Red alert: Heavy rains hit 3 Saudi regions today
The National Center for Meteorology in Saudi Arabia issued an urgent alert, a red warning, for heavy rain expected today, Wednesday, across large parts of three major regions: Riyadh, Hail, and Qassim. This warning comes amidst severe weather fluctuations affecting the region, necessitating extreme caution from citizens and residents to avoid potential hazards associated with this exceptional weather condition, which could disrupt daily life.
Rainfall map and areas covered by the warning
The National Center for Meteorology identified the governorates and centers most affected by the current weather fluctuations, and the geographical details of the rainfall distribution are as follows:
- Riyadh Region: Includes the capital Riyadh, Al Zulfi, Al Ghat, Al Majmaah, Shaqra, Thadiq, Huraymila, Rumah, Dhurma, Marat and Al Diriyah.

Weather effects associated with a "red alert for heavy rain"
The weather conditions are not limited to rainfall alone; they are accompanied by severe weather phenomena that require full preparedness from relevant authorities and residents. These effects include:
- High-speed winds cause dust and sand to be stirred up, reducing visibility.
- There is an almost complete lack of horizontal visibility, especially on highways and in open areas.
- Heavy hail showers of varying sizes may affect vehicles and property.
- The sudden and rapid flow of torrential floods in valleys and ravines.
- Strong thunderstorms and dense fog are expected during the night and early morning hours.
General weather forecast for various regions of the Kingdom
According to the daily report from the Meteorology Center, moderate to heavy thunderstorms are expected to continue, leading to flash floods in parts of the Eastern Province, as well as the eastern parts of the Makkah and Madinah regions. Meanwhile, the sky will be partly cloudy to cloudy with a chance of thunderstorms and rain over the highlands of Al-Baha, Asir, Jazan, and Najran, with a high probability of fog forming over the highlands of these areas during the evening.
Historical background and climate changes in the Arabian Peninsula
Historically, the Arabian Peninsula experiences transitional periods between seasons characterized by the activity of low-pressure systems originating from the Red Sea or the Mediterranean basin, which converge with moist air masses from the Arabian Sea. This convergence generates strong atmospheric instability, known locally as periods of heavy rainfall, such as the "Wasam" season. However, recent climate studies indicate that the frequency of these extreme events has increased in recent years due to global climate change, resulting in heavier and more concentrated rainfall over shorter periods. This explains the frequent issuance of red alerts to protect lives and property.
Strategic importance and preventive measures locally and regionally
These warnings are of paramount importance both locally and regionally. Locally, this real-time data contributes to activating emergency plans at the General Directorate of Civil Defense and municipal and educational authorities, which may take preventative measures such as suspending in-person classes and switching to remote learning to protect students. Regionally and internationally, the Kingdom's ability to manage weather crises through advanced monitoring systems enhances the resilience of its logistical infrastructure and ensures the continued flow of vital land and air transport connecting the Kingdom with its neighbors without catastrophic disruptions, highlighting the role of modern technologies in mitigating the disasters of climate change.
