Tropical Storm Douglas - June 18-23, 1990
A tropical wave moved off the coast of Africa on June 5th. The
system moved westward across the tropical Atlantic
and Caribbean sea with minimal development, entering the eastern north
Pacific ocean on the 16th. Slowly developing,
the system became organized enough to be considered a tropical
depression late on the 18th. The system initially moved
west-northwest south of a weak high pressure area. The system
became a tropical storm southwest of Acapulco while
turning to the northwest during the afternoon of the 19th.
Douglas' center came within 15 nautical miles of the Mexican
coast during the night of June 21st and began to weaken due to the
nearby mountainous terrain. Turning west-northwest,
Douglas continued to weaken and dissipated as a tropical cyclone during
the afternoon of the 24th. Below is the
storm, provided by the National Hurricane Center.
