North India might experience its first big cold wave of the season from December 11 onwards because of fresh snow spells and rain in the hills, said private weather forecaster Skymet.

The forecaster said the cold wave could also include fog and rain in the plains which might impact road, rail and air traffic in the region.

"Winters first mega storm coming from December 11th in North India, be prepared for snow, rain and fog. Road, rail and air will be affected," Skymet CEO, Jatin Singh tweeted.

Cold weather conditions could be beneficial for the late sown wheat crop, which is yet to planted in some parts of the country including Uttar Pradesh and Punjab.

The state-run India Meteorological Department (IMD) in its forecast, too, said that temperatures over North India and in other parts of the country might remain appreciably below normal during the same period.

The met department in its annual winter weather prediction released earlier this month said that winters this year could be colder than last year but warmer than the normal across the country.
