Heavy Fog Cuts Visibility Across UAE Roads Through Tuesday Morning—Speed Limits Drop to 80 km/h

The United Arab Emirates National Centre of Meteorology has confirmed heavy fog blanketing coastal and inland zones tonight through Tuesday morning, with visibility expected to drop dangerously low. Abu Dhabi authorities have reduced speed limits to 80 km/h on affected roads, with enforcement already active.

Immediate Alert: Tonight Through Tuesday Morning

The National Centre of Meteorology issued its alert from 10 PM Monday, February 23 through 10 AM Tuesday, February 24. The warning covers coastal strips, inland areas, and island zones—regions currently experiencing significantly reduced visibility.

Real-time traffic data confirms multiple incidents already reported on high-volume arteries including Ras Al Khor Road, Beirut Street, Sheikh Mohammed Bin Zayed Road, and Al Ittihad Street. Commuters in Sharjah and Dubai are reporting extended travel times on normally routine drives.

The Abu Dhabi Police have imposed 80 km/h speed caps on Sheikh Khalifa bin Zayed International Road, Abu Dhabi-Al Ain Road, and Sheikh Mohammed bin Rashid Road. Enforcement is immediate, with traffic cameras calibrated to ticket drivers exceeding the reduced threshold.

Why This Matters for Your Commute

• Travel times doubling: Major routes in Abu Dhabi and Dubai are experiencing hour-long delays during peak fog hours.

• Speed enforcement active: Fines for exceeding 80 km/h limits are already in effect across monitored corridors.

• Zero visibility reported: Some drivers are reporting near-zero visibility on key corridors, increasing collision risk significantly.

What Drivers Should Know Right Now

Check the forecast before you leave. The NCM issues real-time alerts through its app and website. If visibility is severely compromised, delay the trip if possible.

Drop your speed and widen your following distance. Road Safety UAE recommends at least a five-second gap between vehicles in fog, compared to two seconds in clear conditions. Abu Dhabi's enforced 80 km/h limit is not a suggestion—cameras are active.

Use low-beam headlights and front/rear fog lights only when visibility falls below 100 meters. High beams reflect off the fog and worsen your field of view. Switch fog lights off once the mist clears to avoid dazzling other drivers.

Avoid lane changes and overtaking. Stick to your lane using reflective road studs and lane markers as guides. Sudden steering, acceleration, or braking increases the risk of rear-end collisions.

If visibility drops to zero, pull off safely. Service roads, parking lots, or petrol stations are preferable to highway shoulders. Activate hazard lights only when stationary, not while moving.

February's Fog Pattern

This alert marks one of several significant fog events across February. On February 10 and 11, heavy blankets of mist caused flight cancellations and doubled travel times for thousands. A week later, on February 17, visibility plunged across western regions, prompting the NCM to issue red-level warnings. The February 22-23 wave brought another round of alerts, with humidity spiking overnight.

The cumulative effect has tested the UAE's transport infrastructure and commuter schedules throughout the month.

Why the UAE Experiences Winter Fog

Despite its desert geography, the Emirates logs upward of 50 foggy nights annually, with the season running from September through March and peaking in December and January.

The dominant mechanism is radiation fog, which accounts for roughly 95% of events. During winter, sea breezes carry moist air from the Arabian Gulf inland by day. After sunset, the desert surface cools rapidly, and the trapped water vapor condenses into thick ground-level clouds. This inland belt—typically 20 to 100 kilometers from the coast—sees the highest frequency of low-visibility events.

Fog typically forms between 7 PM and 11 PM, intensifies between 3 AM and 7 AM, and dissipates with the rising sun by 8 or 9 AM. Abu Dhabi International Airport experiences more fog-related disruptions than Dubai or Al Ain due to its position within this inland zone.

Impact on Airports and Ports

While road transport bears the immediate burden, fog also complicates operations at Dubai International (DXB) and Abu Dhabi International (AUH). Modern navigation systems permit low-visibility landings, but these protocols slow arrivals and departures. Arriving aircraft enter extended holding patterns as visibility fluctuates around minimums, and ground crews contend with restricted apron visibility, lengthening turnaround times.

Cargo operations face the same air traffic control constraints, and harbor masters at coastal ports reassess vessel traffic flows when thick mist settles over approaches and channels. Piloted entries and tug operations become more complex, resulting in delayed berthing windows.

Bottom Line for Residents

For anyone with a morning commute or time-sensitive travel tonight through Tuesday morning, allow extra time, verify current conditions through official NCM alerts, keep your fog lights functional, and maintain reduced speeds on affected corridors. Monitor official channels before heading out, and remember that safety margins matter more than schedule adherence in low-visibility conditions.
