MODIS Terra and Aqua images on June 18 and June 19 have some cloud-cover problems but still show oil slick and sheen spanning areas of 11,278 square miles and 18,473 square miles respectively, with oil apaprently coming ashore from Gulf Shores, Alabama to points as far east as Seacrest and Rosemary Beach, Florida. Oil is also apparent in Pensacola Bay on the 18th:
Strong thunderstorms form large, dense masses of bright white cloud in this image — one area of cloud obscures the location of the leaking Macondo well, source of the ongoing BP / Deepwater Horizon oil spill. Oil slicks and sheen viewed through breaks in the cloud cover at least 11,278 square miles (29,210 km2). Oil appears to be making landfall along the beaches of Perdido Key, Alabama, and east along the coast to Destin, Florida. Oil slicks also seem to occur within Pensacola Bay itself. Compare with the MODIS/Aqua image taken the next day, on June 19:
Not as many thunderstorms and cloudy patches on this image, revealing the continuing upwelling of fresh oil around the location of BP’s leaking well. Slicks and sheen span 18,473 square miles (47,847 km2) on this image. Thin patches appear to be making landfall from Gulf Shores, Alabama to Perdido Key in Florida, and from Grayton Beach State Park to the Seacrest / Rosemary Beach area along the Florida coast.
