Arab Weather - With the onset of autumn and the approach of the autumnal equinox, forecasts indicate a heat dome will form over several Arab countries, creating hotter-than-usual conditions for this time of year.

Heat dome affects Maghreb countries

Latest weather forecasts indicate that the Maghreb countries will continue to be affected by a heat dome over the weekend. Temperatures are expected to reach the mid-forties Celsius in some parts of Morocco, while exceeding 40°C in southern Algeria. This reflects extremely hot and unusual conditions as the autumnal equinox approaches.

 

Meanwhile, forecasts show another heat dome developing over eastern Saudi Arabia, southern Egypt, and northern Sudan, coinciding with the autumnal equinox. This will bring remarkably hot weather, with temperatures reaching the mid-forties Celsius in some areas of the Tihama region of Saudi Arabia, further intensifying the heat in those regions.

 

What is a heat dome?

A heat dome is a weather phenomenon that forms when a high-pressure area dominates a large area for several consecutive days, acting as a blanket that prevents hot air from escaping upward. This traps heat in the layers of the atmosphere near the surface, significantly increasing temperatures and increasing the heat and intensity of the weather over time.

According to forecasts, the heat dome is expected to continue to affect the Maghreb countries and parts of the Arabian Peninsula for several days, meaning unusually hot weather for early autumn. Residents are urged to avoid direct sunlight, especially during the midday hours.

 

And God knows best.
