Tropical Storm Bertha - August 3-9, 2002
This cyclone originated within an old frontal trough in the Gulf of
Mexico on the 3rd. By the afternoon
of the 4th, it had organized into a tropical depression, before heading
northwest into Louisiana as a
tropical storm late on the 4th. Once the center headed west of
Slidell, a northeast- southwest oriented
high pressure ridge blocked its previous movement, forcing the cyclone
west-southwest. It weakened
into a tropical depression, then moved back out into the Gulf of Mexico
before striking Texas on the 9th
and dissipating. Below is the track of Bertha, furnished by the
National Hurricane Center.
