The UAE will see a foggy start to Saturday and then sunshine will follow for much of the day before it gets humid again in the evening. The National Centre of Meteorology urged motorists to take all precautions and follow the traffic regulations due to deteriorating horizontal visibility. The weather bureau said visibility will be lacking at times over some internal and coastal areas especially westward, from 02:00am on Friday until 09:30am on Saturday. Humidity levels by the coast will rise on Saturday evening and into Sunday morning, allowing mist to form, the National Centre of Meteorology said. The weather bureau forecasts light to moderate winds. Temperatures are expected to reach up to 42°C in Abu Dhabi and 41°C in Dubai. It will be slight to moderate in the Arabian Gulf and in the Sea of Oman.
