During the summer season, strong north-westerly winds blow from Saudi Arabia due to a low pressure area develop over Dubai. These winds, also called Shamal (north) in Arabic, become unpredictable and gusty on reaching Dubai. Shamal reduces visibility by boosting up the desert sand and the sandstorms may last for several days. Some notable sandstorms that happened in Dubai during the last few years are on January 28, 2011, formed a sandstorm which hit Dubai for a short time, on February 26, 2012, formed strong sandstorm which beated Dubai and other parts of the country and currently on April 2, 2015 shaped a very strong sandstorm that hit Dubai and other parts of the country.
