Tropical Storm Abby - August 4-9, 1964

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.
