TROPICAL WEATHER OUTLOOK
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
200 AM HST TUE JUL 7 2015

For the central north Pacific, between 140°W and 180.

1. Showers and thunderstorms associated with a large area of low pressure located about 1300 miles east southeast of Hilo, Hawaii have continued to become better organized, and satellite wind data indicate that the surface circulation has become a little better defined overnight. Environmental conditions are expected to be conducive for further development, and a tropical cyclone will likely form later today or tonight as this system moves toward the west northwest at 15 to 20 mph.

* Formation chance through 48 hours, high, 90 percent.

2. Showers and thunderstorms persist near a weak, nearly stationary surface low located about 750 miles south southeast of Hilo, Hawaii. This system remains disorganized, and environmental conditions do not appear to be favorable for significant development in this area during the next two days.

* Formation chance through 48 hours, low, 10 percent.

3. Showers and thunderstorms associated with a broad area of low pressure located about 1100 miles south southwest of Honolulu, Hawaii increased in coverage, and have become slightly better organized overnight. Environmental conditions appear to be somewhat conducive for some slow development of this system as it moves slowly toward the north or northeast over the next couple of days.

* Formation chance through 48 hours, medium, 40 percent.

Elsewhere, no tropical cyclones are expected through late Wednesday night.
