Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Iona, located in the central Pacific basin well south of the
Hawaiian Islands, and on Tropical Storm Keli also located in the
central Pacific basin well southeast of the Hawaiian Islands.
Western East Pacific (EP98):
Showers and thunderstorms associated with an area of low pressure
located around 1150 miles east-southeast of the Hawaiian Islands
remain limited and have changed little since this morning. However,
if persistent showers and thunderstorms re-develop during the next
day or so, a short-lived tropical depression could still form. The
system will enter the Central Pacific basin shortly.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...medium...60 percent.
South of Southwestern Mexico (EP99):
A trough of low pressure located several hundred miles southwest of
the southwestern coast of Mexico is producing a large area of
disorganized showers and thunderstorms. Environmental conditions
appear conducive for development, and a tropical depression is
likely to form during the next day or two while the system moves
west-northwestward around 15 mph, remaining well offshore of the
southwestern coast of Mexico.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.
Central East Pacific:
An area of low pressure is forecast to develop well south of
southern or southwestern Mexico late this week. Environmental
conditions appear conducive for some gradual development of this
system and a tropical depression could develop over the weekend or
early next week as the system moves west-northwestward at 10 to 15
mph.
* Formation chance through 48 hours...low...near 0 percent.
