Although low cloud ceilings have been occasionally occurring in windward and mauka sections on the individual isles, skies are predominantly clear to partly cloudy across the aloha state and coastal waters this early morning. Low cloud movement is from the east to east-northeast between 15 and 20 mph over the entire island chain as of bulletin time.
The portion of a front north of the isles has been weakening, possibly dissipating, since last evening. The front east of 150°W, whose southern boundary is currently along a line from 22.5°N 140°W to 20.5°N 150°W, has been maintaining its essential structure for the time being. The segment west of 150°W has been losing most of its cloudiness. At the moment, lower clouds that remain are north of a line from 20.5°N 150°W to 23.5°N 155°W to 26°N 158.5°W. The boundary has been heading south to southwest between 10 and 15 mph.
As of this writing, hurricane Ana is about 825 miles north- northwest of Kauai and continues to move northeast near 25 mph. Convection with the system is mainly located from 32°N to 34°N between 163°W and 166°W. Farther afield, a weak front is southwest from Ana, and isolated thunderstorms associated with the feature are found within 120 miles either side of a line from 29°N 169°W to 25°N 175°W to 21°N 178.5°E.
Showers and thunderstorms are firing far south of Hawaii along the intertropical convergence zone. The most intense cells are igniting from 07°N to 12°N east of 142°W, and from 03.5°N to 09°N west of 163°W. Some of the convective elements are rising to over 50 thousand feet.
