Heavy rains in the southern highlands extending to Riyadh and the Eastern Province

Weather forecast: Heavy rains and unstable weather conditions hit regions of the Kingdom

Saudi Arabia is currently experiencing significant weather fluctuations, with authorities warning of heavy rainfall accompanied by thunderstorms in the southwestern highlands. This weather system is also expected to affect large parts of the Riyadh and Eastern Provinces. These developments are part of a series of weather changes being closely monitored by national meteorological centers, which continue to urge citizens and residents to exercise extreme caution and stay away from flood-prone areas.

The geographical and historical context of the climate of the southwestern highlands

The southwestern highlands of the Kingdom, encompassing the regions of Jazan, Asir, and Al-Baha, extending to the highlands of Makkah, are characterized by a unique geographical and climatic landscape. Historically, these areas have received the most rainfall in the Arabian Peninsula, thanks to their high mountainous terrain, which plays a crucial role in the formation of cumulonimbus clouds. These highlands are influenced by monsoon winds that bring moisture from the Red Sea and the Arabian Sea, resulting in both summer and winter rainfall. Frequently, atmospheric pressure systems form, pushing these rain clouds inland, which explains the current weather system's extension to include the capital, Riyadh, and the Eastern Province.

Details of the weather situation and its direct effects

The expected heavy rainfall will be accompanied by a range of severe weather phenomena, most notably hail and strong surface winds that may stir up dust and sand, leading to reduced horizontal visibility on some open and express roads. This heavy rainfall also increases the likelihood of flash floods in valleys and ravines, requiring special attention from motorists and residents of low-lying areas. In Riyadh and the Eastern Province, this rain is expected to moderate temperatures and contribute to the formation of water pools in some vital locations.

Importance and expected impact (locally and regionally)

Locally, these rains have a dual impact. On the one hand, government agencies such as the General Directorate of Civil Defense and traffic departments are mobilizing their personnel to ensure the safety of lives and property, and in-person classes may be suspended in some governorates as a precautionary measure to protect students. On the other hand, these rainfalls are of paramount importance to the agricultural sector, contributing to the irrigation of farms, enhancing vegetation cover, raising groundwater levels, and replenishing water reserves in strategic dams across the Kingdom.

Regionally, these weather fluctuations occur within the context of broader climate changes affecting the Middle East and the Arabian Peninsula. Meteorologists have observed an increase in the frequency and intensity of extreme rainfall events in recent years, reflecting shifts in global weather patterns. This change necessitates strengthening infrastructure and developing early warning systems to address weather phenomena more effectively, a goal that Saudi Arabia is pursuing as part of its future vision to ensure environmental sustainability and protect society from natural disasters.
