According to the November 14 update by the UN Office for the Coordination of Humanitarian Affairs  (8 pp.), the consequences of Hurricane Haiyan (Yolanda) in the Central Philippines include:

• Over 921,000 displaced people

• Based on initial data, 243,595 houses are damaged (131,106 are totally destroyed
  and 112,489 partially damaged).

• Damaged water systems are causing limited or no water supply in affected areas. 239 municipalities do not have electricity as of 13 November. Water systems in these areas may not be fully operational as they often rely on power to pump water.

• A total of 2.5 million people are in need of food assistance. As of 17:00 on 13 November, 9,804 family food packs for 49,020 people were distributed.
