Thick dust carried by east winds from Syria has blanketed all of Cyprus, the Meteorological Department said on Tuesday.

An official said the dust stated coming in over the eastern Mediterranean late on Monday, initially affecting eastern parts of the island, but on Tuesday morning it settled over all parts of the island.

The Department of Labor Inspection said the concentration of dust in some areas exceeded more than 80 times the acceptable concentration of 50 micrograms per cubic meter of air under European Union directives.

It said that at its peak point, dust concentration reached 3,340 micrograms per cubic meter of air, with average concentration on Tuesday morning exceeding 2,000 micrograms per cubic meter of air in several areas.

An official at the Meteorological department said the phenomenon will linger for at least 24 more hours.

Dust from the Syrian and Jordanian deserts and even from the African deserts is not a rare phenomenon for Cyprus.

But it is very rare at this time of the year and what makes it special this time is its intensity and length.

Even the Meteorological Department was taken aback, having failed to issue its customary warning when dust appearance is imminent.

An official at the department said a low pressure system in the area caused the dust to rise and be carried westwards by an air stream from the east.

He said they noticed the dust over the eastern Mediterranean shortly before it started affecting the most eastern parts of Cyprus.

Cyprus' most eastern tip is only 100 kilometers from Syria.

Visibility was cut down to a few hundred meters and police issued warnings to drivers on highways to slow down.

But flights at the two international airports of Cyprus, busy this time of the year, were not affected up to now.

The Labor Inspection Department advised people working in the open to take precautionary measures, like wearing face masks, and warned patients with respiratory problems to stay inside.

Hospitals said several people visited their emergency departments with breathing problems, but none of them was hospitalized.
