Eighteen people died in the floods in Oman, and the search is on for the missing. As a result of heavy rains, floods also hit Dubai in the neighboring United Arab Emirates (UAE).
Rain began to fall overnight, and people left their cars in flooded streets.
Strong winds also disrupted air traffic at the Dubai International Airport, which is the busiest in the world when it comes to international transfers, reports AP.
Schools across the UAE have been closed ahead of the storm, with civil servants working from home.
Authorities sent tankers onto streets and highways to pump out the water.
Rain is not common for the area on the arid Arabian Peninsula, so many streets have no drainage.
It is estimated that more than 30 millimeters of rain fell in Dubai during the morning, and as much as 128 millimeters is expected.
It also rained in Bahrain, Qatar and Saudi Arabia.
