A regional state of atmospheric instability includes 10 Arab countries and is accompanied by 7 weather phenomena in the coming days

Arab Weather - Weather experts at the Arab Weather Regional Center reported that the latest computer simulation results indicate that 10 Arab countries will be affected by a state of atmospheric instability from Wednesday, October 30, until Sunday, November 3, with varying intensity from day to day, and its peak will be at the end of the week and the beginning of next week. This is due to the convergence of a cold air mass in the upper layers of the atmosphere with a surface extension of the Red Sea depression, which leads to the proliferation of cumulonimbus clouds and the fall of thunderstorms in several regions.

It includes 10 countries.. and is accompanied by 7 weather phenomena in the coming days

The state of atmospheric instability includes 10 Arab countries, making it regional. The countries are the Levant, Egypt, and Libya, in addition to Saudi Arabia, Kuwait, Iraq, and Yemen. It is accompanied by weather phenomena that differ in their comprehensiveness from one region to another, as one region may be exposed to all weather phenomena, while another witnesses only two or three phenomena. The weather phenomena are:

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

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

3. Hail: Hail showers may fall in some areas, and they may be heavy and large in size.

4. Sudden strong winds: Strong winds are expected during the passage of thunderstorms, which leads to raising dust.

5. Rising water levels: The water level in the valleys is likely to rise, increasing the risk of flash floods.

6. Poor visibility: Dust caused by winds may cause poor visibility in some areas.

7. Rapid changes in the weather: Sudden changes in the weather are expected, which requires caution and attention.

Unstable weather conditions are random but dangerous and require preparation.

Experts at "Arab Weather" pointed out that the cases of atmospheric instability affecting the region are characterized by random rainfall, which means that there are likely to be large differences in the locations and intensity of rainfall within small geographical areas. This variation is a risk factor, as it leads to significant valley flow and the formation of movable torrents that move from one place to another without the need for rainfall in that area. These cases are also characterized by rapid weather changes in short periods of time.

Why are atmospheric instability dangerous in some areas?

Unstable weather conditions can become dangerous in some areas due to the formation of flash floods resulting from heavy rainfall in narrow areas and in a short period of time. This is especially true in rocky or mountainous areas, where rainwater collects from above into valleys. Previous dry seasons also increase the likelihood of floods, because the water does not find channels to absorb it into the ground, which leads to water accumulating on the surface and starting to flow quickly into valleys. Therefore, it is advisable to follow the paths of floods and stay away from valleys and low-lying areas when there is a state of unstable weather or low-pressure systems.

And God knows best.
