Overcast layered clouds cover a broad area of the north Pacific in an area bounded by 27°N 157°W 19°N 150°W 10°N 161°W 17°N 171°W 27°N 157°W. Isolated cumulonimbus, CB, are embedded in this area south of a line from 23°N 150°W to 13°N 166°W. This area of layered clouds covers all of the main Hawaiian islands, while the CB area lies just southeast of the islands. These clouds merge with those associated with scattered CB south of 10°N marking the intertropical convergence zone. Almost obscured by the layered clouds is a deep low centered near 28°N 153°W, about 560 miles northeast of the Hawaiian islands. Overcast layered clouds marking the northeast flank of this low extend north beyond 40°N between 145°W and 155°W. Isolated embedded CB persist within 120 miles north through east of the low.
A broad anticyclonic circulation is noted northwest of the layered clouds, centered near 38°N 176°W. Another anticyclonic circulation is noted near 40°N 138°W, just east of the layered clouds. While the islands are covered by layered clouds, southeast flow noted east of 150°W and northeast flow west of 160°W between 10°N and 30°N implies a surface trough exists over or near the islands.
