SYNOPSIS

AUG 21 2017 11:21:00 HST
AUG 22 2017 07:21:00 UTC

Synopsis for Hawaiian coastal waters:
A weak cold front far to the north has weakened the subtropical ridge of high pressure. As the front moves east, high pressure will rebuild north of the area on Tuesday and strengthen the trade winds. An upper level low will produce unstable conditions over the western waters through Tuesday.
