Over the next two days, certain regions in the UAE can anticipate thunderstorms and rain according to the National Centre of Meteorology.
The Intertropical Convergence Zone (ITCZ) is influencing the weather in the United Arab Emirates (UAE) by extending and moving from the south towards the country. This movement, accompanied by the advancement of surface and upper-level low-pressure systems, is causing convective cloud formation, leading to expected thunderstorms, rain, lightning, and strong winds primarily over the eastern and southern regions of the UAE, extending into some internal areas[1][3][4].
From August 20 to 21, 2025, these weather patterns result in:
- Rainfall varying in intensity with thunderstorms and lightning in scattered parts of eastern and southern UAE.
- Convective clouds intensified by the eastern mountains aiding rainfall formation.
- Winds shifting from south-easterly to north-easterly, with moderate to occasional strong gusts that can raise dust and sand, reducing horizontal visibility.
- Sea conditions are expected to be slight to moderate in the Arabian Gulf and Sea of Oman[1][4].
The UAE, situated on the northern edge of the ITCZ’s influence during late summer, experiences this seasonal migration of moist air and convective activity, particularly affecting coastal and mountainous eastern and southern locales.
The National Centre of Meteorology (NCM) has stated that this is due to the extension of the Intertropical Convergence Zone (ITCZ) and its movement from the south towards the country[2]. No new information about the movement of the ITCZ, the advancement of low-pressure systems, or the flow of moist air masses is provided.
In summary, the ITCZ's southern advance is triggering moist air inflow and low-pressure dynamics that generate thunderstorms and rain mainly over eastern and southern UAE zones, with moderate to strong winds and possible dust in these areas over the named dates[1][3][4]. Residents are advised to stay updated on weather conditions and take necessary precautions during this period.
