NCM Forecast: Heavy Rain, Flash Floods Possible Wednesday

The National Center for Meteorology (NCM) has issued a detailed weather forecast for Wednesday, October 7, 2026, warning of moderate to heavy rain that may lead to flash floods in parts of Jazan, Aseer, Al-Baha, and Makkah regions. The forecast, released via the Saudi Press Agency (SPA), also indicates hail and gusty, dust-stirring winds accompanying the rainfall in these areas. Light to moderate rain is expected in parts of Madinah, Hail, Tabuk, Al-Jouf, and the Northern Borders regions, while dense fog may form over parts of the Eastern Region, with thunderclouds likely over its southern parts.

Context and Background

The National Center for Meteorology is the authoritative body in the Kingdom of Saudi Arabia responsible for monitoring weather conditions and issuing timely forecasts to protect public safety and support economic activities. Its daily bulletins are disseminated through official channels, including the Saudi Press Agency, to ensure that residents, government agencies, and businesses have accurate information for planning and preparedness. The forecast for Wednesday reflects the NCM’s commitment to leveraging advanced meteorological technologies and data analysis to provide reliable early warnings, particularly for regions prone to sudden weather changes during transitional seasons.

This forecast comes as part of the Kingdom’s broader efforts to enhance disaster risk reduction and climate resilience, aligning with the objectives of Saudi Vision 2030 to improve quality of life and infrastructure safety. The NCM’s warnings are critical for local authorities, who may activate emergency response plans to mitigate the impact of flash floods and ensure the well-being of citizens and visitors alike.

Key Details

According to the NCM, the affected regions in the southwest—Jazan, Aseer, Al-Baha, and Makkah—can expect moderate to heavy rainfall, which may result in flash floods. These areas are characterized by mountainous terrain, which can exacerbate runoff and lead to rapid water accumulation. Hail and strong, dust-stirring winds are also forecast, which could reduce visibility and pose hazards to motorists and outdoor activities.

In the central and northern regions, including Madinah, Hail, Tabuk, Al-Jouf, and the Northern Borders, lighter rainfall is anticipated, which may bring relief to dry areas but could also create slippery conditions on roads. The Eastern Region, particularly its southern parts, may experience dense fog and thunderclouds, which could disrupt air and sea travel.

Marine conditions are also detailed: over the Red Sea, winds will be northwesterly to northerly at speeds of 20-40 km/h, northwesterly to westerly at 15-38 km/h, and southeasterly to easterly at 10-50 km/h. Waves will range from half a meter to over two meters, with the sea state from calm to choppy. In the Arabian Gulf, winds will be northwesterly to northerly at 10-30 km/h, and northwesterly to westerly at 10-25 km/h. Waves will be half a meter to one meter, and the sea will be calm.

Implications and Impact

The forecast has significant implications for public safety, transportation, and outdoor activities. Authorities in the affected regions are likely to issue advisories, urging residents to avoid low-lying areas and to exercise caution while driving. Flash floods can disrupt road networks, damage property, and pose risks to life, making adherence to official guidance crucial. The NCM’s early warning system enables proactive measures, such as pre-positioning emergency teams and resources, which can save lives and reduce economic losses.

For the tourism sector, particularly in regions like Aseer and Al-Baha, which are popular for their scenic landscapes, the weather may impact outdoor events and travel plans. However, the rainfall also brings environmental benefits, replenishing groundwater and supporting agricultural activities. The marine forecast is vital for fishermen, shipping companies, and coastal activities, ensuring they can plan operations safely. Overall, the NCM’s detailed bulletin demonstrates Saudi Arabia’s robust meteorological infrastructure and its dedication to safeguarding communities and fostering sustainable development.

Vision 2030 Alignment

The National Center for Meteorology’s work is integral to Saudi Vision 2030, which aims to enhance the Kingdom’s resilience to natural disasters and improve the quality of life for all. By providing accurate and timely weather forecasts, the NCM supports key sectors such as tourism, agriculture, and transportation, contributing to economic diversification and sustainable growth. Moreover, the center’s advancements in meteorological technology reflect the broader vision of transforming Saudi Arabia into a global hub for innovation and smart solutions. As the Kingdom continues to invest in climate adaptation and disaster preparedness, the NCM remains at the forefront, ensuring that both citizens and visitors can enjoy the nation’s offerings safely and confidently.
