The MODIS flying on NASA's Aqua satellite captured this image of Hurricane Dean at 3:45 p.m. local time (19:45 UTC) on August 22, 2007, as the storm was plunging inland over Mexico towards the high mountain ranges that form the spine of Mexico. Making landfall with 100-mile-per-hour sustained winds, Dean lost strength over land. The storm still possessed the signature spiral structure of a hurricane, but the central eye appeared to be gone by the time MODIS observed the storm. On the right side of the image, the usually dark blue waters of Campeche Sound are pale where Dean's powerful winds churned up a trail of sand and sediment. Hurricane Dean was the fourth named storm and the first hurricane of the 2007 Atlantic season. It was one of the strongest hurricanes ever observed in the Atlantic Basin. Dean reached Category 5 status on the Saffir-Simpson Hurricane Scale on August 20 as it passed over the deep, warm waters of the Caribbean. When it came ashore on August 21, it was the first storm to make landfall as a Category 5 hurricane in the Atlantic basin since Hurricane Andrew in 1992.
