Tropical Storm Dolly was wrapped around the Yucatan Peninsula on July 21, 2008, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. Only the northern half of the storm remained intact after its passage over the peninsula from the Caribbean Sea to the Gulf of Mexico. According to the 1:00 p.m. (Central Daylight Time) advisory from the National Hurricane Center on July 21, Dolly was moving west-northwest at about 10 miles per hour, and was predicted to reach hurricane strength by late Tuesday (July 22) or Wednesday (July 23).
