Dubai: Get your handkerchiefs or face covers ready, especially in the morning on Tuesday and Wednesday, as winds may kick up more dust in exposed areas and cause poor visibility.
“It will continue to be hazy over the next two days because of the southeasterly to northwesterly flow, freshening at times, becoming strong during the beginning of daytime,” a forecaster from the National Centre of Meteorology and Seismology (NCMS) told Gulf News.
The hazy condition is due to the low pressure over the Empty Quarter or Rub Al Khali, the world’s largest continuous sand desert in the south of the UAE, and a high pressure in southeast Iran. This difference in pressure creates a force called pressure gradient, which moves air from higher pressure toward areas with lower pressure.
In the UAE’s case, winds from southeast Iran flow towards the UAE in a circular pattern over the Arabian Gulf, resulting in rough seas and winds that kick up dust. The higher the gradient, the stronger the winds become.
The forecaster said NCMS monitors models of pressure systems every 12 hours and, based on current reports at the bureau, there will not be much of a change for the next two days.
The Arabian Gulf and Oman Sea will be rough over the next two days with wind speeds reaching 25 knots, passing over a maximum of 50 knots at times. Waves offshore could reach up to 9 feet over the northern part of the Gulf.
Despite the freshening winds, temperatures will continue to be high to very high with the mercury reaching the high 40s.
“The heat coming from the desert (Rub Al Khali) is influencing the heat we’re feeling now. Coastal areas will have 40C to 47C while interior areas may have 47C to 49C, and some areas may register 50C. But this may happen in one weather station in the middle of the desert that’s not inhabited.”
Fujairah will have favourable conditions of between 38C and 39C. Forecasters are also expecting rain in this part of the country on Monday and Tuesday.
