    Water vapor imagery shows an upper level low near 31°N 175°W, or about 250 miles northeast of Midway atoll. This low is moving northeast at less than 10 mph. Scattered cumulonimbus clouds are located within 400 miles east of the low and within 300 miles south of the low. Cloud tops in this area extend up to 45000 ft.

    Additional cumulonimbus clouds are located farther south, generally within the area from 24°N 173°W to 10°N 168°W to 15°N 177°W. Cloud tops in this area extend as high as 54000 ft. Additional mid and high level layered clouds extend farther north and east of these convective clouds, generally north of 17°N between 161°W and 174°W.

    Another area of cumulonimbus clouds is associated with a surface trough south of the state. These clouds are scattered in coverage, and located within 300 miles east of a line from 14°N 165°W to 10°N 161°W. Cloud tops extend up to 54000 ft. Additional isolated cumulonimbus clouds are located along a line from 13°N 157°W to 10°N 149°W. Cloud tops in this area extend up to 45000 ft.

    Isolated cumulonimbus clouds are also located with the remnant low that was former tropical depression Eight-E. These clouds are located generally from 13°N to 18°N between 144°W and 147°W. Cloud tops in this area extend up to 50000 ft. Broken to overcast low and mid level clouds are located just north of this area, generally east of a line from 25°N 143°W to 20°N 150°W.

    Across the main Hawaiian islands, broken low clouds cover interior and eastern sections of Kauai, and also much of Oahu. Broken to overcast low clouds cover the northeast half of Molokai and the interior of the west Maui mountains. Broken to overcast low clouds also cover the windward slopes of Haleakala from nahiku to Hana to Kipahulu below 4000 ft.

    On the Big Island, broken to overcast low clouds cover the windward slopes of the Kohala range. Broken low and mid level clouds cover portions of north and south Hilo and Puna districts below 7000 ft. Patches of broken low clouds extend up to 100 miles offshore to the northeast. Broken to overcast low clouds cover Kau district below 4000 ft from Pahala westward. Broken low clouds also cover south Kona district below 4000 ft, and extend over 100 miles offshore to the west-southwest.
