Winter cold has set in, in the entire country including the Kathmandu Valley, with the fall in the temperature. The temperature in the Kathmandu Valley has already plummeted to 0 degrees Celsius and meteorologists have warned that mercury could further dip in the coming days. They have also warned of cold waves hitting different parts of the country especially in Tarai region.
Cold has relatively increased throughout the country due to current atmospheric condition and not because of a new weather system. Increase in cold in winter is usual, but the temperature has relatively gone down and frost occurs due to impact of high-pressure area as the Valley's sky is clear in night.
