    Water vapor images showed an area of low pressure in the middle atmosphere near 30°N just east of the dateline. Towering cumuli and their thin high layered debris clouds formed under this feature within 300 miles of the point 28°N 174°W. Towering cumuli and their thin high layered debris clouds forming within 90 miles of the point 20°N 172°W also may have been associated with the low.

    Otherwise, cloud cover across Hawaiian waters consisted mainly of marine stratocumuli and cumuli. These clouds were greatest in areal coverage within 130 miles of the curve from 25°N 140°W to 21°N 150°W to 21°N 159°W to 16°N 168°W. Individual small cumuli also occurred throughout. These clouds generally moved toward the west southwest at around 15 miles an hour, and rose to heights of 8000 to 10000 feet, though taller cumuli approached 13000 feet.

    To the south, light thunderstorm activity continued in the ITCZ from 13°N to 02°N, chiefly east of 155°W. Layered middle to high debris clouds from this and earlier convection mostly to partly obscured lower features from 14°N to 01°N. Thinner high cloud layers separated from the main part of the ITCZ also partly obscured lower features within 75 miles of the curve from 16°N 155°W to 19°N 152°W to 17°N 146°W.

    Across the main Hawaiian islands, cloud cover consisted about equally of marine stratocumuli and cumuli moving ashore along slopes facing north through east on the one hand, and afternoon cumulus buildups with their layered debris clouds over higher terrain inland on the other. Banding of the clouds over Kauai and Oahu parallel to the mountain ranges on those islands suggested the presence of turbulence in those cloud layers. Areas with the least cloud cover were limited mostly to west Kauai, southwest Oahu, central Molokai, Lanai, west slopes of the west Maui mountains, the central isthmus on Maui, the summit and south slopes of Haleakala on Maui, the west coast of north and south Kohala districts on the Big Island, the west coast of north Kona district on the Big Island, the Kau desert on the Big Island, and interior uplands of the Big Island above elevations of about 6000 feet. These clouds varied in height from 6000 to 10000 feet. Radar data from near the islands showed scattered showers over northeast Maui, offshore to the northeast of Oahu, along the Hamakua coast of the Big Island, and offshore to the east through southeast of the Big Island, but isolated showers at most elsewhere.
