As Tropical Storm Andres neared the coast of El Salvador, an area of strong low level flow developed
west of the 100th meridian.  A tropical disturbance developed within the Gulf of Tehuantepec, which
organized into Tropical Depression 2E on June 9th.  Quickly organizing into a tropical storm, Blanca
moved west-northwest offshore the coast of southern Mexico.  Reaching its peak intensity late on the
10th, the system weakened thereafter, losing its closed circulation center by the morning of the 12th.
