Heavy rains and hailstorms are expected to hit eight Arab countries starting Friday.

Arab Weather - The latest outputs of numerical models and computer simulations indicate the continuation of a state of atmospheric instability affecting large parts of the Arab world, with expectations of weather fluctuations including chances of thunderstorms, starting from Friday, which may be accompanied by the flow of valleys and torrents in some areas.

Continued instability in the Maghreb region

Forecasts show that the Maghreb countries will be affected by a state of atmospheric instability during the weekend, with thunderstorms increasing at intervals, and chances of rain include areas of northern Algeria and Tunisia, in addition to parts of the Maghreb highlands.

These rains are expected to be thundery at times and may be heavy at certain times, which increases the likelihood of flash floods and overflowing valleys, in addition to downdrafts and hail in some areas.

There is a chance of rain in Libya and northern Egypt at the beginning of next week.

Forecasts indicate that areas of northern Libya and northern Egypt will be affected by an air mass with cooler temperatures and higher humidity, especially on Sunday, resulting in the appearance of low clouds and a chance of rain in some areas, which is unusual for this time of year.

Influences extending to the Levant

The effects of this air mass are also expected to extend to the eastern Mediterranean basin, including parts of the Levant, including Syria, Lebanon and Palestine, with chances of rain showers, especially in coastal areas.

The forecast indicates that the chances will be concentrated next Monday in a manner that is relatively unusual for this time of year, with the possibility of local thunderstorms at times.

Thunderstorms in southern Arabia

In another context, forecasts indicate the continuation of seasonal thunderstorm activity over the mountainous highlands in southwestern Saudi Arabia and Yemen, where the chances of thunderstorms that may sometimes be heavy, especially over the highlands, remain.

The forecast also includes parts of Oman and eastern UAE, with the possibility of local thunderstorms, which may be accompanied by:

Rain of varying intensity

Downdraft activity

Opportunities for valleys and torrents to flow

Hail fell

And God knows best.
