Heavy rain and hail hit parts of the UAE on Saturday, with strong winds causing trees to uproot in some areas. Downpours fell in Al Ain, with flooding reported in Al Fou’ah area, causing motorists to pull over as traffic was brought to a standstill. Abu Dhabi resident Matthew Walker, 46, was at the summit of Jebel Hafeet, one of the UAE's highest mountains, when the temperature dropped sharply and the rain and hail started. "I remember checking the temperature gauge in the car when we were in Al Ain city and it was 47°C. At the summit it dropped to 38°C then down to 16°C when the rain started," he said. "We pulled into a hotel at the top of the mountain at about 4.30pm and within minutes the skies turned eerily grey and the lightning and thunder started. "The rain and hail was torrential, it was battering my car. After about 30 minutes or so we decided to leave and make our way down the mountain. “There was a deluge of water cascading on to the road and there was a rock fall too. People were pulling over in their cars and taking videos because it was weird to see such a thunderstorm in the middle of June in the UAE.” At the foot of Jebel Hafeet, Mr Walker, a business development manager, said police were directing traffic around trees that fallen onto the road. Traffic lights in some areas were also down due to the battering wind and rain. Videos posted to the National Centre of Meteorology's social media showed rainwater racing down wadi beds and roads. In some areas, cars were at a standstill as the torrential downpours and hail reduced visibility. Lightning was also recorded on videos, with crashing thunder heard shortly after each flash. The storm lasted for about 90 minutes before calm was restored. Mr Walker said at about 6.30pm the temperature gauge in his car climbed back up to the high 30s. Dr Ahmad Habib, of the NCM, said the rain in Al Ain could continue for a few more days. “The cloud formation reported in Al Ain on Saturday was caused by an easterly flow coming from the Oman Sea and the Arabian Gulf,” he said. “It caused moderate to heavy rain, but this is normal for this time of the year. “At the start of summer weather like this is associated with an easterly flow and it is an extension of the monsoon-type conditions witnessed in places like India.” He said humidity levels reached about 95 per cent in Al Ain during the rain, but will slowly drop to about 80 per cent over the next few days.
