What is the story about?
The India Meteorological Department (IMD) announced that the Southwest Monsoon has progressed further into the Indian subcontinent. The monsoon has advanced into additional sections of Karnataka, Telangana, and Andhra Pradesh, the remaining parts of Tamil Nadu and Puducherry, more areas of West Bengal, and parts of Bihar. It has also pushed deeper into the southwest Bay of Bengal, along with portions of the west-central and northwest Bay of Bengal.
According to weather officials, the Northern Limit of Monsoon intersects a path that directly includes Harnai, Solapur, Hyderabad, Bhadradri Kothagudem, Kalingapatnam, Raiganj, and Madhubani. Atmospheric conditions are officially designated as favourable for a continued advance over the next one to two days into the central Arabian Sea, the rest of Maharashtra, Karnataka, Telangana, and Andhra Pradesh, as well as clusters within Chhattisgarh, Odisha, Jharkhand, Bihar, West Bengal, and Uttar Pradesh.
Regional Forecasts (June 12–17)
Driven by a complex matrix of weather systems—including a Western Disturbance active along 70°E longitude, a seasonal mean sea level trough spanning from south Punjab to south Bangladesh, and multiple lower-to-middle tropospheric cyclonic circulations—the following patterns are projected:
Northwest India & Delhi/NCR
An active wet spell fueled by the Western Disturbance will continue to influence northwest India through June 13. Fairly widespread to widespread rain is slated for Jammu-Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad and Haryana, Chandigarh & Delhi on June 12, while Himachal Pradesh will experience widespread coverage through June 13. Localised pockets of Uttarakhand and Punjab will also see continued widespread rainfall.
Severe thundersqualls producing winds of 60 to 70 kmph (gusting to 80 kmph) are anticipated across East Rajasthan, Haryana, Chandigarh & Delhi, Punjab, and West Rajasthan. Thundersqualls reaching 50 to 60 kmph are expected over East and West Uttar Pradesh. Localised hailstorms remain likely over Haryana, Chandigarh & Delhi, Himachal Pradesh, Jammu-Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad, Punjab, Uttarakhand, and West Uttar Pradesh.
Dust storm activity will explicitly impact East and West Rajasthan through June 13. Temperatures in Northwest India will hit a sharp low, dropping by 5°C to 7°C, before gradually climbing back up by 3°C to 5°C between June 13 and June 17.
For Delhi/NCR specifically, conditions will remain generally cloudy, June 12. The capital will experience two separate intervals of very light to light rain accompanied by thunderstorms and lightning—the first occurring towards the morning or forenoon, and another spell hitting towards the afternoon or evening. Strong surface winds will reach speeds of 40 to 50 kmph, gusting up to 60 kmph during these storms. Maximum temperatures will drop to a cooler 34°C to 36°C, with minimum temperatures hovering between 23°C and 25°C.
Central & East IndiaCentral India: Widespread rainfall will cover Chhattisgarh on June 12. Meanwhile, Madhya Pradesh, Vidarbha, and Chhattisgarh will transition to isolated or scattered showers through the rest of the week. Thundersqualls of 50 to 60 kmph and isolated hail are expected across East and West Madhya Pradesh.

Gangetic West Bengal, Bihar, Jharkhand, and Odisha will see their active wet spell continue through June 13 before transitioning to scattered coverage. Isolated heavy rainfall is specifically expected across Bihar, Jharkhand, Odisha, the Andaman & Nicobar Islands, and Sub-Himalayan West Bengal & Sikkim.
Northeast India
Fairly widespread to widespread rain will persist over Arunachal Pradesh, Assam & Meghalaya, and Nagaland, Manipur, Mizoram & Tripura through June 17. Isolated very heavy rainfall alerts remain active for Assam & Meghalaya and Arunachal Pradesh through June 13.
West & South Peninsular India Peninsular India: Widespread monsoon downpours are set to continue along Coastal Karnataka and Kerala & Mahe through June 17. Localised heavy to very heavy rainfall warnings are enforced for Coastal Karnataka, Kerala & Mahe, Coastal Andhra Pradesh & Yanam, Telangana, North and South Interior Karnataka, and Rayalaseema. Other southern sub-divisions will see isolated to scattered rain.
West India: Sections of Gujarat Region, Konkan & Goa, Madhya Maharashtra, and Marathwada will see isolated to scattered showers all week. However, Konkan & Goa and Madhya Maharashtra will simultaneously battle oppressive, hot and humid conditions, with the discomfort extending in Konkan & Goa through June 13.
Severe Marine Restrictions for Fishermen
Due to rough sea conditions and high-velocity winds, the IMD has issued a strict advisory ordering fishermen to completely avoid the following maritime zones:
Bay of Bengal: The Gulf of Mannar, Comorin, Sri Lanka coasts, southwest Bay of Bengal adjoining southeast Bay of Bengal, and the Andaman Sea are fully barred through June 16. The east-central and west-central Bay of Bengal remain barred through June 13.
Arabian Sea: Coastal waters along Kerala, Karnataka, Lakshadweep, and the Maldives are barred through June 13, with maritime restrictions shifting to the east-central and southeast Arabian Sea from June 13 to June 16. The Somali coast is restricted through June 16.
Continuing Heatwave Conditions
Despite the oncoming monsoon, localised heatwave warnings remain highly active in isolated pockets over Coastal Andhra Pradesh & Yanam and Vidarbha, and will persist across Telangana through June 13. Citizens in these alert areas are strongly cautioned to keep cool, stay hydrated, and avoid prolonged outdoor exertion.
