The National Weather Service’s Central Pacific Hurricane Center continues to keep a watchful eye on a low pressure system in the Central North Pacific.


In an 8 a.m. update, CPHC says the storm has a 90 percent chance of becoming a tropical cyclone in the next 48 hours.

As of Tuesday morning, the system was about 1,300 miles to the east-southeast of Hilo and has organized itself. CPHC officials say environmental conditions will remain conducive for further development.

It’s estimated that a tropical cyclone will be formed later Tuesday as the system moves to the west-northwest at a rate of 15 to 20 miles per hour.


Two additional storms in the area also continue to be monitored. A nearly-stationary weak surface low is currently located about 750 miles to the south-southeast of Hilo. CPHC officials say the disorganized system has environmental conditions that are not likely to further its development. Chances of formation remain low at 10 percent.

Another storm system, described as a broad low pressure area about 1,100 miles to the south-southwest of Honolulu, is gradually organizing. The storm has environmental conditions that are conducive for development. CPHC officials say the system has a medium chance at 40 percent to form in the next 48 hours.
