Thick formation, causing low visibility on the roads, blanketed parts of the UAE at 3am. The National Centre of Meteorology warned in its weekly weather bulletin that horizontal visibility in some areas “could drop even further at times”. The fog is expected to clear by 9am, the NCM said. Abu Dhabi Police sent out a message on social media urging drivers to exercise caution due to “reduced visibility during the fog”. Motorists were told to follow variable speed limits posted on electronic road signs when making journeys. Speed limits are typically reduced to 80 kph in the capital during spells of foggy weather in an attempt to boost safety. In its forecast, the NCM said it would be partly cloudy throughout the day, with temperatures expected to stay in the high 20s and low 30s, and humidity set to rise in the evening.
