IMD Weather Forecast August 7, 2026

Hydrological Inflow & River Basins: Inflow into the Pamba, Manimala, Meenachil, Periyar, and Chaliyar rivers remains elevated due to sustained rainfall over Western Ghats catchments. Water levels in the Mullaperiyar Dam and Idukki Reservoir are under continuous observation by hydrometeorological engineers.

Landslide & Slope Hazards: High-range hill routes in Wayanad (Vythiri, Lakkidi), Idukki (Munnar, Peerumade), and Kannur (Ayyankunnu, Iritty) face high risks of mudslides, soil slips, and falling trees. Night travel along hilly routes remains restricted.

Coastal Swell Surge & Fishermen Ban: High swell surge waves measuring 1.1 meters to 1.4 meters with peak wave periods of 15 to 20 seconds are forecast off the Thiruvananthapuram, Kollam, and Alappuzha coastlines. A total ban on sea departures remains active due to squally winds gusting up to 60 km/h.

B. Coastal & South Interior Karnataka: Offshore Trough Impact

The active offshore trough along the West Coast continues to generate heavy to very heavy precipitation over Coastal and South Interior Karnataka on August 7.

• Coastal Karnataka (Dakshina Kannada, Udupi, Uttara Kannada): Designated under an Orange Alert for Very Heavy Rainfall (12 cm to 20 cm). Strong surface winds reaching 40 to 50 km/h gusting to 60 km/h will prevail, creating rough sea conditions and sea erosion along beaches.
• South Interior Karnataka (Kodagu, Chikkamagaluru, Shivamogga): An Orange Alert is in effect across the Malnad hill districts. Heavy watershed runoff is increasing inflows into the Netravati, Kumaradhara, Hemavati, and Cauvery river basins.

C. Central India & East Rajasthan: Bay Circulation Surge

Driven by the cyclonic circulation over the Northwest Bay of Bengal and north Odisha coast, rainbands are intensifying across East Madhya Pradesh, Odisha, and East Rajasthan on August 7:

• East Madhya Pradesh: Designated under an Orange Alert for Very Heavy Rainfall. Jabalpur, Mandla, Dindori, Balaghat, and Rewa districts are under watch for intense rain passes capable of causing rapid runoff into the Narmada River basin.
• East Rajasthan: An Orange Alert covers Kota, Baran, Jhalawar, and Udaipur districts. Heavy downpours accompanied by thunderstorms and lightning are likely.
• Odisha: An Orange Alert covers northern and coastal districts including Mayurbhanj, Keonjhar, Balasore, Bhadrak, and Kendrapara. Strong winds blowing at 30 to 40 km/h with frequent lightning strikes (vajrapat) are predicted.

D. Western Himalayas: Himachal Pradesh & Uttarakhand

The interaction of monsoonal moisture with mid-level circulations maintains an Orange and Yellow Alert watch across the Western Himalayas on August 7:

• Uttarakhand: Dehradun, Uttarkashi, Chamoli, Rudraprayag, Pithoragarh, and Nainital are under an Orange Alert for heavy to very heavy rainfall. Flash flood risks cover watersheds feeding the Alaknanda, Bhagirathi, and Mandakini rivers. Landslides remain likely along National Highway 58 (Rishikesh-Badrinath) and National Highway 109 (Rudraprayag-Kedarnath).
• Himachal Pradesh: Kangra, Kullu, Mandi, Shimla, and Sirmaur are under a Yellow to Orange Alert. Saturated hill slopes increase the likelihood of mudslides and road blockages along the Kalka-Shimla highway (NH-5).
