Al Ain: Foggy conditions across the UAE are likely to persist until the weekend, with forecasters expecting an increase in humidity and a gradual fall in night-time temperatures.

The fog, especially late at night and early in the morning, means drivers have to be extra careful and forecasters have advised them to follow traffic police advice to avoid accidents.

Many areas in Dubai, Sharjah, and desert areas, including parts of Al Ain, were Monday enveloped in dense fog that reduced visibility to less than 500 metres.

Ahmad Sajwani, an Emirati meteorologist, said October is known for its foggy conditions due to contrasting day and night temperatures, the high level of humidity, clear skies, and non-windy conditions. Clear skies at night help moist air cool down and reach condensation point rapidly.

‘Visibility problem'

"Fog can be considered as ground-level cloud that can cause a severe visibility problem in the affected areas," he said. Sajwani expects windy conditions by the end of this week that will reduce the fog.

The weather has returned to normal after a period of rain last week. Milder weather is expected over the Arabian Peninsula in general. "A stagnant high pressure is expected to start building up that might not fade away until at least October 20," he said.

The National Centre of Meteorology and Seismology (NCMS) said it will be relatively hot today, becoming partly cloudy at times over some eastern areas. It will be mild and humid tonight.

Winds will be light to moderately rough but could gain speed by the afternoon. There is a chance of fog in coastal and internal areas at night and early this morning. The maximum temperature is expected to rise to 41 degrees Celsius and the minimum temperature is likely to drop to 24 degrees. Read more weather updates
