha. At that stage, the storm was positioned roughly 70 kilometers west-northwest of Kalingapatnam, 80 kilometers south-southeast of Rayagada in Odisha, 90 kilometers east-southeast of Koraput, and about 170 kilometers east-southeast of Jagdalpur in Chhattisgarh.
By the afternoon, the low-pressure system crossed the coastline near Kalingapatnam. Its landfall immediately dumped colossal amounts of rain along the coastal belt. Visakhapatnam absorbed an astonishing 278 mm of downpour, followed by Kakinada with 152.3 mm and Khammam recording 104 mm. Simultaneously, widespread rainfall accompanied by brisk surface winds has been lashing several districts across West Bengal, Bihar, and Jharkhand since September 23, 2026.
Severe Squalls and Lightning Across Eastern India
Driven by this vortex, eastern states are facing intense weather conditions. Odisha witnessed extremely heavy precipitation across several districts on September 24. Heavy rain continues to threaten the state on September 25, with isolated pockets remaining vulnerable to localized torrential bursts on September 26. In Bihar, Jharkhand, Sub-Himalayan West Bengal, and Sikkim, persistent rain and thunderstorm cycles will dominate the landscape over the coming days.
Authorities have flagged Odisha and Bihar for powerful squalls blowing at 50 to 60 kmph, with localized gusts whipping up to 70 kmph. As the core moves inland across southern Odisha, runoff into catchment zones is anticipated to cause rapid surges in local streams. An update shared on X confirmed that the system moved northwestwards at 10 kmph over six hours, placing its center over south Odisha and adjoining north coastal Andhra Pradesh by 5:30 PM on September 24, 2026.
Impact Across Andhra Pradesh, Yanam, and Chhattisgarh
North coastal Andhra Pradesh and the union territory enclave of Yanam are bracing for widespread cloudbursts and intense thunderstorm activity. Heavy rainfall is slated to persist across the region through September 25. Coastal Andhra districts must also contend with blustery surface gales reaching 50 to 60 kmph, accompanied by sudden surges hitting 70 kmph.
In Chhattisgarh, the weather system is anticipated to unleash isolated spells of exceptionally intense rainfall. The state remains on alert for strong surface winds clocking 50 to 60 kmph with gusts ascending to 70 kmph alongside intense lightning on September 25. Heavy rain spells will sweep over major parts of Chhattisgarh through September 25, creating elevated flood risks for low-lying agricultural zones.
Extended Monsoon Spells Over Madhya Pradesh and Vidarbha
Central India is set for an extended wet spell as the moisture plume travels farther inland. Widespread rainfall is forecast for eastern Madhya Pradesh and Maharashtra's Vidarbha region through September 27, while Chhattisgarh could witness persistent showers up to September 28. Western Madhya Pradesh is expected to experience extensive rainfall coverage on September 26.
Rainfall intensity projections show western Madhya Pradesh receiving heavy rain on September 25 and September 27, punctuated by very heavy downpours on September 26. Eastern Madhya Pradesh will face very heavy rainfall spells on September 25 and 26, followed by isolated heavy showers on September 27. Similarly, Vidarbha will see very heavy showers on September 25 followed by substantial rainfall on September 26.
Deluges Sweep Across Uttar Pradesh, Uttarakhand, and Himachal Pradesh
Northwest India is bracing for severe disruptions as monsoon currents interact with the advancing depression. Eastern Uttar Pradesh is likely to witness widespread rains until September 26, with very heavy falls expected on September 25 and 26, tapering to heavy spells on September 27. Western Uttar Pradesh will see widespread precipitation on September 26, alongside continuous heavy spells spanning September 25 through September 27, accompanied by persistent squally winds.
Hilly states face heightened hazards from mudslides and flash floods. Uttarakhand is set to endure heavy downpours on September 25 and 28, very heavy rain on September 27, and isolated spells of extremely heavy deluge on September 26. In Himachal Pradesh, heavy rain is projected for September 26 and 28, with very heavy falls on September 27. Both mountain states will see extensive rainfall spans between September 26 and September 28.
Disturbances Extend to Kashmir Valley and Northeastern States
Higher northern latitudes will also feel the shift in atmospheric conditions. Jammu, Kashmir, and Ladakh, along with neighboring areas, are slated to experience rain, thunderstorm activity, and lightning strikes between September 28 and September 30. Commuters along mountain passes are advised to monitor clearance updates during this timeframe.
Across the northeastern borderlands, rainy conditions will remain entrenched for days. Arunachal Pradesh is projected to receive widespread showers until September 28. Similarly, Assam and Meghalaya will endure widespread rain spells through September 28, while Nagaland, Manipur, Mizoram, and Tripura are expected to witness extensive downpours on September 27.
