IMD weather update: Heavy rainfall forecast for South India; Monsoon withdrawal in north-western states

South Indian states are bracing for heavy rainfall from October 8-12 due to Cyclone Shakti’s remnants, with alerts issued for thunderstorms and gusty winds. Meanwhile, the southwest monsoon is retreating from Gujarat, Madhya Pradesh, and Uttar Pradesh, bringing pleasant weather but also warnings of isolated thunderstorms.
A series of weather advisories as the southwest monsoon begins to retreat from parts of India, while southern states brace for heavy rainfall due to the remnants of Cyclone Shakti.
An India Meteorological Department (IMD) update from October 9, 2025, forecasts heavy rainfall across southern and eastern India, while the southwest monsoon continues its withdrawal from the northwestern and central states. The contrasting weather is influenced by the weakening of Cyclone Shakhti’s remnants and other weather systems.

The India Meteorological Department (IMD) on Thursday, October 9, issued contrasting weather advisories for different parts of the country. While the monsoon is retreating from northwestern and central states, the southern states continue to be affected by the remnants of Cyclone Shakti and are therefore bracing for heavy rainfall.
The weather agency predicted heavy rainfall in several southern states, including Tamil Nadu, Kerala, Mahe, Andhra Pradesh and Coastal Karnataka until October 12.
Southwest monsoon withdrawal
The monsoon is steadily retreating from several parts of the country, including Gujarat, Madhya Pradesh, Uttar Pradesh and Maharashtra. In its latest bulletin, the IMD said, “Conditions are favourable for further withdrawal of the southwest monsoon from remaining parts of Gujarat; some more parts of Madhya Pradesh and Uttar Pradesh and some parts of Maharashtra during the next 2-3 days.”
The well-marked low-pressure system, a remnant of Cyclone Shakhti, remains in the west-central Arabian Sea as of the morning of October 9, with its associated cyclonic circulation extending up to 5.8 km above sea level. It is forecast to continue moving east-southeastwards over the same area and is expected to further weaken into a general low-pressure area within the next 12 hours.
Yellow alert in Kerala
The IMD issued a yellow alert in Kerala for many districts, including Pathanamthitta, Idukki, Malappuram, Wayanad, and Kannur on Thursday, predicting heavy showers. For the period of October 9–12, the state is expected to experience light to moderate rainfall and thunderstorms, with isolated areas receiving heavy rainfall.
The IMD also predicted thunderstorms with gusty wind (speed reaching 30-40 kmph) in the state during the next four days.
Mainly clear sky in Delhi
Delhi will experience mainly clear skies starting today, October 9, following a period of rain and partly cloudy conditions. Maximum temperature in the national capital is expected to range between 30 and 32°C, while minimum is likely to remain around 18-20°C.
Heavy rain and thunderstorms are expected in Tamil Nadu
The IMD predicted heavy rainfall in various districts of Tamil Nadu on Thursday as a result of the emergence of two low-pressure systems, one over the southern peninsula and another over the Kanyakumari Sea.
Heavy rain is expected in districts such as Coimbatore, Nilgiris, Erode, Dharmapuri, Krishnagiri, Tirupattur, Vellore, Ranipet, Kancheepuram, and Tiruvallur, particularly in the ghats and high-altitude regions. Thunderstorms with lightning are also expected in certain regions.
Telangana weather update
The Met Office predicted a thunderstorm for 12 Telangana districts on Thursday. Thunderstorms with lightning and strong winds are very likely to occur in isolated areas of Bhadradri Kothagudem, Khammam, Nalgonda, Suryapet, Mahabubabad, Rangareddy, Hyderabad, Medchal Malkajgiri, Mahabubnagar, Nagarkurnool, Wanaparthy, and Jogulamba Gadwal districts. Meanwhile, Hyderabad and its surrounding areas will witness a partly cloudy sky.
Light to moderate rain in Northeast India is likely
According to the IMD bulletin, Northeastern states are likely to experience light to moderate rain and thunderstorms, along with isolated heavy rainfall, till Friday. Specifically, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura are likely to experience isolated heavy rainfall on both days.
Arunachal Pradesh is also expected to have isolated heavy downpours on October 10. These weather conditions are occurring during the retreat of the Southwest Monsoon from parts of the country.
Weather forecast for South India
A period of increased rainfall activity, including isolated heavy to very heavy showers, is expected over south peninsular India for several days.
IMD Forecasts Increased Rainfall Over South Peninsular India for Next 3-4 Days

Factors influencing the weather
Several weather systems are contributing to the current conditions:
- Remnants of Cyclone Shakhti: A well-marked low-pressure area, which is the remnant of Cyclone Shakhti over the west-central Arabian Sea, has weakened and is influencing rainfall.
- Cyclonic circulations: Other cyclonic circulations over south Bangladesh and the Comorin area are also persisting and affecting weather patterns.
- Northeast monsoon: Concurrently with the withdrawal of the southwest monsoon, the northeast monsoon rainfall activity is beginning over the southeast peninsular region.
