Water vapor imagery shows an upper level trough digging southward with an axis from 16°N 162°W to 28°N 161°W. To the west, an upper low is centered at 17°N 175°E but moving away to the west. A few cirrus clouds along the eastern fringes of the low are located east of the dateline.
Showery cumulus clouds associated with a weakening frontal boundary is located north of 25°N, between 160°W to 174°W. These clouds are being pushed west by the trade winds at around 10 to 15 mph.
Most of the central Pacific is covered with broken stratocumulus clouds which are primarily located east of 157°W, moving westward at 15 mph. West of 157°W, areal coverage is scattered to broken consisting of cumulus and stratocumulus clouds.
Across the main Hawaiian islands, the broken stratocumulus clouds cover the windward waters from Molokai eastward. Scattered clouds cover the waters adjacent to both Kauai and Oahu this morning. Plume clouds are observed west of the Big Island. On Kauai, broken clouds cover the windward half of the island, with mostly sunny skies elsewhere. Oahu is mostly sunny over the area this morning, with a few clouds over the Koolau mountains. Lanai is sunny this morning, while Molokai is sunny with some cloud cover over the far eastern end of the island. Maui has broken low clouds over the windward slopes of the west Maui mountains and Haleakala. The rest of Maui is mostly sunny. The Big Island also has broken clouds over the lower slopes in both Hilo districts, with a few clouds along the leeward coast.
Far south of the islands, deep convection stretches along much of the intertropical convergence zone, or ITCZ. A large cluster of active thunderstorms goes along a 300 mile wide line from 08°N 140°W to 04°N 180°E. Highest cloud tops within this line of thunderstorms is around 55 kft.
