Despite the onset of monsoon withdrawal, rains will continue in many parts of the country due to the activation of various weather systems. According to forecasts, rain, thunderstorms, and strong winds are possible from North India to Central and East India on September 18.
The India Meteorological Department (IMD) has issued updated weather information for Delhi-NCR, Uttar Pradesh, Bihar, Rajasthan, and Central India. Furthermore, heavy rain is predicted in some parts of the southern and eastern states. IMD reports that the southwest monsoon may begin withdrawing from some areas of West Rajasthan around September 19.
Rains in different parts of the country are caused by the simultaneous action of several atmospheric phenomena. A low-pressure area has formed over Surat and the Arabian Sea. The monsoon triple frontal system is also active in the northern and eastern plains. These systems help maintain moisture in the atmosphere and intensify rainfall activity in various regions.
Additionally, upper-air cyclonic circulation formed towards Southeast Asia is moving towards the North Andaman Sea. According to IMD, this could lead to the formation of a new low-pressure center around September 19, which will likely move towards the coasts of Odisha and Andhra Pradesh. This means the rainy period may continue in some parts of Eastern and Southern India in the coming days.
In Delhi-NCR and surrounding areas, the probability of precipitation remains on September 18. Heavy rain is possible in some parts of Eastern Rajasthan. In Himachal Pradesh, Jammu & Kashmir, and Punjab, rain with thunderstorms is expected in several places on September 18.
Moving to the eastern regions after North India, heavy rain is possible in parts of Bihar on September 18. The meteorological department indicates the possibility of heavy rainfall at various points in Bihar on September 18. Rain with heavy showers is also forecast in sub-Himalayan West Bengal and Sikkim in some places on September 18. Heavy rain is also expected in some areas of Odisha.
Weather in Eastern India may remain active in the following days. Rainfall activity may increase in West Bengal on the Ganges plain from September 18 to 20 and on September 23, while in Odisha it is expected from September 21 to 23. Active weather is forecasted over the Andaman and Nicobar Islands from September 18 to 23.
Meanwhile, the process of monsoon withdrawal is also beginning. According to the meteorological department, the southwest monsoon may start retreating from some areas of West Rajasthan around September 19. The retreating monsoon can bring precipitation. However, this does not mean the monsoon will immediately leave the rest of the country; rains are expected to continue in several regions of Eastern, Central, Western, and Southern India over the next few days.
In Central India, including Madhya Pradesh and Chhattisgarh, rain with thunderstorms and strong winds is possible on September 18. IMD predicts lightning and strong winds in Western Madhya Pradesh, Chhattisgarh, and surrounding areas. Wind speeds in these areas may reach 30–50 kilometers per hour. From September 18 to 23, scattered and widespread rains are expected in Western and Eastern Madhya Pradesh, Vidarbha, and Chhattisgarh. Heavy rain is also possible in some parts of Chhattisgarh, with an expected intensification of rainfall from September 20 to 23.
In West India, including Gujarat, Surat, Kachchh, and Konkan-Goa, rains may continue from September 18 to 23. In the Gujarat region, rains may intensify on September 18–19, while in Konkan and Goa, rains may become active again from September 20 to 23. Strong winds of 30–40 kilometers per hour, with gusts up to 50 kilometers per hour, are expected in some parts of Gujarat, Konkan, Goa, Surat-Kachchh, and Central Maharashtra.
In the semi-Indian part of South India, including Kerala, Mahé, and Lakshadweep, rain is forecast in various areas from September 18 to 23. On September 18, heavy rain is possible in some places in Tamil Nadu, Puducherry, Karaikal, Kerala, Mahé, and Lakshadweep. Rains may intensify in coastal Karnataka and Telangana from September 20 to 23. There is also a possibility of strong winds with thunderstorms in Tamil Nadu, Andhra Pradesh, and surrounding areas, where wind speeds may reach 40–50 kilometers per hour, with gusts up to 60 kilometers per hour.
