- Storm brings more than a year's worth of rain
- Winds gusts reach up to hurricane strength
- Flights suspended at Abu Dhabi International Airport
The downpour quickly overmatched the drainage systems, leaving motorists stranded in standing water on city streets.
The storm, which contained strong winds, frequent lightning and even some hail, caused all flights to be suspended Wednesday at Abu Dhabi International Airport. Wind gusts reached hurricane strength -- 75 mph (120 kilometers per hour) -- at nearby Al Bateen Executive Airport.
In addition to travel chaos, schools and businesses were closed, and many were to be closed again Thursday as weather conditions were expected to remain unsettled.
Rainfall is rare in the UAE, which has a dry, desert climate that sees less than 4 inches (100 millimeters) of rainfall per year on average. Since Saturday, when the round of wet weather began, up to 11.6 inches (295 millimeters) of rain have fallen, according to a spokesman for the UAE's National Center of Meteorology & Seismology.
This type of intense rainfall can cause significant flooding and damage, especially in an urban environment without adequate infrastructure for drainage and runoff.
Though rain is rare in the UAE, February and March are the rainiest months, which see about 75% of the annual total of around 3.5 inches (90 millimeters).
The current storm system was expected to linger over the UAE and Oman through Thursday, but a drying trend is in the forecast beginning Friday.
