Dubai: Motorists have been urged to follow traffic rules and maintain safe distance from other vehicles as dense fog will continue to hamper visibility in coastal cities this weekend, accompanied by a slight but gradual increase in temperature.

Forecasters said the weather will be humid at night and early morning from Friday to Saturday, resulting in fog over the coastal cities of Dubai, Abu Dhabi, Sharjah and Umm Al Quwain. Visibility could drop to less than 500 metres over some areas.

“We urge motorists to drive with caution this weekend as visibility will be as bad as today’s (Thursday’s) and may drop to less than 500 metres. The fog is expected to clear by around 11am,” a forecaster from the National Centre of Meteorology told Gulf News.

Nine people were injured in a 28-vehicle pileup on Emirates Road in Dubai in the Abu Dhabi direction at 7.30am on Thursday due to poor visibility. The incident happened just days after a pileup of 44 cars happened in Abu Dhabi, injuring 22 people.

The country will be partly cloudy during the day and the amount of clouds will increase over the eastern and northern areas of the country on Friday.
