Saudi Arabia is preparing for the onset of meteorological winter, beginning December 1st, with a forecast of gradually decreasing temperatures and increased chances of rainfall across several regions. Hussein Al-Qahtani, spokesperson for the National Center for Meteorology (NCM), announced the seasonal shift and predicted the arrival of a significant rainy spell next Sunday. The anticipated weather changes follow a period of relatively stable conditions and will impact areas previously affected by recent precipitation.
The cooling trend and potential for rainfall are expected to be felt throughout the Kingdom, but particularly in the Madinah and Hail regions, the highlands of Makkah, and portions of its southern coast. The NCM’s latest report indicates that these areas, along with others, are bracing for moderate to heavy precipitation. This comes as Saudi Arabia continues to address the impacts of climate change and increasingly variable weather patterns.
Understanding the Incoming Rainfall and Winter Conditions
The meteorological winter in Saudi Arabia doesn’t align precisely with the astronomical winter, which is based on the Earth’s tilt. Instead, it’s defined by specific temperature thresholds and atmospheric patterns. According to the NCM, this transition marks a shift towards cooler, more humid air masses influencing the region. This change is crucial for replenishing groundwater reserves and supporting agricultural activities.
Regional Weather Forecasts
Currently, the Jazan, Asir, and Al-Baha regions are experiencing moderate thunderstorms accompanied by hail and strong winds. Fog formation is also a possibility in these areas, as well as in the Eastern Province. These conditions require caution for travelers and outdoor workers.
Meanwhile, dust and sand storms are affecting the Makkah, Madinah, Hail, Tabuk, and Al-Jouf regions, reducing visibility and potentially impacting air quality. The NCM advises residents in these areas to take necessary precautions, such as wearing masks and avoiding unnecessary outdoor exposure. These conditions are typical for this time of year as cooler air interacts with drier land surfaces.
The Red Sea is also experiencing varied conditions. Northwesterly to northerly winds are blowing at 10-28 km/h in the northern and central parts, while southerly to southeasterly winds are prevailing in the south at 15-40 km/h, potentially reaching 50 km/h with the development of rain clouds near the Bab el-Mandeb Strait. Wave heights are expected to range from half a meter to over two meters in the southern part of the Red Sea, creating moderate to rough seas.
The upcoming rainy spell, expected to begin next Sunday, is anticipated to be more widespread and intense than recent showers. The NCM forecasts moderate to heavy rainfall impacting areas already affected, suggesting a potential for localized flooding. Authorities are likely to issue further advisories as the event approaches.
The shift towards winter also brings changes in humidity levels. Increased moisture in the air, combined with cooler temperatures, can lead to the formation of fog, particularly in low-lying areas and near bodies of water. This impacts transportation and requires increased vigilance from drivers. The increased humidity also affects human comfort levels.
The Kingdom’s diverse geography contributes to these varied weather patterns. The mountainous regions experience cooler temperatures and higher precipitation rates, while the coastal areas are influenced by sea breezes and humidity. The vast desert landscapes are prone to dust storms and rapid temperature fluctuations. Understanding these regional differences is key to accurate weather forecasting and preparedness.
The NCM’s ongoing monitoring and forecasting efforts are crucial for mitigating the impacts of these weather events. The center utilizes advanced meteorological models and observation networks to provide timely and accurate information to the public. This information allows individuals and businesses to make informed decisions and take appropriate safety measures. Weather patterns in the region are becoming increasingly complex, necessitating continuous improvement in forecasting capabilities.
Looking ahead, the NCM will continue to monitor the developing weather systems and provide updated forecasts as the rainy spell approaches. The intensity and duration of the rainfall remain uncertain, and residents are advised to stay informed through official channels. Further updates regarding potential impacts on infrastructure and transportation will be released as they become available. The focus will be on tracking the movement of the low-pressure system and assessing its potential for severe weather.
