Sela Pass to Tawang

⚠️ While the Sela Tunnel provides all-weather connectivity, watch for black ice on the old Sela Pass road if taking a detour, and be aware of potential acute mountain sickness (AMS) due to sudden altitude changes. Recent snowfall in late March 2026 at Sela Pass and Bumla Pass, along with IMD warnings for heavy rain in April, suggest caution, especially for early April travel. As of June 24, 2026, heavy landslides and flash floods have blocked crucial stretches of NH-13 in Papum Pare district, disrupting connectivity to western districts including Tawang. A travel advisory is in effect, urging commuters to avoid affected roads. Additionally, the India Meteorological Department (IMD) has forecast thunderstorms with lightning and heavy rain at isolated places in West Kameng (Sela Pass region) for June 25-27, 2026. Furthermore, new alerts and consultations on June 4 and June 8, 2026, have reinforced the urgent high-altitude public advisory regarding a possible Glacial Lake Outburst Flood (GLOF) from the Khangri Glacier region. Travelers are advised to avoid riverbanks along Tawang Chu and Mago Chu basins, suspend non-essential movement across high-altitude routes during heavy rainfall, and avoid crossing flooded streams or weakened bridges. As of July 26, 2026, the road via Sela Tunnel has been reported broken and may take the entire month of August to fix, depending on rainfall. The IMD has also forecast heavy rain and thunderstorms in Tawang and West Kameng from August 19, 2026. A scientific assessment on August 15, 2026, reported alarming geomorphological changes in the Khangri Glacier, including a potentially dangerous proglacial lake that could trigger a Glacial Lake Outburst Flood (GLOF) in the Mago Chu Basin, reinforcing previous advisories.
