REMARKS: Possible oil was observed in satellite imagery. This anomaly is unconfirmed as oil. The anomaly is believed to be remnant oil from a spill reported in NRC hotline 10692. The spill was very well defined across most of the extent with more diffuse portions closer to the Mississippi Delta. The trailing edge of the remnant oil was about 23 nm from the suspected point source originally reported in the hotline. The slick measured approx. 28.7 nm long and had a maximum width of 9 nm. The slick was oriented in agreement with NE winds that were 10-15 kts at the time of the image.

UNCERTAINTIES: The slick likely extended beyond the image boundary, so a more precise measure of the slick's area was not possible. However, it's likely that more diffuse oil impacted the shoreline near Port Eads, LA.
