The India Meteorological Department (IMD) has issued a comprehensive seven-day weather forecast predicting widespread monsoon precipitation across large parts of the country. A fresh low-pressure system has formed over the northwestern Bay of Bengal and the adjoining coasts of West Bengal and North Odisha. Driven by this active atmospheric circulation, heavy to torrential rainfall accompanied by strong winds is expected to hit eastern, northeastern, central, and northwestern states. Even the national capital, Delhi, alongside neighboring NCR districts, is slated to receive moderate to heavy downpours. Although initial projections suggested El Nino might suppress monsoon activity this year, local weather formations have effectively counteracted those effects so far.
Torrential Rain and Extreme Weather Alerts for Eastern India
Eastern regions are expected to bear a significant impact from the current weather system. West Bengal and Sikkim will likely experience widespread precipitation continuing through August 22. Authorities have issued warnings for extremely heavy rainfall at isolated locations in Odisha and West Bengal on August 17, prompting heightened local preparedness.
Furthermore, Bihar and Jharkhand are bracing for heavy downpours between August 17 and 19. Jharkhand faces specific alerts for very heavy rain on August 17 and 18, while Bihar remains under heavy rain warnings from August 17 to 20. Odisha will witness persistent rainy spells up to August 20. Lightning strikes and thunderstorm activity are also anticipated across these eastern territories during this window.
Northwest India and Himalayan Belt Weather Forecast
Active monsoon conditions are expanding across northern plains and mountain regions. Heavy rainfall is forecast for Delhi-NCR, Haryana, Chandigarh, and Punjab on August 17 and 18. Uttar Pradesh remains under a heightened alert for three to four days due to the western end of the monsoon trough residing north of its normal position.
Western Uttar Pradesh is set to receive heavy rainfall on August 18, followed by eastern Uttar Pradesh on August 19. Thunderstorms and lightning occurrences are probable across Uttarakhand and both zones of Uttar Pradesh. In the Western Himalayan region, Jammu and Kashmir expects heavy rain, with very heavy falls at isolated places from August 17 to 19. Himachal Pradesh will encounter very heavy rainfall on August 17 and 18, followed by another spell from August 19 to 22. Uttarakhand is projected to record heavy rain continuously between August 18 and 22.
Northeastern States Monsoon Outlook
Persistent rainfall will continue across northeastern India over the coming week. Arunachal Pradesh is projected to see widespread rain through August 21, with isolated very heavy rainfall on August 17 and 18. Continuous rainfall is expected across Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura through August 22, along with frequent thunderstorms and lightning risks.
Central and Western India Weather Predictions
Monsoonal winds remain robust over central parts of India. Western Madhya Pradesh will observe widespread rainfall between August 19 and 21, with very heavy spells anticipated on August 20 and 21. Eastern Madhya Pradesh and Chhattisgarh will see ongoing rain until August 22, with isolated very heavy falls likely on August 17.
In western India, Konkan and Goa are expected to receive widespread rainfall through August 22, including heavy rain on August 17 that also covers Madhya Maharashtra. Gujarat region will witness scattered rain activity from August 17 to 22.
Southern India Wind Speeds and Maritime Warnings
Southern coastal areas are preparing for wet weather combined with strong surface winds. Coastal Karnataka is set for widespread rain until August 22, while Kerala, Mahe, and Lakshadweep will receive rain spells up to August 20. Heavy rainfall is predicted for Tamil Nadu, Puducherry, and Karaikal on August 18 and 19, alongside heavy falls in Coastal Andhra Pradesh and Yanam. Wind speeds across several southern states are likely to range from 40 to 50 km/h, with gusts reaching up to 60 km/h.
Due to rough sea conditions, IMD has advised fishermen against venturing into marine areas. Warnings are active for the Arabian Sea off the Gujarat coast until August 18. Similar advisories cover the Bay of Bengal along West Bengal, Odisha, and Bangladesh coasts until August 19, as well as the North Andhra Pradesh coast and the Andaman Sea until August 18.
El Nino Context and Long Term Climate Trajectory
At the start of the monsoon season, meteorologists anticipated El Nino might exert a suppressing effect on Indian rainfall. However, continuous low-pressure systems developing in the Bay of Bengal have successfully maintained rain patterns nationwide. Experts indicate El Nino may become fully active towards the end of the year, potentially exerting its strongest influence on the upcoming winter season.
