Temperatures set to fall as first wave of Shamal is expected

Temperatures are likely to drop, especially in coastal areas, from Friday as the season's first wave of cooler Shamal (north-westerly) winds are expected to hit the UAE and other parts of the region.The development is expected to reduce the development of fog that has been severely affecting the UAE for the past week."Fog is likely to develop in some areas but its severity will go down," said forecasters.Late night and early morning fog has wreaked havoc on UAE roads with hundreds of accidents in Dubai and Sharjah, including a 36 vehicle pile-up in Dubai.The other change expected is a significant drop in temperature, particularly in coastal areas, said Adel Hassan, a meteorologist in Al Ain, adding an atmospheric low pressure area over Iran will push cooler winds into the UAE."It is a pleasant seasonal change and people will have more tolerable daytime conditions across the emirates," said Hassan.He said seasonal changes always bring some risk of ailments such as flu, coughs and allergies. It is advisable to take care of children and the elderly in such conditions, he said.The National Centre of Meteorology and Seismology (NCMS) also acknowledges the wave of cooler winds from tomorrow, saying they will be stronger over the sea. The winds are likely to generate seven- to nine-foot-high waves offshore, making the sea risky for small boats and vessels.Winds will be moderately rough in general and become even stronger in internal areas, kicking up dust and sand.The weather will be partly cloudy tomorrow in some areas.Meanwhile, forecasters expect patches of dense fog this morning. Conditions will be relatively hot during the day and mild to pleasant at night. Drivers are advised to be cautious.
