WASHINGTON -- In Puerto Rico, enhanced communications and completed assessments are providing a clearer picture of the extent of the storm damage and the magnitude of the response challenge, Defense Department spokesman Army Lt. Col. Jamie Davis said yesterday."Given the changing scope and conditions, DOD will adjust its concept of operations in Puerto Rico and transition from a short term, sea-based response to a predominantly land-based effort designed to provide robust, longer term support to [the Federal Emergency Management Agency] and [to Puerto Rico]," Davis said. The situation in the U.S. Virgin Islands continues to improve, he said, noting that the governor is shifting from response to recovery.In Puerto Rico, response operations continue as synchronization of efforts between the Title 10 forces, Puerto Rico National Guard and FEMA improve. Fuel distribution remains the top FEMA priority. Multiple DOD elements delivered fuel and continue route clearance operations. Fifty nine of 69 hospitals are operational with unknown status. Roughly 44 percent of the population remains without drinking water. The San Juan Airport and nine other airports are open. Three seaports are open and five are open with restrictions.In the U.S. Virgin Islands, the J.F. Luis Hospital in St. Croix has been found to be structurally sound.
