Humidity to peak this morning

CHANCE OF MIST AND FOG ALONG WESTERN COASTAL AREAS, FORECASTER SAYS

Chance of mist and fog formation along the western coastal areas of the UAE

Humid early mornings will continue in the UAE for the second straight day today, although Dubai and the northern emirates will be spared.

Forecasters at the National Centre of Meteorology and Seismology said relative humidity will shoot up, reaching up to 100 per cent from 3am today along the western coast.

“Relative humidity will increase from Sunday night to Monday early morning with a chance of mist and fog formation along the western coastal areas of the UAE,” a forecaster said.

Humidity levels were also high yesterday morning, resulting in foggy conditions in parts of the country. Dense fog caused visibility to deteriorate to 50 metres in Liwa, Madinat Zayed, and Sweihan between 3am and 6am yesterday. Other areas affected by the fog were Dubai, Sharjah, and neighbouring areas extending to Ras Al Khaimah.

“The type of fog we are experiencing now is called radiation fog which is normal at this time of the year. The conditions are perfect for fog and mist formation: gentle winds, increasing humidity, clear skies, and rapidly decreasing temperatures,” the forecaster said.

Radiation fog is common during fall and winter when the land is cooling down overnight and, in turn, cools the air close to its surface. This air then becomes saturated with moisture, resulting in condensation and fog.

But radiation fog doesn’t last long. The moisture usually dissipates as the ground becomes warm after sunrise. Yesterday, foggy conditions were experienced from 1am to 3am in some areas, and from 3am to 6am in other areas.

The weather will continue to be hot during the day with mostly sunny conditions and temperatures ranging from 32 degrees Celsius to 44C in Dubai, Abu Dhabi, and Sharjah.

Al Ain with have partially cloudy skies with average temperatures of 31C to 45C and Fujairah between 30C and 39C.
