Tropical Storm Greg will pass well to the south of Hawaii today,
and besides some locally gusty winds, should not pose a threat to
Hawaii. After this, winds should relax a bit as upper level
ridging builds over Hawaii with mostly dry weather. Around
Sunday/Monday, the guidance continues to show the remnants of what
is now Tropical Storm Fernanda in the east Pacific sliding just to
the south of the Big Island. This would bring an uptick in
moisture and gusty winds across the state, favoring Maui and the
Big Island, with some increasing threat for moderate to heavy
rains. There is still plenty of uncertainty remaining on exact
rainfall amounts/impacts. A more typical trade wind pattern should
return after next Wednesday.
