Delhi-NCR is likely to see rain, thunderstorms and winds reaching 30 to 40 kmph on 29 and 30 October as the impact of Cyclonic Storm Arnab and a western disturbance changes weather conditions across the region, according to the India Meteorological Department (IMD), as reported by Live Hindustan.
The weather change is expected to begin from Wednesday, with partly cloudy skies forecast over Delhi and several National Capital Region areas during the afternoon and evening. The wind direction is expected to remain northerly, while Delhi’s maximum temperature may stay around 29 to 31 degrees Celsius.
The forecast indicates a more active spell on 29 October. Delhi and adjoining NCR areas may experience partly cloudy conditions, with light rain accompanied by thunder, lightning and strong winds at several places between the afternoon and evening. Wind speeds during the period could reach 30 to 40 kmph.
The weather is expected to remain unsettled on 30 October as well. The IMD forecast cited by Live Hindustan indicates partly cloudy skies across parts of Delhi-NCR, with light rain, thunderstorms and strong winds possible from the morning through the afternoon. Winds on that day may also reach 30 to 40 kmph.
The forecast comes as Cyclonic Storm Arnab remains over the Bay of Bengal. According to the report, the storm is expected to make landfall on the Andhra Pradesh coast on Wednesday. Its influence, along with the western disturbance, is expected to bring changes to weather conditions in several states, including West Bengal, Andhra Pradesh, Odisha, Chhattisgarh, Jharkhand, Bihar and Uttar Pradesh, as well as Nepal. Moisture associated with the system is expected to contribute to the rain forecast for Delhi-NCR.
The rain is likely to bring a noticeable fall in temperatures. Delhi’s maximum temperature may decline to between 25 and 27 degrees Celsius on 29 and 30 October, with the possibility of temperatures reaching around 25 degrees. The maximum temperature is then forecast to rise to 27-29 degrees on 31 October and to around 29-31 degrees on 1 and 2 November.
The forecast also has implications for the region’s air quality. Delhi’s Air Quality Index was recorded at 197 on Tuesday evening, in the moderate category, compared with 174 on Monday. The report said that rain and stronger winds on 29 and 30 October could improve pollution levels by dispersing pollutants, although the extent of any improvement will depend on the actual intensity and distribution of rainfall and wind.
For residents, the forecast points to a short period of potentially disrupted outdoor activity, with wet roads, reduced visibility during showers and stronger winds affecting travel conditions in parts of the metropolitan region. The immediate official milestones are the expected weather change from Wednesday and the rain and wind spell forecast for 29 and 30 October.
