This alert specifically targets the Makkah region, including the coastal governorates of Jeddah and Rabigh. Citizens are urged to exercise extreme caution and strictly follow all safety guidelines provided by the relevant authorities. ## Meteorological Forecast Data According to the National Center for Meteorology, the weather system is expected to bring thunderstorms accompanied by hail and active winds. These winds are likely to stir up dust and sand across ten different regions of the Kingdom. Additionally, there is a significant probability of fog formation in several affected areas. ## Broad Geographical Impact The unstable weather conditions are not limited to Makkah. The forecast indicates that Jazan, Asir, Al-Baha, Madinah, and Hail will also experience these patterns. Furthermore, the Northern Borders, Al-Jouf, Tabuk, and northern parts of the Eastern Province are included in the meteorological report, highlighting a widespread atmospheric disturbance across the country. ## Red Sea Wind Dynamics Surface winds in the Red Sea are expected to shift based on the specific sector. In the northern and southern parts, speeds will range between 15 and 40 kilometers per hour. However, these speeds can exceed 50 kilometers per hour during the formation of rain-bearing thunderclouds, creating hazardous conditions for maritime activities. ## Central Red Sea Patterns In the central part of the Red Sea, wind directions are predicted to transition from northeasterly to southeasterly. After midday, these are expected to shift toward southwesterly and southeasterly directions. While base speeds remain between 10 and 32 kilometers per hour, they may spike significantly during periods of active thunderstorm development. ## Maritime Wave Conditions Wave heights across the Red Sea are generally expected to range from half a meter to one and a half meters. During the formation of rain-bearing thunderclouds, wave heights may exceed two meters. Consequently, the sea state will transition from light to moderate, becoming rough during periods of intense weather activity. ## Arabian Gulf Forecast The Arabian Gulf is also subject to weather fluctuations. In the northern sector, surface winds will blow from the southeast to the east at speeds of 15 to 40 kilometers per hour. Similar to the Red Sea, these speeds are expected to exceed 50 kilometers per hour during active thunderstorm events. ## Safety and Preparedness Measures The Civil Defense emphasizes that public safety remains the primary priority during these weather events. Residents should monitor official updates from the National Center for Meteorology regularly. By adhering to instructions and avoiding areas prone to flooding or low visibility, the public can mitigate risks associated with these sudden meteorological shifts. ## Sources covering this story - https://www.okaz.com.sa/local/na/2274226 — --- _Summary written by Brifing from the original reporting.
