Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 0000 UTC surface analysis and satellite imagery through
0300 UTC.
...SPECIAL FEATURES...
Tropical Storm Karina is centered near 11.9N 112.7W at 28/0300
UTC, moving northwest at 11 kt. Estimated minimum central
pressure is 1000 mb. Maximum sustained wind speed is 45 kt with
gusts to 55 kt. Peak seas are currently around 15 ft (4.5 m).
Numerous moderate to strong thunderstorms extend 240 nm in the NW
and 120 nm SE semicircles. Karina is moving toward the west-
northwest and this general motion is expected to continue over
the next several days, reaching its closest point of approach to
Clarion Island late Fri night into early Sat. Strengthening is
anticipated, and Karina is forecast to become a hurricane over
the weekend. Swells generated by Tropical Storm Karina will begin
to affect portions of the coast of southwest Mexico and the Baja
California Peninsula this weekend. These swells are likely to
cause life- threatening surf and rip current conditions. Please
consult products from your local weather office. Please read the
