Weather tracker: Thunderstorms drench UAE and Saudi Arabia

An unusual weather pattern unleashed severe thunderstorms across parts of the Middle East last week, battering countries including the United Arab Emirates and Saudi Arabia. The Arabian Peninsula – typically dominated by arid desert climates – received up to 150mm of rain in just a few days.The deluge was caused by an abnormally strong jet stream, which helped a deep area of low pressure to develop north of Saudi Arabia. This, in turn, drew moist tropical air from the Indian Ocean and triggered intense storms.In Oman, hailstones as large as tennis balls fell during Wednesday evening’s storms, alongside torrential rain. Doha, Qatar’s capital, experienced flooding the same day.A flooded street in the United Arab Emirates.

Gusts of up to 80mph, large hail and intense lightning were reported, as heavy rainfall caused widespread flooding.While thunderstorms are not rare in the region – Dubai endured extreme flooding from a storm system in April 2024 – the multiday nature of last week’s deluge is more commonly seen in the US and central Europe in spring and summer.A weather station on Jebel Yanas in northern UAE recorded 244mm of rainfall, with many others exceeding 100mm in just a few days, far surpassing typical annual totals of 60-100mm. The event reflects a broader global trend of storms bringing more intense rainfall as the climate warms.Flooded fields in Aydın, Turkey.
