Dolly formed on July 20 from a tropical wave, which was located north of Honduras. Since it became a tropical storm right away it never became a depression while forming. Early on July 21 Dolly made landfall in the Yucatán Peninsula. The day after that it became a hurricane. Dolly moved northwest and for a little while it was a category 2 hurricane. Dolly weakened a little, back to a category 1 later that day. Very shortly after weakening Dolly made landfall in South Padre Island, Texas. Dolly died over in a very northwestern area of Texas on July 27.
