While popular destinations like Shimla, Manali, Dharamshala, and Dalhousie saw a short-lived rise in pollutant concentrations on festival night, atmospheric conditions normalized rapidly by the next morning. Compared to the severe smog choking neighbouring northern plains, the hill state regained clean and breathable air within hours. ## Air Quality Numbers Across Key Towns In the state capital Shimla, extensive celebrations had pushed the Air Quality Index to a high of 191 on Diwali night. However, readings dropped sharply to 61 by 11 AM on Monday. Other monitored locations showed varying levels before stabilizing: the industrial town of Baddi recorded an index of 119, Dharamshala stood at 149, Solan at 144, Manali at 88, Kullu at 79, and Kangra registered 53. Under standard air monitoring protocols, readings below 50 reflect ideal air quality, while numbers up to 100 fall into the moderate category. Following the overnight spike, pollution levels across almost all parts of the state successfully settled below the 100 mark. ## Weekly Weather Forecast And Alerts The Meteorological Centre in Shimla outlined conditions for the coming week in a bulletin issued Monday morning, forecasting intermittent light rainfall alongside sunny intervals across seven days. Authorities have issued a yellow alert for thunderstorms accompanied by light showers on November 12 and 13. Autumn conditions have also brought dense early-morning haze to valley areas, pulling visibility down to 200 metres in Mandi and 300 metres in Sundernagar. Concurrently, warm afternoon conditions lingered in plains border areas, where Una logged a maximum temperature of 32 degrees Celsius on Sunday, the highest in the state. ## Snowfall Draws Visitors To Lahaul And Spiti As November moves into its second week, high-altitude landscapes in Lahaul and Spiti continue to attract enthusiastic snow seekers. Fresh snowfall across upper elevations has prompted travellers to head towards the Baralacha La pass, situated roughly 75 kilometres away from the district administrative centre of Keylong. The mountain pass remains blanketed under a thick layer of snow, presenting dramatic vistas alongside intense cold and strong winds that deliver an exhilarating alpine experience. Even though overall visitor footfall typically experiences a seasonal decline at the beginning of November, interest in experiencing early snow remains steady. Travellers visiting the pass describe witnessing the snow-clad peaks as an unforgettable experience, leading many to actively recommend Baralacha La to other holidaymakers seeking crisp mountain landscapes. ## What this means for you The rapid clearance of air pollution alongside early winter weather directly shapes health, visibility, and travel plans across the region. - **Across India:** Travellers fleeing hazardous air in northern plains can find clean, breathable air and early winter snow in Himachal Pradesh. Anyone scheduling road trips should factor in the wet weather alert slated for November 12 and 13. - **In Himachal Pradesh:** Residents can breathe easily again as pollutant levels dropped below 100, erasing the brief festive smog spike. Drivers in Mandi and Sundernagar must stay alert during morning hours due to fog lowering visibility between 200 and 300 metres. - **For Tourists:** Visitors venturing to Baralacha La need heavy thermal clothing to withstand intense winds and biting cold across the pass. Checking road and route clearances from Keylong before covering the 75-kilometre mountain stretch is strongly recommended. - **Daily Life:** Alternating sunshine and light rain will lead to a steady drop in temperatures, signalling the need for winter preparation. Outdoor activities should be timed carefully around the thunderstorm yellow alert on November 12 and 13. ## Why this happened A concentrated burst of festive firecrackers temporarily degraded air quality across mountain towns, though strong natural dispersion enabled a rapid return to cleaner air. - **Immediate Cause:** Intensive firecracker usage during Diwali celebrations pushed Shimla index to 191 and elevated numbers across towns like Dharamshala and Solan. As celebrations ceased overnight, emission sources halted immediately. - **Atmospheric Conditions:** Mountain wind patterns and geographical openness facilitated rapid dispersion of smoke, preventing pollutants from lingering as they do in enclosed plain basins. By Monday morning, normal air currents cleared the skies, returning readings to 61 in Shimla. - **Seasonal Factors:** Incoming weather systems are generating cloud cover and occasional showers, setting up conditions for the November 12 and 13 thunderstorm alert. Concurrently, early seasonal snow at high altitudes like Baralacha La has initiated the winter cooling cycle across Lahaul and Spiti. ## Questions & Answers ### 1.
