* Exports halted due to weather - sources
* Berthings at Jebel Dhanna stopped Friday - source (adds details)
DUBAI Aug 2 The United Arab Emirates halted crude exports from its Jebel Dhanna oil terminal late on Friday, and from its Jebel Ali facility on Sunday, due to a sand storm, a shipping source said.
Berthings at Jebel Dhanna were stopped on Friday night due to poor visibility caused by the storm, the Middle East-based shipping source said.
"It was shut on Friday... late night, they are trying to berth the vessels but the weather is really bad," the source said. "There is no indication when the terminal will be re-opened."
Abu Dhabi National Oil Co (ADNOC), the main oil producer for the OPEC-member, exports its crude via the Jebel Dhanna terminal.
Meanwhile, another shipping source said the Jebel Ali facility, a key export terminal for refined petroleum products such as motor gasoline, aviation fuel and diesel, had been shut on Sunday, also due to bad weather.
Oil exports from Saudi Arabia's Ras Tanura -- the world's largest offshore oil facility -- continued as normal despite "foggy weather", a port source said.
Ras Tanura has the capacity to load between 5.5 million and 6 million barrels per day (bpd) of oil.
In Qatar, its three main exporting facilities were shut down over the weekend due to poor visibility but reopened on Sunday morning. Sources expect another closure in coming days as forecasts indicate continued bad weather. (Reporting by Luke Pachymuthu and Amena Bakr; Editing by Hans Peters)
