Oman Air's flight WY263 bound to the north Indian city of Lucknow from its hub Muscat was diverted to Delhi due to  turbulent weather, said a report.

The flight, heading to Lucknow, was diverted due to fog, reported Times of Oman, citing the sultanate's national carrier.

"WY263 MCT-LKO has diverted to Delhi due to bad weather. Consequently, the return sector will be affected by this delay," came the announcement from Oman Air on its twitter account.

Near zero visibility due to dense fog is likely in the northern, central and eastern parts of India on Saturday, the weather office has warned. However, some improvement could come with a change in wind direction, the India Meteorological Department (IMD) said.

Dense fog in the national capital on Friday led to the diversion of two flights at Indira Gandhi International Airport, it stated.

The weather office has forecast dense fog in some places over Punjab, Haryana, Chandigarh and Delhi over the next 24 hours, and in Uttar Pradesh, Bihar and Madhya Pradesh over the next 48 hours.
