Weather patterns nationwide have experienced disruptions due to the combined impact of westerly winds and moisture left behind by Cyclone Arnab. Officials from the Department of Hydrology and Meteorology stated that the weather system formed over the Bay of Bengal and continues to direct moisture toward the country, resulting in widespread precipitation and significant snowfall in high-altitude mountain sectors. Data compiled by forecasting units indicates that moderate precipitation occurred across several locations within Koshi, Bagmati and Madhes provinces. Meanwhile, lighter showers were recorded in parts of Gandaki and Lumbini provinces. Mountainous zones experienced heavy snowfall, which authorities expect to persist until Saturday afternoon as the remaining weather system gradually diminishes. In response to the shifting weather patterns, officials released safety warnings advising residents to exercise caution. Bulletins urged the public to stay away from riverbanks due to rising water levels and potential inundation risks. Affected districts identified by authorities include Sindhupalchok, alongside other mountainous and hilly areas vulnerable to sudden weather shifts. Experts monitoring the atmospheric conditions explained that the convergence of tropical moisture and seasonal westerly air currents generated these widespread atmospheric changes. The Flood Forecasting Division continues to track the movement of the remnants, providing updates to local administrations to help mitigate potential hazards associated with the continuous precipitation and high-altitude snow.
