Tropical Storm Iselle Threatens Baja Mex

For the eastern North Pacific...east of 140 degrees west longitude..

The National Hurricane Center is issuing advisories on Tropical
Storm Iselle...located about 300 miles west-southwest of Manzanillo
Mexico.

An area of low pressure is located about 900 miles southwest of the
southern tip of Baja California Mexico. The low has a well-defined
surface circulation and is producing some persistent
thunderstorms...but that activity is displaced from the low center.
Upper-level winds are forecast to become a little more conducive
for development during the next couple of days...so there is some
potential for this system to become a tropical depression within
the next couple of days as it moves very little.

Elsewhere...tropical cyclone formation is not expected during the
next 48 hours.
