Tropical Weather Outlook
NWS Central Pacific Hurricane Center Honolulu HI
200 AM HST Sat Aug 12 2023
For the central North Pacific...between 140W and 180W:
1. Far east-southeast of the main Hawaiian Islands:
A broad area of low pressure associated with a tropical wave is
producing a large area of disorganized showers and thunderstorms
located about 1600 miles east-southeast of Hilo, Hawaii.
Conditions appear conducive for development of this system, and a
tropical depression is likely to form during the next few days
while moving toward the west or west-northwest at about 10 mph
across the far western portion of the east Pacific basin,
crossing into the Central Pacific basin late Sunday.
* Formation chance through 48 hours...medium...near 50 percent.
* Formation chance through 7 days...high...70 percent.
2. Central East Pacific (EP98):
Showers and thunderstorms continue to show signs of organization
in association with an area of low pressure located about 2900
miles east-southeast of Hilo, Hawaii. However, satellite-derived
wind data from overnight indicated that the system did not yet have
a well-defined center of circulation. Environmental conditions are
conducive for additional development of this system, and a tropical
depression is expected to form during the next day or two while it
moves westward or northwestward at about 10 mph across the central
portion of the east Pacific basin. This system, if it develops,
may cross into the Central Pacific basin next Thursday or Friday.
* Formation chance through 48 hours...medium...80 percent.
* Formation chance through 7 days...high...90 percent.
Elsewhere, no tropical cyclones are expected during the next 7 days.
