A notable shift in atmospheric conditions is setting in across India as two distinct weather systems interact over the subcontinent. A cyclonic circulation originating overseas is advancing toward Indian waters, setting the stage for fresh instability in the Bay of Bengal. Concurrently, an active Western Disturbance situated over the northern region is generating widespread wind and rain activity across the plains and hills. Weather experts anticipate that the combined influence of these developments will produce unsettled conditions over the next six days, affecting coastal belts, eastern interiors, and northwestern states with wind speeds occasionally gusting between 40 and 60 kmph.
Gulf of Thailand System to Trigger Low Pressure in the Bay of Bengal
Atmospheric tracking indicates that a cyclonic circulation currently persists over the Gulf of Thailand. This system is anticipated to intensify maritime movement over the Andaman Sea by October 11, 2026. As it progresses further northwestward, it is projected to develop into a low-pressure area over the central and adjoining Bay of Bengal by October 13. The evolution of this maritime system will extend rainfall and squally weather to coastal states including West Bengal, Odisha, and Andhra Pradesh, with weather activity also reaching into Bihar, Jharkhand, and the northeastern states.
Influence of Western Disturbance Across Northern Plains and Hills
In the northern quadrant of the country, an active Western Disturbance continues to trigger convective activity. In addition to this disturbance, smaller regional cyclonic circulations are positioned over eastern Uttar Pradesh, southern Haryana, and parts of northeastern India. The synchronization of these systems is expected to bring light to moderate rainfall, lightning, and squally winds across northwestern India between October 10 and October 15, touching states from Rajasthan and Uttar Pradesh to Punjab, Haryana, and the Himalayan belts.
Outlook for Delhi and National Capital Region
Residents across Delhi and the wider National Capital Region (NCR) can expect shifting weather patterns from October 10 to October 15, 2026. Surface wind speeds are anticipated to remain elevated above normal levels, accompanied by overcast skies and localized rain showers. While dedicated heavy rainfall warnings have not been sounded for the capital city, conditions will favor isolated precipitation, occasional lightning activity, and sudden gusts of wind during this six-day stretch.
Wind and Rain Forecast for Haryana, Punjab, and Chandigarh
Across Haryana and Chandigarh, sporadic precipitation is anticipated from October 10 to October 15. The period spanning October 10 to October 12 is expected to see a rise in thunderstorms, accompanied by cloud-to-ground lightning and sustained winds of 40 to 50 kmph, occasionally peaking with gusts up to 60 kmph. In Punjab, scattered rainfall is projected during the same timeframe, with the most active window occurring between October 10 and October 12, when winds may clock speeds of 30 to 40 kmph and gusts could touch 50 kmph.
Weather Disruptions in Uttarakhand and Himachal Pradesh
The mountainous terrain of northern India faces more concentrated weather impacts. Uttarakhand is scheduled to witness relatively widespread showers between October 10 and October 15. A specific weather advisory highlights October 10, when thunderstorms could generate wind speeds of 40 to 50 kmph, reaching gust speeds of up to 60 kmph in open ridges and passes, alongside localized gusts of 30 to 40 kmph in other sectors. Himachal Pradesh faces similar conditions with intermittent precipitation across October 10 to October 15, with elevated risks of lightning strikes and strong winds specifically highlighted for October 10 and October 13.
Developments in Jammu and Kashmir, Ladakh, and Uttar Pradesh
Higher-altitude sectors encompassing Jammu and Kashmir, Ladakh, Gilgit-Baltistan, and Muzaffarabad will experience widespread precipitation on October 10 and October 13, flanked by isolated spells on October 11 and October 14-15. Thunderstorms accompanied by lightning are most probable on October 10 and during the October 13-14 window. Down in Uttar Pradesh, weather models indicate localized rainfall over the western districts from October 10 to October 11, while eastern Uttar Pradesh is likely to see scattered spells on October 10.
