Winter weather in Kashmir can disrupt travel plans due to heavy snowfall, icy roads, and flight delays. The Jammu-Srinagar highway and roads to Gulmarg, Pahalgam, and Sonamarg may face closures during snowstorms. Travellers should be prepared for sub-zero temperatures, especially in January, and ensure proper heating and hot water facilities at accommodations. Snowmelt in March can create slushy conditions in lower altitudes.
