Water vapor imagery shows an upper trough with an axis from 24°N 140°W to 25°N 160°W to 10°N 177°W. Southwesterly jet along the southeastern end of tough is carrying cirrus clouds from the ITCZ to the northeast. The high clouds are moving along an axis from 10°N 173°W to 16°N 157°W.
The ITCZ consists of numerous cumulonimbus /cb/ clouds from 04°N to 10°N and 148°W to 174°W. Highest cloud tops reach up to 52 kft. The CB clouds extend east of 148°W, but are contained only between 06°N to 09°N and scattered in coverage.
Elsewhere, an east-northwest to west-southwest oriented stationary front is located along the northwest corner of the central pacifc basin. The front cloud consists of layered clouds between 27°N to 33°N and west of 166°W.
Broken to scattered stratocumulus clouds cover a large area north and east of 154°W. These clouds are traveling east to west at 15 to 25 mph, faster movements to the south. To the west 154°W, the low cloud cover becomes scattered in coverage, consisting of cumulus clouds.
Across the main Hawaiian islands, Kauai has broken low clouds across the windward slopes and leeward coast, with breaks occuring elsehwere. On Oahu, broken clouds cover the Koolau mountains, with mostly sunny to partly cloudy skies over the rest of the island. Molokai has broken clouds over the eastern mountains, and scattered clouds elsewhere. On Lanai, broken low clouds cover most of the island interior. On Maui, broken low clouds cover most of the island, except for the Haleakala summit above 7 kft elevation and the central valley. The Big Island is mostly cloudy over most of the lower slopes up to 7 kft, with the exception of over the Kilauea Volcano. The summits and saddle portions of the Big Island are sunny.
