Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
256 AM EDT Sat Aug 2 2025

Valid 00Z Sun 03 Aug 2025 - 00Z Sun 10 Aug 2025

Hawaii has been situated in between a surface high pressure
system to the north and multiple tropical lows including Iona and
the remnants of Keli that passed south of the state. This pattern
offered a tight pressure gradient to yield breezy to locally
strong easterly island trades. Moisture has been limited, while
the inversion aloft stay low under an upper ridge, leading to only
a few passing showers. However with tropical system passage and
demise, island winds will ease to more moderate to breezy levels
over the weekend into next week. By mid-later next week though,
will continue to monitor potential for any energy and/or wrapping
moisture from current east-Pacific Hurricane Tropical Storm Gil
forecast that is forecast to track to the northeast of the state.
