Across the main Hawaiian islands, broken low clouds cover the interior and windward sections of Kauai. Broken low clouds also cover the windward slopes of the Koolau range on Oahu. Across Maui county, an area of mid-level clouds extends from Molokai to 60 miles east of Maui, and is moving west at around 10 mph. These clouds are thickest from Maui eastward. In addition to the mid clouds, broken low clouds cover northeast sections of Molokai and Lanai. Broken to overcast low clouds cover the interior and northeast sections of the west Maui mountains, and lower slopes of Haleakala from Paia to Hana to kaupo below 5000 ft.
The Big Island is mostly clear. Broken low clouds are located along the eastern slopes of the Kohala range, and along eastern Puna district from Pahoa eastward. An area of overcast showery low and mid level layered clouds is located over the eastern offshore waters, generally from 50 miles east of Hilo to 300 miles east of Hilo. Based on cloud top temperatures, cloud heights extend up to 20000 ft. This area of clouds is moving to the west at 10 mph.
South of the state, isolated cumulonimbus clouds are located generally south of a line from 10°N 162°W to 16°N 145°W to 15°N 140°W. Cloud tops extend up to 48000 ft. Patchy cirrus clouds are also located through this area, generally south of 18°N east of 170°W.

These clouds are located north of a line from 30°N 175°W to 26°N 180°, and are moving to the southeast at 25 mph. An area of towering cumulus and cumulonimbus clouds is located just east of this area, generally north of a line from 30°N 168°W to 27°N 172°W. These clouds are nearly stationary, and cloud tops extend up to 38000 ft.
