Low clouds have increased across windward sections of the main Hawaiian islands during the night as moderate trade winds continue. Areas of broken stratocumulus and cumulus are present over windward areas of Kauai, Oahu, Molokai, Maui and the Big Island. Scattered low clouds are spilling over into some leeward areas as well. Across the coastal waters around Hawaii, cloud motions are to the west at 20 to 25 mph, and have accelerated since Thursday evenings. The highest cloud tops around the state are estimated to be near 9 thousand feet.
Over the far northwestern Hawaiian islands, a 400 mile wide band of broken to overcast low and mid level cloudiness, associated with a cold front, lies north and west of a line from 30°N 168°W to 22°N 180. This band of clouds is moving to the east at 30 mph north of 25°N, but is drifting very slowly eastward south of 25°N. Highest cloud tops in this band are estimated near 15 thousand feet.
The layered cloudiness associated with a weak cold front far to the northeast of Hawaii has now moved east of 140°W and out of the discussion area. There is no longer an identifiable cloud feature along the remnants of the old front northeast of Hawaii between 140°W and 150°W. Remnants of a dissipated front south of the Big Island have also degenerated to the point that there is no longer an identifiable cloud feature present.
Otherwise across the tropical central north Pacific from 10°N to 30°N between 140°W and the date line, scattered to locally broken stratocumulus are predominant, with no significant deep convection noted. Far to the south, clusters of deep convection associated with the intertropical convergence zone remain south of 5°N between 153°W and 180, although some cirrus cloudiness emanating from this convection is spreading northward into the discussion area between 160°W and 180 and south of 13°N.
