Dust storms originating from Iraq are forecast to impact air quality across multiple Middle Eastern countries including Iran, Syria and Kuwait over the next five days, with Iran's Meteorological Organisation warning of severe conditions, Tasnim News Agency reported on July 4.

In what has become a common warning during summer heat, Iran's meteorological officials forecast air quality deterioration across most regions, particularly in northeastern, eastern and central areas, due to strong winds and dust storms originating in Iraq and Syria until July 7. 

Sadeq Ziaeian, Director of Iran's National Weather Hazards Forecasting and Crisis Management Centre, said strong winds and dust storms will occur at certain hours, significantly affecting air quality across the region.

Iraqi meteorological authorities reported that dust conditions will continue affecting the country through July 8, with temperatures reaching 44°C in Basra and Maysan provinces. The dust is expected to spread westward into Syria and southward into Kuwait.

Reports from Iraq and Iran report show “hazardous” air quality indices of above the highest recording available for PM2.5 at 500. Other regional countries, including the United Arab Emirates (UAE) reported “unhealthy” air quality in Abu Dhabi.

Syria's meteorological department has issued advisories for eastern provinces bordering Iraq, warning residents of reduced visibility and health risks from airborne particles.

Kuwait's environmental monitoring stations have recorded increased particulate matter levels, with authorities advising residents to limit outdoor activities and wear protective masks.

In Iran, the southwestern city of Ahvaz is forecast to experience the worst air pollution, with temperatures reaching 44°C on July 5 and 43°C on July 6, combined with heavy dust concentrations. The city frequently ranks among the world's most polluted urban areas during summer dust storm seasons.

Ziaeian said convective cloud development and thunderstorms are forecast for northern Iranian provinces, whilst the Caspian Sea, Strait of Hormuz and Sea of Oman will experience rough conditions.

Regional aviation authorities have issued flight advisories due to reduced visibility, with several airports across Iraq, western Iran and eastern Syria implementing enhanced monitoring procedures. 

The warnings come as Tehran air authorities have reopened the city's biggest airports following the 12-day war with Israel. FlyDubai flight FZ1930 from the UAE to Tehran (IKA) marked the resumption of international flights after the suspension period.
