Iran: Dust storms causing disruptions in multiple regions May 17

Event

A severe dust storm is causing disruptions across many parts of Iran as of May 17. Schools, universities, and public offices are closed across Tehran due to the adverse conditions and sessions at the Iranian parliament have been suspended. The dust storm moved eastwards having impacted Syria and Iraq in recent days and some airports in western Iran saw dozens of flights canceled and delayed May 16 as the storm moved in from Iraq. The dust storm has impacted other cities including Sanandaj, Kermanshah, Ilam, Khorramshahr, Sardasht, and Hamadan and schools and offices have also been closed across Hamedan, Lorestan, Ilam, Alborz, Kermanshah, Markazi, Khuzestan, Bushehr, and Kurdistan provinces May 17. Further disruptions are possible in the coming hours and days depending on the progression of the storm. This is the third major dust storm to impact Iran since mid-April.

Transport
In addition to posing a direct health risk to those with pulmonary or respiratory issues, large storms can delay air and ground transport operations due to strong winds and low visibility. Dust storms can cause hazardous driving conditions, resulting in traffic congestion and an increased frequency of accidents.

Flight delays, diversions, and cancellations are possible at airports across affected regions during periods of severe dust storm activity. Disruptions are typically more severe during rush-hour periods. Poor local driving practices, such as not using headlights at night or failing to allow for a safe distance between vehicles, could compound weather-induced hazards.

Hazardous conditions may prompt school or business closures. Higher-than-normal employee absenteeism is likely in the event of widespread transport disruptions. Residual business and transport disruptions are possible even after weather conditions improve.

Advice

Monitor local media for updated and related weather advisories. Exercise caution while driving and allow additional time to reach destinations. Confirm flights before checking out of hotels or returning rental cars. Plan for possible delivery delays. If operating in areas affected by dust storm activity, consider remaining indoors when possible. Those who must be outdoors should use face masks and observe other precautions to avoid dust inhalation.
