Original warning text
Mystery Spill - San Juan Harbor; Isla Grande, Puerto Rico. Isla Grande, Puerto Rico. 1. At 0725 on January 15, 1998, a harbor master reported a slick in San Juan Harbor. Initially the amount of oil was estimated to be 500 gallons of heavy fuel oil, type unknown; the source of the spill was also unknown. The USCG investigated and determined that the slick was 1/4 to 1/3 mile long and the amount of oil in the water was about 3000 gallons. The slick was fragmented and contained large patches of oil 15 to 20 feet in diameter, but it was not sheening significantly. Throughout the morning, the slick moved little, but was drifting to the southwest, being pushed by northeasterly winds. USCG district 7. Keyword: skimmers. 2. COMMODITY: HEAVY FUEL OIL. MAXIMUM POTENTIAL RELEASE: 3000 GALLONS. 3. POSITION 18.450N 066.117W. NOAA INCIDENTNEWS 7180: https://incidentnews.noaa.gov/incident/7180
