The monsoon has taken a harsh turn in the Eastern Himalayas. Sikkim and its surrounding districts are reeling under the impact of heavy rainfall, with the Teesta River breaching its embankments and flooding major roadways. National Highway 10, which serves as the primary route connecting Siliguri to Sikkim, Kalimpong, and parts of Darjeeling, is completely submerged in several places. Travel plans have been disrupted, and the region is now facing critical connectivity issues.
Teesta River Floods NH10 at 29th Mile
On the evening of July 29, the Teesta River rose rapidly following heavy rains in Sikkim’s upper reaches. By nightfall, it had breached its embankment at 29th Mile, causing significant flooding on NH10. The highway is now underwater at multiple points, completely cutting off road access between Siliguri and key hill destinations including Gangtok, Kalimpong, and Darjeeling.
Landslides Block Peshok and Bardang Routes
The Peshok Road, which connects Darjeeling to Kalimpong, is also blocked due to landslides near Teesta Bazar. A major landslide at Bardang, located between Singtam and Rangpo, has further crippled NH10. Restoration efforts are underway, but persistent rain continues to slow down progress.
Gangtok and Kalimpong Face Multiple Blockades
Gangtok, the capital of Sikkim, has seen multiple landslides across surrounding routes, especially near Tintek Khola and Kokaley. Meanwhile, a landslide at Tarkhola in Kalimpong has disrupted the vital Sevoke to Rangpo stretch. With debris scattered across roads and rain still falling, authorities are urging extreme caution for those in or traveling to these areas.
Roads to Dikchu and Surrounding Villages Severed
The Singtam to Dikchu Road in Gangtok district is completely blocked, with serious infrastructure damage in several parts. Local authorities have deployed emergency response teams and machinery, but clearance may take several days. Power cuts and communication disruptions have also been reported in nearby villages.
Weather Forecast and Advisory for Travellers
The India Meteorological Department has issued a high alert for Sikkim, Kalimpong, and Darjeeling districts. The forecast indicates more heavy to very heavy rainfall over the next two days, which may lead to further flooding and landslides. Tourists and residents are advised to avoid non-essential travel and stay updated through local authorities or verified regional platforms.
The situation continues to evolve, and all travel plans to Sikkim or the surrounding hill stations should be reconsidered until the region stabilises. Stay tuned to local updates and weather alerts to ensure safety.
