Storm dumps heaviest rain ever recorded in desert nation of UAE
The state-run WAM news agency called the rain Tuesday “a historic weather event” that surpassed “anything documented since the start of data collection in 1949.” That's before the discovery of crude oil in this energy-rich nation then part of a British protectorate known as the Trucial States.
Rain also fell in Bahrain, Oman, Qatar and Saudi Arabia. However, the rains were acute across the UAE. One reason may have been “cloud seeding,” in which small planes flown by the government go through clouds burning special salt flares. Those flares can increase precipitation.
Several reports quoted meteorologists at the National Center for Meteorology as saying they flew six or seven cloud-seeding flights before the rains. The center did not immediately respond to questions Wednesday, though flight-tracking data analyzed by The Associated Press showed one aircraft affiliated with the UAE’s cloud-seeding efforts flew around the country Sunday.
The UAE, which heavily relies on energy-hungry desalination plants to provide water, conducts cloud seeding in part to increase its dwindling, limited groundwater.
The rains began late Monday, soaking the sands and roadways of Dubai with some 20 millimeters (0.79 inches) of rain, according to meteorological data collected at Dubai International Airport. The storms intensified around 9 a.m. local Tuesday and continued throughout the day, dumping more rain and hail onto the overwhelmed city.
By the end of Tuesday, more than 142 millimeters (5.59 inches) of rainfall had soaked Dubai over 24 hours. An average year sees 94.7 millimeters (3.73 inches) of rain at Dubai International Airport, a hub for the long-haul carrier Emirates.
At the airport, standing water lapped on taxiways as aircraft landed. Arrivals were halted Tuesday night, and passengers struggled to reach terminals through the floodwater covering surrounding roads.
Emirates said the airline had halted check-in for passengers departing from Dubai itself from 8 a.m. until midnight Wednesday as it tried to clear the airport of transit passengers — many of whom had been sleeping where they could in its cavernous terminals.
Schools across the UAE, a federation of seven sheikhdoms, largely shut ahead of the storm and government employees were largely working remotely if able. Many workers stayed home as well, though some ventured out, with the unfortunate stalling out their vehicles in deeper-than-expected water covering some roads.
Authorities sent tanker trucks out into the streets and highways to pump away the water. Water poured into some homes, forcing people to bail out their houses.
Meanwhile in neighboring Oman, a sultanate that rests on the eastern edge of the Arabian Peninsula, at least 19 people were killed in heavy rains in recent days, according to a statement Wednesday from the country's National Committee for Emergency Management. That includes some 10 schoolchildren swept away in a vehicle with an adult, which saw condolences come into the country from rulers across the region.
