Hurricane Bret - August 16-29, 1999

A tropical wave moved off the west coast of Africa on August 5th.  It moved westward with no
development as it tracked through the tropical Atlantic and Caribbean Sea.  The wave crossed
the Yucatan peninsula on the 18th, as an upper low was moving in tandem but ahead of the
wave axis.  Development ensued, and a tropical depression formed around noon on the 18th
in the Bay of Campeche.  Wind shear slowed strengthening, but the depression did manage
the become a tropical storm late on the 19th.  The upper low allowed Bret to move north,
which was also through an area of very warm water temperatures.  It quickly strengthened
into a hurricane, and became a category four hurricane on the morning of the 22nd, while
it was approaching Texas.  Feeling the effects of a high pressure ridge to its north, Bret
moved on a more westward course, and struck the least populated coastal county in
Texas, Kenedy.  It continued to move westward, and lost all identity at the surface by
th 25th, although its mid level vorticity maximum survived to move westward another
few days.  It was the first hurricane to strike Texas in ten years, and the first major
hurricane to hit the Lone Star State in 16 years.  The track of Bret is below, provided

On the graphics below are the storm total rainfall for Bret.  Note the maximum just
south of Corpus Christi, which is just to the right of where the storm made landfall,
and a secondary maximum near Del Rio, as the circulation was forced to go up the
higher elevation, squeezing out additional heavy rains.  This maps below were generated
using data provided by the National Climatic Data Center, the Southern Region
Climate Center, and Mexico's Comision del Agua, the parent agency of their National
Weather Service.
