A widespread rainy spell affecting several Arab countries, accompanied by 5 significant weather phenomena.

Arab Weather - Weather experts at the Arab Weather Regional Center reported that the latest outputs from computer simulations indicate that 10 Arab countries will be affected by a state of atmospheric instability from Saturday, December 6, until Monday, December 8, with varying intensity from day to day and from country to country. This is due to the meeting of a cold air mass in the upper layers of the atmosphere with a surface extension of the Red Sea trough, which leads to the proliferation of cumulonimbus clouds and the rainfall of thundery showers over several regions.

It includes 10 countries and is accompanied by 5 weather phenomena in the coming days.

The unstable weather conditions affect 10 Arab countries, making it a regional phenomenon. These countries include the Levant, Egypt, Saudi Arabia, Iraq, and possibly Kuwait. The weather phenomena vary in their intensity from one area to another; some areas may experience all of these phenomena, while others may only experience two or three. These weather phenomena include:

Rain showers: Thunderstorms with rain showers are expected, with the possibility of heavy rainfall in some areas.

Thunderstorms: The rain will be accompanied by thunderstorms and lightning.

Hailfall: Hail showers may occur in some areas, and may be heavy and large in size.

Sudden strong winds : Strong winds are expected during the passage of thunderstorms, which will stir up dust.

Reduced visibility : Dust caused by wind may reduce visibility in some areas.

Unstable weather conditions are random but dangerous and require preparedness.

Experts at Arab Weather noted that the unstable weather patterns affecting the region are characterized by random rainfall, meaning there are likely to be significant variations in the location and intensity of precipitation within small geographical areas. This variability is a risk factor, as it can lead to significant flash flooding and the formation of torrents that travel from place to place without any prior rainfall in the area. These weather patterns are also characterized by rapid changes in weather over short periods.

Why are atmospheric instability conditions dangerous in some areas?

Unstable weather conditions can become dangerous in some areas due to the formation of flash floods resulting from heavy rainfall concentrated in small areas over a short period. This is especially true in rocky or mountainous regions, where rainwater collects from higher elevations and flows down into valleys. Previous dry seasons also increase the likelihood of flash floods, as the water lacks underground drainage channels, leading to surface accumulation and rapid flow down valleys. Therefore, it is advisable to monitor flood channels and avoid valleys and low-lying areas during periods of unstable weather or low-pressure systems.

And God knows best.
