Tropical Storm Frank - August 6-12, 1998

A tropical wave with cyclonic turning moved off the coast of Africa on July 19th.  Weakening as it moved
westward, the wave travelled across the tropical Atlantic and Caribbean before crossing Central America on
July 31.  Thunderstorm activity with the wave increased, but did not show organization until August 4th.  The
organized into a tropical depression by the morning of August 6th, 480 miles south of the tip of Baja California.
Moving northward due to a mid-level trough west of the United States, the cyclone became a tropical storm late
on the 7th.  Turning north-northwest parallel to the Baja California peninsula, Frank spread heavy rains across
the southern portion of the peninsula.  Moving into cooler waters, the system weakened back into a tropical
depression, and eventually a remnant low.  Below is a track of the cyclone, prepared by the National Hurricane
