A tropical wave emerged into the Atlantic Ocean off the west coast of
Africa during the last week of July. As it tracked across the Atlantic, it remained a well-defined system, but never organized into a tropical cyclone. On August 8, the system entered the Gulf of Mexico, and by the following day, it developed a weak low-level circulation. The circulation became better defined later that day, and was confirmed by
Reconnaissance aircraft that afternoon, when it was declared Tropical Depression Eight while east of Tamaulipas. From the outset, the cyclone's motion was altered by Hurricane Flossie off the
Pacific coast of Mexico. Initially, deep convection fired up gradually as the depression slowly tracked westward in the Gulf of Mexico. At 1200
UTC on August 10, the depression strengthened into Tropical Storm Gabrielle, as the storm curved southward. Gabrielle then strengthened slowly over the warm
sea surface temperatures in a low
wind shear environment, although land interaction slowed the intensification somewhat. The storm shifted once again onto a west-northwest course on August 11, moving very slowly towards the coast. The storm made landfall at 2000 UTC on August 11, just south of La Pesca in the Mexican state of Tamaulipas, about south of the
United States-Mexico border and about north of
Tampico. Simultaneously, Gabrielle attained its peak intensity with a maximum sustained wind speed of and a minimum barometric pressure of . After landfall, the storm rapidly weakened, deteriorating to tropical depression status by early on August 12 over northeast Mexico. Six hours later, the surface circulation of Gabrielle dissipated over the mountains of the
Sierra Madre Oriental, although its cloud pattern transited Mexico intact, moving into the
Gulf of California before it sheared across northwest Mexico on August 15. ==Preparations and impact==
