Hurricane Guillermo let the eastern Pacific and entered the central north Pacific region early this afternoon. At 2 pm, Guillermo was about 1145 miles east-southeast of Hilo and moving west-northwest near 15 miles an hour.

Besides Guillermo, several other areas of thunderstorms surrounded the Hawaiian islands. An area of isolated thunderstorms Sat between 139°W and 145°W from 23°N to 26°N this afternoon. This area of thunderstorms had tops around 44000 and was associated with a west to east jet stream passing overhead.

An area of more widespread and stronger thunderstorms occupied the area from 167°W to 179°W between 12°N and 19°N. Storm tops in this area rose to between 50000 and 55000 feet. The storms were forming in the vicinity of a couple of surface trough migrating westward through the area.

The remnant of post-tropical cyclone Eight-E was centered about 300 miles south-southeast of Hilo. It was moving west at 10 to 15 miles an hour. Isolated thunderstorms that had formed near its center this morning had nearly all dissipated by early afternoon. This remnant was currently no more than a weak surface trough.

Still another area of isolated thunderstorms was located from 29°N to 33°N between 162°W and 167°W. These storms were associated with an upper low near 33°N 169°W. The upper low was moving east near 15 miles an hour.

Clusters of mostly broken, showery low clouds were affecting the windward sections of the Big Island and Maui. These clouds were associated with the cloudiness along the northernmost fringes of the remnant of Eight-E mentioned above.

At 2 pm, skies were cloudy along the windward side of the Big Island and along the lee side from Kona to South Point to Naalehu. Maui was mostly cloudy along the windward sections and along some of south slopes of Haleakala. The interior parts of Kauai were mostly cloudy as well. But the rest of the state was mostly sunny to partly cloudy. The low clouds near the islands were moving west-southwest at 20 to 25 miles an hour.
