Saudi NCM Forecasts Thunderstorms, Flash Flood Risk for

The National Center for Meteorology (NCM) has issued a weather forecast warning of moderate to heavy thunderstorms that could trigger flash floods across several regions of the Kingdom of Saudi Arabia, accompanied by hail and dust-stirring winds, according to an official bulletin released through the Saudi Press Agency. The forecast, dated Wednesday, November 11, 2026, identifies parts of the Riyadh, Qassim, Eastern, Madinah, Makkah, Al-Baha, Aseer, Jazan and Najran regions as areas of particular concern, while noting that fog may form in parts of those regions and that temperatures are expected to drop across most regions of the Kingdom. The advisory reflects the NCM’s ongoing role in monitoring atmospheric conditions and delivering timely, science-based guidance to citizens and residents nationwide.

For a country as geographically diverse as Saudi Arabia, weather advisories carry practical significance far beyond the daily forecast. They inform travel planning, agricultural decisions, aviation scheduling, and public safety protocols in communities that span coastal plains, highland terrain, and desert expanses. Wednesday’s bulletin arrives as the Kingdom continues to invest heavily in meteorological infrastructure and early-warning systems, part of a broader national effort to protect lives and property while supporting the ambitions of Vision 2030. How does a single weather bulletin connect to the daily lives of millions across such a vast and varied landscape? The answer lies in the NCM’s carefully calibrated regional approach to forecasting.

Context and Background

What drives the formation of thunderstorms across the Kingdom’s central and southwestern regions at this time of year? The National Center for Meteorology, the Kingdom’s authoritative meteorological body, continuously tracks atmospheric pressure systems, moisture patterns, and temperature gradients to produce forecasts that guide public and institutional decision-making. The Wednesday advisory highlights a convergence of conditions capable of producing moderate to heavy rainfall, hail, and strong, dust-stirring winds — a combination that can rapidly alter visibility and road conditions in affected areas. The NCM’s regional breakdown allows authorities and residents to prepare according to local risk rather than relying on a single national snapshot.

The advisory specifically names nine regions where thunderstorm activity is expected. These range from the central plateau around Riyadh and Qassim to the Eastern Province’s coastal and inland zones, the western regions of Madinah and Makkah, and the southwestern highlands of Al-Baha, Aseer, Jazan, and Najran. Each of these areas presents distinct topographical features — from steep mountain slopes that channel runoff quickly to expansive desert plains where dust can be lifted with little warning. The NCM’s forecast accounts for these differences, offering targeted guidance that supports safer outcomes for communities, travelers, and emergency services alike.

Fog formation is another key element of the bulletin. In parts of the affected regions, reduced visibility from fog can pose hazards for motorists, particularly during early morning hours. Combined with falling temperatures across most of the Kingdom, the forecast signals a shift in weather patterns that residents should factor into their plans. The NCM’s practice of issuing detailed, region-specific advisories underscores its commitment to transparency and public safety — a commitment that has grown more sophisticated as the Kingdom modernizes its meteorological capabilities.

Key Details of the Forecast

What should residents and travelers take away from the specific elements of the bulletin? The NCM’s forecast identifies moderate to heavy thunderstorms as the primary weather event, with the potential to cause flash floods in the affected regions. Flash flooding remains one of the most serious weather-related risks in arid environments, where dry ground can absorb little rainfall and water may accumulate swiftly in valleys and low-lying areas. The possibility of hail adds a further dimension, as hailstorms can damage vehicles, crops, and infrastructure. Dust-stirring winds, meanwhile, can reduce visibility and affect air quality, making caution essential for those on the road or working outdoors.

The bulletin also provides detailed marine forecasts for the Kingdom’s two major bodies of water. Over the Red Sea, winds will be northwesterly to northerly at speeds of 20–42 km/h in the northern part, northwesterly to northerly at speeds of 18–40 km/h in the central part, and southeasterly to northeasterly at speeds of 12–32 km/h in the southern part. In the Arabian Gulf, winds will be northwesterly to northerly at speeds of 20–45 km/h in the northern part and northwesterly to westerly at speeds of 18–45 km/h in the southern part. These figures are vital for fishermen, shipping operators, and recreational mariners who depend on accurate conditions before setting out.

Why does marine forecasting matter so much to the Kingdom? Saudi Arabia’s coastlines support a wide range of economic and recreational activities, from commercial fishing and port operations to tourism along the Red Sea. Accurate wind forecasting helps safeguard these activities and protects lives at sea. The NCM’s inclusion of detailed wind speed ranges by coastal segment demonstrates the precision that modern Saudi meteorology brings to public service, allowing mariners to make informed decisions well in advance.

International and Regional Impact

How do weather systems in Saudi Arabia ripple outward to affect the wider region? The Kingdom occupies a strategic position at the crossroads of the Arabian Peninsula, and its weather patterns often influence — and are influenced by — conditions across neighboring countries. The thunderstorm activity forecast for the southwestern regions, including Jazan and Najran near the border with Yemen, reflects broader atmospheric dynamics that can extend beyond national boundaries. Regional cooperation on meteorological data sharing, in which Saudi Arabia actively participates, helps improve forecast accuracy across the Gulf and the broader Middle East.

The marine forecasts carry regional weight as well. The Red Sea and the Arabian Gulf are among the world’s most important maritime corridors, carrying a substantial share of global trade and energy shipments. Wind advisories issued by the NCM contribute to the safety of commercial navigation in these waters, supporting the stability of supply chains that connect Asia, Europe, and the Middle East. In this sense, a routine weather bulletin serves not only national but international interests, reinforcing the Kingdom’s role as a responsible steward of regional safety and commerce.

The advisory also matters for the millions of pilgrims and visitors who travel to the Kingdom’s holy sites. Weather conditions around Makkah and Madinah are monitored with particular care, and the NCM’s forecasts help authorities and visitors alike plan for rain, fog, and temperature changes. This attention to the wellbeing of guests reflects the Kingdom’s longstanding commitment to hospitality and to the safe conduct of religious observances throughout the year.

Economic and Strategic Significance

What does a reliable weather service mean for a modernizing economy? Saudi Arabia’s economic transformation under Vision 2030 depends in part on resilient infrastructure and informed planning across sectors. Agriculture in regions such as Qassim and Aseer benefits from early warning of rainfall and hail, allowing farmers to protect crops and manage irrigation. The energy sector relies on accurate marine and coastal forecasts to support offshore operations. Transportation networks, from highways to airports, adjust schedules and safety protocols based on NCM guidance, reducing disruptions and protecting travelers.

Strategic investments in meteorological technology amplify these benefits. The NCM’s ability to deliver granular, region-by-region forecasts reflects decades of development and a forward-looking approach to environmental monitoring. As the Kingdom expands its capabilities in satellite observation, radar networks, and data analytics, the quality and timeliness of public weather information continue to improve. This progress supports the broader goal of building a safe, resilient, and diversified economy that can respond effectively to natural conditions while maintaining the confidence of investors, residents, and visitors.

Could better forecasting also become a foundation for regional leadership in environmental science? Saudi Arabia’s growing expertise in meteorology positions it to contribute meaningfully to international climate and weather research. By investing in early-warning systems and data-sharing partnerships, the Kingdom strengthens its standing as a capable and responsible actor in global environmental governance — an objective that aligns closely with the forward-looking spirit of Vision 2030.

Vision 2030 Alignment

How does a weather advisory connect to the ambitious goals of Vision 2030? At its core, Vision 2030 seeks to enhance the quality of life for all who live in and visit the Kingdom, build a resilient and diversified economy, and position Saudi Arabia as a global leader across a range of fields. Reliable meteorological services contribute directly to each of these aims. They protect communities from natural hazards, support economic activity in sectors from agriculture to tourism, and demonstrate the Kingdom’s commitment to using science and technology for public good. The NCM’s precise, timely bulletins are a practical expression of that commitment.

Wednesday’s forecast — with its warnings of thunderstorms, flash floods, hail, dust, fog, and shifting temperatures — serves as a reminder that preparedness is a shared responsibility. Residents are encouraged to follow official NCM advisories, take appropriate precautions in affected regions, and stay informed through trusted Saudi channels. As the Kingdom continues its journey toward a more prosperous and secure future, the quiet, consistent work of its meteorological institutions stands as one of the many pillars supporting that vision. In a land of diverse landscapes and changing skies, accurate forecasting is not merely a public service — it is an investment in safety, prosperity, and national progress.
