Jordan: A new and fast-moving, third-degree weather depression will affect the Kingdom on Monday, accompanied by heavy rain and strong winds.

Arab Weather - The latest outputs of computer simulation maps indicate the formation of a new low-pressure system over the eastern Mediterranean basin, which will gradually center on Monday, December 29, 2025, to the north of Syria, and will affect the Kingdom, God willing, as a third-degree low-pressure system (moderate to highly effective).

This low-pressure system is characterized by its rapid movement and short duration, but it is effective in terms of rainfall and winds, with heavy rain expected, especially in the north of the Kingdom, coinciding with strong wind activity in the southern and eastern regions.

Details of the weather situation and the impact of the low-pressure system on the Kingdom

Monday morning and early afternoon: Very cold weather prevails in various regions, with clouds appearing at multiple altitudes, and intermittent showers of rain concentrated in the north of the Kingdom and extending to parts of the central regions.

Monday afternoon and evening: A cold front will cross the Kingdom, and the low-pressure system will reach its peak impact.

The low-pressure system will gradually intensify as a highly active cold front crosses the Kingdom, starting from the north. The skies will become completely cloudy, and rainfall will become widespread, extending from the north towards the central regions. The rain will be very heavy, with chances of lightning, thunder, and hail, which may lead to:

• The flow of valleys and ravines
• Floods form, including in the northern Jordan Valley.
• Water accumulations on roads

Low clouds also pass through, touching the ground, causing dense fog to form over high mountain peaks, leading to reduced and possibly zero horizontal visibility on some roads.

The cold front will reach the south of the Kingdom during the afternoon and evening hours.

During the afternoon and evening hours, the cold front will fully cross the Kingdom, with its effects reaching the south, including the governorates of Karak and Tafilah and the Southern Ghor. Heavy rainfall is expected, increasing the risk of flash floods and soil and rock erosion in the affected areas. Simultaneously, winds will become noticeably active in:

plains regions
The desert
Southern Highlands

Strong winds accompany the passage of the weather front

The winds will be strong, with gusts ranging between 90–100 km/h, which will stir up very dense dust waves in the eastern desert, including the Baghdad International Road.

Monday night/Tuesday morning : The low-pressure system moves rapidly away from the Kingdom and its impact gradually diminishes, with a continued chance of scattered showers, especially in the southern regions, along with cold weather.

Summary and classification of low pressure systems

* Classification: Level 3 (Medium - Highly Effective)
* Duration of effect: Fast (approximately 15 hours)
* Period of influence: From Monday morning until Monday/Tuesday night
Expected rainfall amounts: 25 – 90 mm
* Wind gusts: 90 km/h and may exceed that locally
* Temperatures: Between 4 and 10 degrees Celsius
Snow: Unexpected

Key recommendations during the weather event:

* Wear warm clothes, especially during the night and early morning hours.
* Safe use of heating appliances.
* Drive carefully and maintain a safe distance during rain and fog.
* Be aware of the risk of flash floods and overflowing valleys, especially in low-lying and southern areas.
* Beware of landslides and rockfalls, especially in the southern highlands.
* Be aware of dense fog and reduced horizontal visibility on highways.

And God knows best.
