Thunderstorms and dust storms will affect nine Saudi regions on Sunday.

The latest updates issued by the National Center for Meteorology indicate the start of an unstable weather condition affecting several regions of the Kingdom of Saudi Arabia starting from Sunday, June 28, 2026, where cumulonimbus clouds become clearly active and the chances of rainfall are renewed at intermittent intervals, which may be accompanied locally by heavy showers that lead to the formation of flash floods in some valleys and low-lying areas.

The data shows that the active summer weather will continue over the Kingdom, which enhances the chances of thunderstorms forming during the afternoon hours, especially over the southern and western highlands.

Thunderstorms expected in 9 regions

Forecasts indicate continued chances of thunderstorms in the Jazan, Asir and Al-Baha regions, with rainfall ranging from light to moderate, and the possibility that it may sometimes be accompanied by locally heavy showers with lightning, thunder and hail.

Downdrafts associated with thunderstorms are also active, which may lead to strong winds that stir up dust and sand, and a decrease in horizontal visibility in some locations.

Dust-raising winds

The forecast also indicates surface wind activity that will stir up dust and sand in parts of the eastern regions, and may extend to Najran, Medina, Hail and parts of Mecca.

Warning from the National Center for Meteorology

The National Center of Meteorology warns of the need to follow updates continuously, due to the possibility of thunderstorm activity and the accompanying lightning, hail, and flash floods in some areas.
