315 AM HST TUE AUG 11 2026
SYNOPSIS FOR HAWAIIAN COASTAL WATERS
HIGH PRESSURE TO THE FAR NORTHEAST WILL SLOWLY DRIFT INTO POSITION
NORTH OF THE HAWAIIAN ISLANDS INTO THE WEEKEND, PRODUCING
MODERATE TO LOCALLY STRONG TRADE WINDS ACROSS THE REGION.
THE WEATHER PATTERN MAY CHANGE SIGNIFICANTLY THIS WEEKEND AS WE
CONTINUE TO WATCH FOR A DEVELOPING TROPICAL CYCLONE CURRENTLY IN
AN AREA ROUGHLY 1,000 NM EAST-SOUTHEAST OF THE HAWAIIAN ISLANDS.
POTENTIAL IMPACTS ARE UNCERTAIN AT THIS TIME, AS THE TROPICAL
CYCLONE HAS NOT YET FORMED AND TRACK GUIDANCE REMAINS HIGHLY
UNCERTAIN AT THIS TIME. MARINE INTERESTS SHOULD BE PREPARED IN
CASE THIS SYSTEM POTENTIALLY TURNS TOWARDS THE HAWAIIAN ISLANDS
AFTER FORMATION POTENTIALLY AS EARLY AS THIS WEEKEND.
