Valid 00Z Fri 01 Aug 2025 - 00Z Fri 08 Aug 2025

For the next several days, Hawaii will be located in between a
surface high pressure system to the north and multiple tropical
lows -- Tropical Storm Iona, the remnants of Keli, and another
tropical disturbance being monitored for development -- all
passing south of the state. This pattern will continue a tight
pressure gradient and yield breezy to locally strong easterly
trades. Moisture should be limited, while the inversion aloft
should stay low under an upper ridge, leading to only a few
passing showers. Winds may ease a bit to more moderate to breezy
levels early next week, but other than that there does not appear
to be much change to the pattern in the next several days. By the
middle of next week though, will continue to monitor potential for
any lingering remnant energy from another tropical system that
could approach Hawaii from the east, which would increase
moisture.
