The UAE Ministry of Interior has issued a weather safety warning ahead of forecast rain, thunderstorms, lightning, possible hail and strong winds on Wednesday, October 21, 2026. Residents, motorists and people planning outdoor or coastal activities should take precautions, particularly in areas affected by heavy rain, reduced visibility and water accumulation.
- Location: Parts of the UAE, particularly eastern areas and some inland and western regions
- Organisation: UAE Ministry of Interior and National Centre of Meteorology (NCM)
- Status: Weather warning issued on October 20, ahead of the October 21 forecast
- Who is affected: Residents, motorists, beachgoers and outdoor workers
- Practical impact: Potential travel disruption due to rain, dust and reduced visibility
- What’s next: Residents should monitor official weather updates as conditions develop
The UAE weather alert for October 21 warns of possible rain, thunderstorms, lightning, hail and strong winds across parts of the country. The Ministry of Interior has urged residents to exercise caution, reduce driving speeds, avoid wadis and stay away from beaches and the sea during unsettled conditions.
The warning follows a forecast from the National Centre of Meteorology (NCM), which expects convective clouds to develop over eastern areas before potentially extending towards parts of the interior and western regions. Rainfall may vary in intensity, while winds could reach 50 km/h during cloud activity.
Residents should remain alert to changing conditions, especially when travelling or planning outdoor activities.
What Is the UAE Weather Forecast for October 21?
According to the NCM forecast reported on October 20, conditions are expected to be generally fair to partly cloudy, with a chance of convective cloud formation and rainfall in some areas during the afternoon.
Eastern parts of the UAE may experience cloud development first, with some systems extending towards inland and western locations. Thunderstorms and lightning are possible, while hail may occur in areas affected by stronger convective clouds.
The forecast does not mean every emirate will experience rain. Weather conditions may vary by location, so residents should check local updates before travelling.
Winds are expected to be southeasterly to northeasterly, with speeds of 10 to 25 km/h. They may strengthen during cloud activity, reaching 50 km/h at times. These winds could also raise dust and reduce visibility on roads.
Why Has the Ministry of Interior Issued a Weather Warning?
The Ministry of Interior issued its warning to help residents prepare for potentially hazardous conditions associated with rain, thunderstorms and strong winds.
Heavy rainfall can lead to water accumulation on roads and rapid water flow through wadis. Strong winds and blowing dust can also affect driving conditions, while thunderstorms may create additional risks for people outdoors.
The warning is particularly relevant to motorists travelling through areas affected by poor visibility or rainfall. Residents should avoid assuming that roads or outdoor locations are safe simply because conditions appear clear at the start of a journey.
The NCM’s forecast also points to the possibility of humid conditions overnight and early Thursday morning, with light fog possible in some coastal and inland areas.
What Safety Precautions Should UAE Residents Follow?
The Ministry of Interior has advised motorists to reduce speed, remain alert and follow official safety instructions during the unsettled weather.
Residents can take the following precautions:
- Drive carefully: Reduce speed in rain, maintain a safe distance from other vehicles and avoid sudden braking.
- Stay away from wadis: Do not enter wadis during rainfall or attempt to cross flowing water.
- Avoid waterlogged areas: Use caution around low-lying roads and locations where rainwater may accumulate.
- Stay away from beaches and the sea: Follow the ministry’s warning and postpone coastal activities during the unsettled conditions.
- Prepare for reduced visibility: Allow extra travel time if dust, rain or fog affects the route.
- Check official updates: Monitor NCM forecasts and Ministry of Interior announcements for changes to the warning.
People planning outdoor activities should also consider postponing them if thunderstorms or strong winds affect their area.
What Temperatures Are Expected Across the UAE?
Despite the possibility of rain in some areas, daytime temperatures are forecast to remain relatively high.
The NCM forecast cited in the report gives the following expected maximum temperatures:
- Dubai: 39°C
- Sharjah: 39°C
- Abu Dhabi: 38°C
- Al Ain: 40°C
- Liwa: 40°C
- Fujairah: 33°C
These are forecast highs rather than confirmed readings. Actual temperatures may vary depending on cloud cover and local weather conditions.
The NCM also expects humidity to increase overnight and into Thursday morning in some coastal and inland areas. Light fog could develop in places, potentially affecting visibility during early-morning travel.
Sea conditions are forecast to remain slight in both the Arabian Gulf and the Sea of Oman. However, the Ministry of Interior’s advice to stay away from beaches and the sea during the unsettled weather should still be followed.
How Long Could the Unsettled Weather Continue?
A report published by Khaleej Times on October 20 cited NCM meteorologist Dr Ahmed Habib, who linked the unsettled conditions to a low-pressure system extending towards the UAE and an upper-atmosphere trough.
The report also noted that moisture moving from the Arabian Sea was contributing to cloud formation. Eastern and mountainous areas were among the locations susceptible to rainfall, with the possibility of water flowing through wadis.
The weather system was expected to weaken gradually around October 23 and 24, although remaining atmospheric moisture could continue supporting cloud development.
This outlook is subject to change. Residents should rely on the latest NCM forecasts rather than treating the expected timeline as a guarantee that all affected areas will return to settled conditions on a particular date.
The weather warning is important for anyone travelling, working outdoors or planning activities across the UAE on October 21. Rain, dust and strong winds can affect road visibility, while water flowing through wadis can create serious hazards.
Following official advice can help residents make safer travel decisions and avoid potentially dangerous locations. Businesses with outdoor operations and people planning coastal activities should also account for changing conditions.
The next step is to monitor updates from the NCM and Ministry of Interior, particularly if rainfall or thunderstorms develop in the area.
