Weather warnings from the National Center for Meteorology
The National Center for Meteorology in Saudi Arabia issued a series of advanced weather alerts for several regions today. The center warned of moderate to heavy rainfall in the Al-Baha region, accompanied by strong winds and thunderstorms, while the Hail region is experiencing active winds stirring up dust and sand, which may develop into dust storms.
Weather details for the Al-Baha region
According to the center's warnings, the Al-Baha region is expected to experience unstable weather conditions until 10:00 PM. These conditions will include moderate rainfall accompanied by strong winds that may reduce horizontal visibility to near zero. The center also warned of the possibility of flash floods in valleys and ravines, hail, and thunderstorms. The affected areas include Al-Baha city and the governorates of Al-Qura, Al-Mandaq, Baljurashi, Bani Hassan, and Al-Aqiq, as well as surrounding areas.
Winds and dust storms in the Hail region
In the Hail region, the center warned of strong surface winds stirring up dust and sand, leading to a significant decrease in horizontal visibility, potentially dropping below one kilometer. This includes highways and open areas, posing a risk to traffic. The center indicated that this weather condition is expected to persist until 4:00 PM today.
The climatic context of weather phenomena in the Kingdom
These warnings come in the context of the diverse climate that characterizes Saudi Arabia. While a dry desert climate prevails across most of the country, the southwestern highlands, including the Al-Baha region, enjoy a relatively temperate and more humid climate, making them susceptible to seasonal rainfall, particularly during the spring and summer months. This rainfall is known for its sudden and heavy downpours, which can raise water levels in valleys and cause flash floods. Dust storms, such as those in Hail, are a common weather phenomenon, typically occurring during the transitional periods between seasons. These storms are caused by the passage of low-pressure systems that generate strong winds carrying dust and sand from the vast desert regions.
Importance and expected effects
Locally, these weather phenomena have varying impacts. In Al-Baha, while rain poses a risk of flash floods, it is a vital source for replenishing groundwater reservoirs and supporting the region's renowned agriculture. However, this situation necessitates a swift response from relevant authorities, such as the Civil Defense, to advise residents and visitors to stay away from floodplains and valleys. In Hail, the direct impact of dust storms is the disruption of land and sometimes air transport, in addition to negative health effects on those with respiratory illnesses. Authorities consistently urge drivers to exercise extreme caution during periods of reduced visibility and to adhere to safety instructions issued by official bodies.
