HONOLULU (HawaiiNewsNow) – The Hawaii News Now weather team has forecast Friday First weather warning day while Gilma approaches the state bringing more rain along with light winds and higher humidity to most parts of the state.
The effects will not be destructive, but rather disruptive.
Current forecasts predict that Gilma will continue to weaken as a tropical depression as it moves west-northwest along the island chain.
At this time, the strongest winds are expected to still be blowing over the eastern coastal/offshore waters and the winds along the land areas and leeward coastal waters will even weaken from Friday to Saturday and take on a more southeasterly component.

These weaker winds can cause showers to extend to the leeward parts of the state, as sea breezes increase there and move more moisture around the island area.
The heaviest rainfall is expected to fall during the night from Thursday to Saturday. Over the mountains it may rain heavier at times.
Although widespread flooding is not expected given the currently forecast rainfall of 2.5 to 7.5 centimetres, local flooding is possible.
Aside from the chance of rain, the moisture that will come in as Gilma passes nearby will raise the dew point temperature by a few degrees, making it feel a bit muggy over the weekend.
If the system is further north, that means less rain and more humidity for us. If it hangs out further south, closer to the islands, that probably means more rain.
Gilma is expected to weaken to a remnant low overnight Thursday into Sunday and dissipate near Kauai on Saturday.
Not far behind Gilma was Tropical Storm Hector, which has since dissipated. What remains of it is expected to move westward and should be a weak surface trough that could bring a slight increase in rainfall and more humid weather sometime Saturday night.
