Forecasters in the Central Pacific are watching a broad area of low pressure associated with a tropical wave south and east of the Big Island that has a chance to become a tropical cyclone.
It’s too early to tell, however, if it or two other developing systems in the Eastern Pacific will impact the Hawaiian Islands.
As of 8 a.m. Aug. 12, the Central Pacific Hurricane Center in Honolulu said the low pressure system was located about 1,400 miles east-southeast of Hilo and was producing a large area of disorganized showers and thunderstorms.
Conditions appear conducive for further development of this system, with a tropical depression likely to form during the next few days while it moves toward the west or west-northwest at about 10 mph. The system is still in the Eastern Pacific, but expected to cross into the Central Pacific late Sunday.
Right now, it has a 60% chance of becoming a tropical cyclone in the next 48 hours and an 80% chance during the next seven days.
Showers and thunderstorms also continue to become better organized in another low pressure system located several hundred miles south-southwest of the southern tip of the Baja California peninsula in the central East Pacific.
It appears a tropical depression or tropical storm could be forming, with a 90% chance of formation in the next two days and 90% chance during the next week.
The low pressure system is expected to move west to west-northwest at about 10 mph across the central portion of the East Pacific during the next few days. If a tropical depression or storm develops, it could cross into the Central Pacific next Thursday or Friday.
According to the National Hurricane Center in Miami, Fla., a third low pressure system is forecast to form off the west coast of southern Mexico in the Eastern Pacific during the next couple of days. It is associated with a tropical wave moving across the southern portion of Central America.
Environmental conditions are expected to be conducive for further development, and a tropical depression is likely to form during the early or middle part of next week while the system moves generally west-northwest, roughly parallel to the coast of southern and southwestern Mexico.
The chances of the low pressure system becoming a tropical cyclone in the next 48 hours is at just 10%, but it increases to 80% in the seven-day outlook.
There are no other tropical cyclones expected elsewhere during the next week.
