Heavy rainfall with strong winds in Delhi-NCR; Chill increases due to temperature drop

With the start of October, the weather in many regions of the country has begun to change. On Tuesday, thunderstorms, strong winds, and rain are possible in various parts of the country. These changes occur against the backdrop of the continued withdrawal of the southwest monsoon from the country.

According to IMD data, the monsoon withdrawal line moved towards the western coast, passing through Bihar, Jharkhand, Chhattisgarh, and some areas of Maharashtra on October 5.

Despite dry weather in recent days, changes are possible in Delhi-NCR on Tuesday. Rain with thunderstorms, lightning, and strong winds is forecasted in Haryana, Chandigarh, Delhi, and Punjab. Wind speeds during this period may reach 40–50 kilometers per hour.

Weather conditions may also change in the Western Himalayas. Thunderstorms and strong winds are predicted in Himachal Pradesh, Jammu and Kashmir, Ladakh, and Uttarakhand. Additionally, rain with thunderstorms and lightning flashes is expected in some parts of Uttar Pradesh. There is also a probability of thunderstorms and lightning strikes in some parts of Madhya Pradesh, Chhattisgarh, Vidarbha, Konkan, Goa, and Maharashtra.

Various atmospheric systems contribute to rainfall and thunderstorms in many parts of the country. Cyclonic movement of upper air layers persists over Bihar and adjacent territories. Furthermore, a trough has formed from West Bengal to central Maharashtra. Due to these weather systems, the activity of storms, rains, and thunderstorms may continue in Eastern and Central India. Strong winds with thunderstorms are also expected in some areas of Andhra Pradesh, Bihar, Jharkhand, Odisha, West Bengal, and Sikkim on Tuesday.

The Meteorological Department (IMD) has predicted heavy rains in some parts of South India, while stormy weather with lightning and strong winds is expected in several northern Indian states. The highest probability of precipitation in South India is observed in Kerala, South Interior Karnataka, Tamil Nadu, Puducherry, and Karaikal. Heavy rains are possible in these areas. Rain is forecasted in many places in Kerala and Maharashtra.

According to IMD data, the impact of rains will be most noticeable in South India on Tuesday. Heavy precipitation is possible in Kerala, South Interior Karnataka, Tamil Nadu, Puducherry, and Karaikal. Rain is expected in many towns and villages in Kerala and Maharashtra.

The monsoon season is drawing to a close, but rains continue in many regions of the country. Some areas are experiencing heavy precipitation, while thunderstorms and strong winds are drastically changing weather conditions. It is expected that on September 29, rains may affect areas from the mountainous states of North India to UP, Bihar, and the northeast, as well as southern parts of the country. There is a risk of heavy rainfall, storm winds, and lightning strikes in several places.

According to the meteorological department's forecasts, heavy rains are expected on September 29 in Himachal Pradesh, some parts of Northeast India, Tamil Nadu, Kerala, and South Interior Karnataka. Meanwhile, rain and thunderstorm activity may continue in Jammu and Kashmir, Ladakh, Uttarakhand, Punjab, Haryana, Delhi, Uttar Pradesh, Madhya Pradesh, Maharashtra, and Chhattisgarh.

In Uttar Pradesh, the impact of the rains that have been falling in recent days is now noticeable in temperature levels. The situation with rain and thunderstorms persists in various parts of UP. On September 29, rain, thunderstorms, and lightning are possible in Western UP, while this process may continue until September 30 in Eastern UP.

In several districts of UP, wind intensification during rainfall is predicted. Due to continuous precipitation, daytime temperatures have dropped, and a slight chill is felt in the morning and at night. Public concern is also raised by the rising water levels in rivers such as the Ganges. Rain, thunderstorms, and lightning are also expected in Delhi, Chandigarh, and Haryana on September 29. The weather in Punjab may remain similar, although a shift towards drier climate is expected in most western parts of North India from September 30.

The weather in Jammu and Kashmir, Ladakh, Himachal Pradesh, and Uttarakhand has yet to stabilize. On September 29, rain, thunderstorms, and lightning are possible in Jammu and Kashmir, Ladakh, Gilgit-Baltistan, and Muzaffarabad. Rainy and stormy weather may also persist in Himachal Pradesh. In Uttarakhand, rain and thunderstorms are forecast in several places from September 29 to October 4. These changes in the hilly terrain also affect the plains states, causing a drop in temperature and an increase in morning and nighttime cold.

In Bihar, rain, thunderstorms, and lightning are expected on September 29 and 30. In several districts of Jharkhand, Odisha, and West Bengal, rain may continue from September 29 to October 4. Rain and thunderstorms are also possible in Gangetic and Sub-Himalayan West Bengal. The weather in Odisha and Jharkhand remains active in the coming days.

The weather in the Northeastern Indian states also remains very active. In Arunachal Pradesh, rain is possible on September 29, and heavy precipitation is forecast in some areas from October 3 to 4. In Assam and Meghalaya, there is a threat of rain, thunderstorms, and lightning on September 29; some places may receive heavy rain between September 29 and 30. Rain and thunderstorms are also expected in Nagaland, Manipur, Mizoram, and Tripura on September 29, with heavy rain forecast in some areas between September 29 and 30.

The weather in several districts of Maharashtra may also deteriorate. Rain is expected in Central Maharashtra and Marathwada on September 29.

The climate in the Delhi-NCR region has been undergoing sudden changes over the last two to three days. Due to rain and cool winds, temperatures have dropped, making the weather pleasant. However, this altered climate is not long-term.

According to the current situation, the period of rain and cold in Delhi-NCR is likely to last only until tomorrow. After that, temperatures may rise again, meaning that the current coolness cannot be considered the start of a stable winter. The weather may change again in the coming days.

The cause of this sharp weather change is attributed to the influence of a deep depression over the Bay of Bengal. This system shifted towards Uttar Pradesh. Its impact caused weather changes in Delhi-NCR and other plains areas over the last two to three days. Additionally, rainfall and snowfall in the mountainous regions, where a Western Disturbance was active, influenced the weather in the plains areas.

Although there is no new Western Disturbance in the near future, the weather in the mountainous regions may gradually change, which will subsequently affect the climate of the plains areas. Regarding the monsoon situation, monsoon processes are still active in some parts of the country, so it continues to rain in different places. Nevertheless, the monsoon has moved out of Rajasthan and Delhi-NCR.

At the same time, the process of monsoon withdrawal is continuing in several other states of the country, indicating that the monsoon has not left the entire country simultaneously. The situation varies across different areas, and rain continues in some places. For residents of Delhi-NCR, it is most important to understand that the coolness of the past few days should not be considered a permanent change in weather. Although the temperature has indeed dropped due to the rains, it may rise again in the coming days.
