Airport authorities have announced several flights to Dubai were cancelled and diverted yesterday, after heavy rains hit the United Arab Emirates for the second time in a month.

An airport authority spokesperson said five inbound flights were diverted overnight, while nine arriving and four departing flights were cancelled.

Authorities warned residents to stay home ahead of yesterday’s rain, announcing that they should work remotely, and that schools will hold classes online.

In April, heavy thunderstorms dumped the heaviest rains ever recorded in the UAE in a span of hours, flooding portions of major highways and Dubai International Airport, the world’s busiest for international travel.

The airport ended up needing 22 tankers with vacuum pumps to get water off its grounds.
