Forecasters have issued an alert warning for rain and fog in parts of Abu Dhabi over the coming days. The "atmospheric depression" will affect the northeast of the emirate, primarily Al Ain, according to the warning, which is in force until Monday. The first signs of the weather system will be seen on Saturday, said forecasters. Clouds will form over the northeast, the sea and islands, as well as some areas in the north and west, with possible fog on Friday and Saturday. Rain is expected from Saturday to Monday. It could be heavy in the east, said the National Centre of Meteorology (NCM). "The public is advised to take precautions, including to drive carefully and slowly when visibility is low, and to follow weather updates and information from official sources," said Abu Dhabi Media Office. It will be mostly cloudy in the UAE on Saturday, said NCM. In Abu Dhabi and Dubai, temperatures will range from the mid-20s to the low-30s with humidity potentially hitting up to 85 per cent. Overnight and into Sunday morning the humidity will linger over some coastal and internal areas, where fog is probable. Light to moderate winds will become gusty at times. On Sunday and Monday, it will again be cloudy, with a chance of rain over some northern and eastern areas.
