After a gap of more than a week, fog resurfaced in the state capital and other parts of Uttar Pradesh Saturday, adding to the winter chill.
The Regional Met office has predicted a long spell of fog but the snowfall in the neighbouring hill state of Uttarakhand has ceased.
The weatherman said the winter chill would intensify in the coming days, with the day temperatures also dropping to new lows.
While the district magistrate (DM) Lucknow has directed all schools to open at the new timing of 9 a.m., many parents have petitioned the district administration and the school authorities to prepone the winter vacations, specially for children below standard five, in light of the cold wave.
The visibility owing to fog has reduced to around 20-50 metres while the 'Uttari-Pachua' winds blowing across the state have led to a further reduction in temperatures. The maximum temperature in the city was 19 degrees Celsius Friday, which was five notches below the normal. The minimum temperature, for the second consecutive day continued to be at five degrees Celsius, which is two degrees below the normal.
Friday was recorded as the coldest day in the season so far, the weatherman said. Dry weather conditions have also aggravated the situation. In the coming days, mornings and late nights would witness heavy to very dense fog, the regional Met director J.P. Gupta said.
The dense fog has also crippled transport in the state. While most flights to the city have been delayed, more than six dozen trains continue to run behind their schedules. Officials said Friday that landing of flights at the Chaudhary Charan Singh international airport were only possible after 11 a.m. as there was very poor visibility.
