Wednesday will be another windy and dusty day in the <a href="https://www.thenationalnews.com/tags/uae/" target="_blank">Emirates</a>, with rough seas. Temperatures will increase slightly, compared to recent days, reaching 35°C in <a href="https://www.thenationalnews.com/tags/abu-dhabi/">Abu Dhabi</a> and <a href="https://www.thenationalnews.com/tags/dubai/">Dubai</a>. It will be hotter in the south, reaching as high as 43°C close to the border with Saudi Arabia. Moderate to fresh winds will strengthen at times, blowing dust and sand, especially in the east. Both the Arabian Gulf and Oman Sea will be rough at times. <a href="https://www.thenationalnews.com/tags/weather/" target="_blank">The weather</a> is expected to be similar for the remainder of the week. Periods of dusty weather are not unusual at this time of year, when rising temperatures cause strong winds that whip up dust and sand. Sandstorms typically contain silica crystals, as well as viruses, bacteria, dust mites, fungi and even plants. They have been blamed for <a href="https://www.thenationalnews.com/uae/2022/05/09/what-causes-the-uaes-sandstorms-and-how-common-are-they/" target="_blank">spreading meningitis spores across Africa</a>. The storms can also transmit viruses such as influenza, scientists have said. Experts have said sand particles can be inhaled, but are usually too large to be deposited in the lungs, so they generally become trapped in the upper airway. As a result, upper airway and mucus membrane irritation is the most common health problem. People who have allergies or asthma experience the most difficulties.
