REMAINDER OF THE AREA A 1006 mb low is near 23N139W which is a little more than 1000 miles east-northeast of Hilo, Hawaii. Strong winds are noted north of the low with seas 12 to 17 ft. Showers and thunderstorms around this low have decreased and become less organized, and is noted east of the low from 13N to 25N between 126W and 133W. This system is expected to move westward into increasingly unfavorable environmental conditions during the next day or so, and development into a subtropical or tropical cyclone is unlikely.

As the low moves west of 140W later today, it will substantially weaken. Winds and seas are expected to diminish this afternoon through tonight. $$ AReinhart
