Heavy rain fell across scattered parts of the UAE on Friday, leading to flowing valleys and significant water accumulation in low-lying areas, according to the National Centre of Meteorology (NCM).

The NCM said the unsettled conditions are expected to continue for up to three days, driven by the extension of a surface low-pressure system accompanied by an upper atmospheric low-pressure system.

On Friday, the lowest temperature dropped to 8.5°C, while maximum temperatures ranged between 25°C and 30°C. Minimum temperatures were recorded between 11°C and 17°C across the country.

Saturday’s forecast indicates partly cloudy to occasionally cloudy skies, with the formation of cumulonimbus clouds that may bring rainfall to coastal, northern and eastern regions. Winds will be northwesterly to southwesterly, moderate to active at times, and occasionally strong enough to raise dust, with speeds reaching up to 50 km/h. Sea conditions are expected to be rough in both the Arabian Gulf and the Sea of Oman.

On Sunday, weather conditions will remain generally partly cloudy, with low clouds forming over islands and some coastal and western areas. There is still a chance of rain, while humidity is expected to increase at night and into Monday morning in some western inland areas. Winds will be southwesterly to northwesterly, occasionally active, with speeds of up to 35 km/h, and seas ranging from rough to moderate.

Monday’s weather will be partly cloudy to occasionally cloudy, with clouds appearing over islands and western regions. Humidity will persist overnight and into Tuesday morning in some inland areas. Winds will shift from northeasterly to southeasterly, light to moderate in speed, becoming active at times, while sea conditions ease to light to moderate.

Tuesday is forecast to be similar, with partly cloudy skies and occasional cloud cover over islands and western areas. Humid conditions are expected overnight into Wednesday morning, with light to moderate winds and calmer seas in both the Arabian Gulf and the Sea of Oman.

Authorities continue to urge residents to remain cautious, particularly when travelling, as changing weather conditions may impact road safety and visibility.

Authorities in the UAE have urged drivers to exercise extreme caution during rain and unstable weather, warning motorists to avoid valleys and watercourses while they are flowing, regardless of how shallow they may appear.

The advisory comes as part of nationwide efforts to curb road accidents during adverse weather, when poor visibility, slippery roads and sudden water build-up significantly increase risks.

Abu Dhabi Police stressed that driving into flooded valleys is a serious traffic violation, carrying a Dh2,000 fine, 23 black points, and vehicle impoundment for 60 days.

Motorists have been advised to check weather updates before heading out, stay away from areas where water accumulates or flows, and strictly follow instructions issued by authorities.

Drivers are also urged to reduce speed, keep safe distances between vehicles and avoid all distractions. Abu Dhabi Police warned against using mobile phones while driving, including filming, and reminded motorists to follow speed limits, road signs and electronic message boards at all times.

Staying alert and following safety guidance, police said, is key to protecting lives during severe weather conditions.

Dubai has announced remote working for all government entities on Friday, December 19, as unstable weather conditions are forecast across the UAE. The private sector has also been urged to follow suit in the interest of public safety.

The directive was issued by Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai, Deputy Prime Minister, Minister of Defence and Chairman of the Executive Council of Dubai.

“The decision applies to all Dubai government employees, except for roles that require on-site presence at the workplace,” Sheikh Hamdan said in a post on X, adding that the move aims to ensure everyone’s safety amid the changing weather conditions.

Meanwhile, Global Village announced it will temporarily close its doors from December 18 until further notice due to the evolving weather situation, with other public outdoor venues also suspending operations as a precaution.

The Hatta Winter Festival will also remain closed on Thursday and Friday as a precaution, with police increasing patrols and emergency preparedness across the area.

Emirates Airlines has urged passengers travelling from Dubai on Thursday and Friday to arrive at the airport at least four hours before departure, warning that unstable weather could impact road access and airport operations.
