Horizontal visibility drops below one kilometer in western regions as the National Center of Meteorology warns of recurring night and early morning fog through Tuesday, driven by radiative cooling and high humidity across the United Arab Emirates.
Meteorologists Issue Fog Warnings Through Tuesday
Drivers across the United Arab Emirates face worsening visibility as the National Center of Meteorology warns of fog forming from midnight through early morning. The weather agency reports that these low-visibility conditions will persist through Tuesday, affecting coastal and interior areas, particularly in the western regions where horizontal visibility can drop below one kilometer.
As evening temperatures fall, moist air near the ground cools and water vapor condenses into suspended droplets. This radiative fog typically forms during the night and early dawn hours, gradually dissipating as morning temperatures rise or winds pick up.

Astronomy Experts Identify Atmospheric Drivers
Ibrahim Al Jarwan, chairman of the Emirates Astronomy Society and a member of the Arab Union for Astronomy and Space Sciences, notes that this type of weather is characteristic of the autumn transition. Meteorologists point to three primary conditions that create this radiative fog: high humidity, clear skies, and calm winds.
According to Al Jarwan, October, November, and March experience the highest frequency of fog formation, each averaging more than twelve days of low-visibility events during the season.

Light Winds and Clear Skies Prevail Across the Country
Winds remain light to moderate, blowing from the southeast to the northwest at speeds between 10 and 20 kilometers per hour, with occasional gusts reaching 30 kilometers per hour. Both the Arabian Gulf and the Sea of Oman experience light wave conditions, while daily forecasts indicate a mix of clear to partly cloudy skies across the country, with clouds developing eastward and southward by the afternoon.

Authorities Issue Commuter Safety Advisories
Authorities urge motorists to exercise caution on the roads, monitor weather updates for fog timing, and reduce vehicle speeds to maintain safety margins during morning commutes. October, November, and March each average more than twelve days of low-visibility events during the season.
