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

The National Hurricane Center is issuing advisories on Tropical
Storm Karina, located more than a thousand miles east-southeast of
the Big Island of Hawaii, and on Hurricane Lowell, located a little
more than 800 miles west of the southern tip of the Baja California

Showers and thunderstorms associated with a large area of low
pressure located several hundred miles south-southeast of Acapulco,
Mexico, have continued to become better organized over the past
several hours. Environmental conditions are conducive for
development, and any additional increase in organization would
result in the formation of a tropical depression later tonight or on
Friday while the system moves west-northwestward at about 10 mph. In
addition, satellite-derived wind data indicate that gale-force winds
are occurring well to the northeast of the low near the Gulf of
Tehuantepec, which are not part of the circulation at this time.
Information on this gale area is contained in High Seas Forecasts
issued by the Tropical Analysis and Forecast Branch.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

High Seas Forecasts issued by the Tropical Analysis and Forecast
Branch can be found under AWIPS header MIAHSFEP1 and under WMO
header FZPN01 KWBC.
