boaters using these harbors urged to exercise extra caution today
and tonight as a large northeast swell reaches the islands north 
and east facing shores. the swell with a long period 13 to 14 
seconds, coupled with the size of the swell of 10 to 11 feet, is 
likely to produce moderate to strong surges in harbors such as 
hilo and kahului today and tonight. large waves break at harbor 
entrances and channels will pose a threat to vessels entering or 
exiting the harbors. the northeast swell will begin to diminish 
tonight and continue through friday.
