MUSCAT: The Sultanate of Oman is currently under the influence of a trough of upper air, bringing continuous cloud advection and widespread weather instability across most governorates. Forecasts indicate isolated rainfall of varying intensity with occasional thunderstorms, particularly over Al Wusta, Dhofar, South and North Al Sharqiyah, and parts of A’Dakhiliyah and A’Dhahirah. The situation is expected to intensify in specific regions, requiring residents and travelers to remain alert as conditions develop. These weather systems are accompanied by increased moisture flow from the Arabian Sea, creating favorable conditions for thunderstorms and localized heavy rain events.
On Tuesday, August 19, significant rainfall activity is anticipated, especially in Al Wusta and Dhofar, where rain intensity is forecast to increase compared to other areas. Isolated thunderstorms may develop, producing downdraft winds that can lead to hazardous conditions such as flying debris and unstable objects being displaced. In addition, poor horizontal visibility and blowing dust are expected in affected regions, further complicating road safety and outdoor movement. Sea conditions along the Arabian Sea coast will remain rough, with wave heights reaching up to 4 meters, posing risks to marine activities.
The weather system is projected to persist into Wednesday, August 20, bringing widespread cloud cover and intermittent thunderstorms to most governorates. Rainfall intensity is likely to increase over South and North Al Sharqiyah, Al Wusta, and Dhofar, with precipitation levels ranging between 10-30 mm, enough to cause the flow of some wadis. Strong downdraft winds between 20-45 knots (37-83 km/h) will continue to present a threat, particularly for unsecured objects and exposed structures. Maritime conditions will remain hazardous for small craft and fishing vessels, reinforcing the need for caution before engaging in any marine activity.
From Thursday through Friday, August 21-22, the unstable weather pattern is expected to sustain its impact, with chances of isolated heavy rain and thunderstorms persisting across multiple regions. Rainfall during this period could range from 15-40 mm, intensifying the likelihood of flash floods in low-lying areas and wadis. Authorities urge the public to remain vigilant, avoid crossing flooded areas, and adhere to official advisories. The Civil Aviation Authority strongly recommends checking sea conditions before sailing and following weather updates regularly. With rough seas, reduced visibility, and potential flash flooding, safety precautions are essential to minimize risks during this period of unstable weather.
