Flights operating out of Dubai and Sharjah faced cancellations and delays on Friday as unstable weather lingered across the UAE for the second day. Heavy rain along with thunder and lightning disrupted air travel and daily activities in several emirates, impacting key airports and major roads.

Emirates airline confirmed the cancellation of 13 scheduled flights from Dubai International Airport due to hazardous weather conditions. The airline noted that adverse weather on December 18 and 19 affected flight operations, causing cancellations, delays, and changes to flight schedules. Many early flights by both local and international carriers also faced significant delays or were grounded.

Passengers found themselves in a state of uncertainty as airlines attempted to manage the disruptions. Darren Taft, a traveler awaiting an Air Arabia flight to Sharjah at Phuket Airport, reported no confirmed departure time for his delayed flight. He mentioned that earlier flights had not arrived and that conditions back in Dubai were still poor, intensifying passenger anxiety.

The extreme weather began affecting Dubai on Thursday afternoon and subsequently brought heavy rain to Abu Dhabi that night. Ongoing downpours resulted in waterlogging on the roads, localized flooding in residential areas, and significant traffic congestion nationwide. Authorities advised motorists to exercise caution and anticipate delays during busy periods.

In light of safety concerns, Dubai Police advised residents to steer clear of beaches, valleys, and areas prone to flooding. Various public spots, including parks, beaches, and well-frequented attractions like Global Village, were closed temporarily. According to the Dubai Media Office, unstable weather conditions are expected to persist until Friday.

To address safety challenges, authorities activated emergency response initiatives, with Dubai's Roads and Transport Authority deploying over 300 pumps to mitigate floodwater issues and relieve traffic congestion. An orange alert was issued by the National Centre of Meteorology for Dubai, Sharjah, Fujairah, Khor Fakkan, and parts of Abu Dhabi, advising residents of perilous weather conditions.

For public safety, private companies in the hardest-hit regions were encouraged to let employees work from home, whilst all Dubai government employees were ordered to work remotely. Improved weather conditions are anticipated beginning Friday, with a forecast of drier weather for Saturday.
