A powerful storm with strong winds and heavy rains is affecting Western Europe, and some of its effects are extending to the Maghreb

Arab Weather - The latest satellite images and remote sensing systems at the Arab Weather Regional Center monitor the development of a rainstorm over the waters of the northwest Atlantic Ocean off the coast of Portugal, with very low atmospheric pressure values reaching 986 millibars, causing strong winds with an average of 100 km/h and gusts exceeding that, with the presence of dense bands of thick cumulonimbus clouds laden with large amounts of rain surrounding the center of the storm.

Storm affects Portugal and France (heavy rain and strong winds).

According to the latest outputs from the so-called numerical models, and based on satellite image data, the storm is expected to have a strong impact on Portugal and Spain this evening and throughout tomorrow, Saturday, as large amounts of cumulus clouds will rush in and unstable weather conditions will prevail, causing heavy to very heavy rains that are characterized by being continuous, and sometimes accompanied by strong thunderstorms in several areas, including the capital, Madrid, with heavy falling of hail of various sizes and sometimes large.

The storm is expected to cause a huge rainfall of between 150-250 mm of rain, which means about 250 liters of water per square meter, causing torrents and floods and a significant rise in water levels on the roads, including the capital, Madrid.

The Siberian high is rebuilding itself, does this herald the arrival of cold waves?

The storm is weakening and affecting the Maghreb and Algeria indirectly.

The storm is expected to move south on Saturday and Sunday, but it will gradually weaken and the atmospheric pressure will rise at its center and indirectly affect the Maghreb, and a state of complex atmospheric instability will form over (Morocco and eastern Algeria). As a result, thunderclouds will form and grow to high levels in the atmosphere.

Severe cold waves accompanied by snow and negative temperatures will affect northwestern Europe and North America in the coming days

It is accompanied by severe weather phenomena such as (heavy rain, thunderstorms and lightning, strong hailstorms with large hailstones, and strong downward winds). The terrain and topography of the land contribute to the process of lifting the air, especially the Atlas Mountains and neighboring areas. Mountain valleys and low-lying areas are susceptible to the sudden formation of torrential floods, in addition to the high risk of flooding in several areas due to the large amounts of rain expected in some areas.

God knows best.
