- Visibility reduction causing airport closure and road accidentsKuwait Times - 22 June, 2008Sand storms in the northern Gulf have disrupted oil exports for several days from OPEC members Iraq and Kuwait. The storms had prevented seven of eight ships from docking there since Saturday.
1. More than 500 traffic accidents were reported in Kuwait within 48 hours on Thursday and Friday, while in Bahrain a further 20 accidents were reported, according to local media.
2. Hospitals in all three Gulf states reported large numbers of patients being admitted with respiratory problems. In Bahrain, more than 150 people required hospital treatment, Bahrain's Gulf Daily News reported.
3. The adverse weather conditions also caused some problems at airports around the region, with both Bahrain and Kuwait reporting minor disruption.

WMO SDS-WAS History
14th session of CBS in Dubrovnick (25 March-2 April 2009) requested CBS experts to review the draft SDS-WAS Implementation plan to clarify the SDS-WAS Center (Nodes) in the context of the WMO Global Data Processing and Forecasting System (GDPFS) and Regional Specialized Meteorological Center (RSMC) structures.
CBS reviewed SDS-WAS IP in 13 Oct 2009 and accepted by WMO-CAS on its XV Session in Incheon Korea (18-25 November 2009)
CAS recommended for the WMO Secretariat to appoint a small ad-hoc joint task team with representatives from the CBS Open Programme Area Group for Data Processing and Forecasting System (OPAG-DPFS) and CAS to prepare an amendment to the GDPFS manual in association with operational aspects of SDS-WAS
The ad-hoc joint task team was formed in July 2010* Experts from CBS and two SDS-WAS regional nodes
