In March 2009, one of the worst sandstorms hit Riyadh, disrupting road traffic, forcing schools and offices to shut down and provoking an outbreak of respiratory problems across the city.
Visibility plunged to zero and flights were cancelled. Incoming planes were diverted to nearby cities. The clear blue sky suddenly turned into orange-brown.
Warning from the Presidency of Meteorology and Environment (PME) appeared on Saudi Press Agency as “low visibility due to the dust storm, especially in the Central and Eastern regions, accompanied by a decrease in temperature during the night.”
