Tropical storm Ana is located about 440 miles west of Lihue at 2 pm HST, and is moving to the northwest at 8 mph. A small but intense area of cumulonimbus clouds is located between 40 miles and 150 miles north of Ana, with cloud tops extending up to 50000 ft. Additional isolated cumulonimbus clouds are located between 200 miles and 400 miles northeast of Ana, and between 162°W and 164°W north of 18°N. Cloud tops in these areas extend up to 45000 ft. Addition cirrus and cirrocumulus clouds are located within 500 miles northwest through northeast of Ana.

Additional isolated cumulonimbus clouds are located farther west, from 25°N to 28°N between 173°W and 176°W, and from 18°N to 22°N W of 178°W. Isolated towering cumulus clouds are located elsewhere through this same area, generally west of a line from 30°N 171°W to 19°N 175°W to 18°N 180°. These cloud tops extend up to 25000 ft. Additional cumulonimbus clouds are located south of a line from 11°N 180° to 16°N 164°W to 11°N 150°W, with cloud tops extending up to 40000 ft.

Across the main Hawaiian islands, scattered to broken high clouds cover portions of Kauai and Niihau, but low clouds are still visible. Broken low clouds cover the eastern slopes and western coastal sections of Kauai. Broken to overcast low clouds cover the slopes of both the Koolau and Waianae ranges on Oahu, with only scattered clouds in between. Low clouds extend 30 miles offshore to the west and northwest from the Waianae coast. Broken to overcast low clouds cover the interior of Molokai, and extend 20 miles offshore to the west. Broken to overcast low clouds also cover the interior of Lanai and the west Maui mountains. Broken to overcast low clouds cover the lower slopes of Haleakala from Ulupalakua to keanae below 6000 ft, with scattered to broken low clouds across the remaining slopes.

On the Big Island, broken low clouds cover much of north and south Kohala districts and Hamakua district below 9000 ft, with leeward coastal sections mostly clear. Scattered to broken low clouds are located over interior sections of north and south Hilo districts, generally between 2000 ft and 7000 ft. Broken to overcast low clouds cover Kau district between 2000 ft and 10000 ft, as well as most of north and south Kona districts. Scattered to broken clouds also are located over the upper slopes of Mauna Kea and Mauna Loa extending up to 13000 ft.

North of the state, a band of showery cumulus clouds up to 100 miles wide is located south of a line from 25°N 160°W to 23°N 150°W to 22°N 140°W. Individual cloud elements are moving to the west-northwest at 15 mph, while the overall band has been nearly stationary.
