Unstable weather conditions will affect the Kingdom on Monday, and will be particularly strong in the eastern desert regions.

Arab Weather - Computer simulation maps at the Arab Weather Center indicate that the Kingdom will be affected on Monday, April 27, 2026, by unstable weather conditions. The effects of these unstable weather conditions will be concentrated on the eastern desert regions, where they are expected to be strong, increasing the likelihood of valleys overflowing and flash floods, in addition to the possibility of heavy hail, coinciding with a clear and noticeable drop in temperatures compared to previous days.

The weather conditions in the Kingdom on Monday can be summarized as follows:

First: A noticeable drop in temperatures
Temperatures will drop significantly compared to previous days, becoming about two degrees Celsius below average for this time of year. Maximum temperatures in Amman and the various mountainous regions will range between 18 and 21 degrees Celsius.

The weather is generally cold in the morning hours, tending to be cold over the high mountain heights during the rest of the day, while it is mild in the low-lying areas.

Second: A state of atmospheric instability concentrated over the eastern desert regions (strong thunderclouds accompanied by heavy rain, intense hail showers and sudden winds).

Advanced computer modeling maps indicate that the Kingdom will be affected, God willing, by a state of atmospheric instability on Monday. Its effects will be strongest in the eastern desert regions, with thunderstorms developing during the afternoon and evening hours, accompanied by heavy rain and hail of varying sizes. These storms may also be accompanied by sudden downdrafts that could lead to the formation of localized and dense dust storms within the thundercloud areas. The strongest effects of this atmospheric instability will extend to areas east of Mafraq Governorate, the Jordanian-Iraqi border, and the international highway leading to Iraq (Baghdad International Highway).

Therefore, truck and vehicle drivers on this road are advised to be careful, given the high risk of flash floods that may impede traffic or cut off parts of the road, in addition to the possibility of sandstorms on the road that may cause a lack of or perhaps a sharp decrease in horizontal visibility on some sections.

As for the rest of the Kingdom’s regions, during the afternoon hours of Monday, clouds will increase at different altitudes, and there will be a chance of thunderstorms in random areas, including the Jordan Valley and the Dead Sea. It is not unlikely that the rain will be heavy at times in some cities and neighborhoods more than others, and it may be accompanied by hail in some narrow geographical areas.

Evening and night: The intensity of the unstable weather conditions decreases.

During the evening and night hours, the weather will be cold and humid in all regions, coinciding with the decline in the effects of the unstable weather conditions in various regions, but with the continued possibility of some thunderstorms, especially in the eastern desert regions.

Recommendations during the period of atmospheric instability concentrated in the eastern part of the Kingdom:

• Stay away from valleys, flood channels, ravines, and areas where water usually collects, especially in the east of the Kingdom.
• It is necessary to be aware of the same dangers and to stay away from valleys in desert areas, and this includes those living in tents.
• Be careful while driving on roads where rain has started to fall, for fear of slipping.
• Take shelter inside buildings when lightning strikes.
• Be aware of the formation of flash floods and rising water levels in some areas, especially in the east of the Kingdom.
• Be aware of reduced visibility due to dust caused by downdrafts associated with thunderstorms, especially in the desert regions of the Kingdom.

And God knows best.
