An upper low dropped into the northeast Gulf of Mexico and retrograded westward. An area of convection
led to the formation of a surface low south of the Gulf coast on August 5th, which moved westward. The system
became a tropical storm as it passed south of Louisiana. Abby was an extremely small storm, with a complete surface
circulation less than 100 miles in diameter. Abby moved west near 10 mph before it struck the coast just northeast of
Matagorda as a moderate tropical storm late in the afternoon on the 7th. The system weakened after landfall, losing its
identity as it crossed south-central Texas. The graphics below show the storm total rainfall for Abby, using data
provided by the National Climatic Data Center in Asheville, North Carolina.
