Humid conditions are sticking around and the chance of heavy showers is lingering through Friday with flash flooding possible for much of the state. Weak trade winds should begin to fill in Friday with moderate trades expected Saturday. Showers are expected to favor windward and mauka areas, afternoon clouds and spotty showers can be expected over leeward areas. Forecast uncertainty increases significantly on Monday and Tuesday, hinging on the eventual track of hurricane Ignacio. Hurricane Ignacio will approach the Big Island late in the weekend and may threaten the islands early next week. Forecast track errors at that time are more than a couple hundred miles, so it is too early to tell what the direct impacts will be.
Today we expect mostly sunny skies in the morning becoming mostly cloudy in the afternoon. Scattered showers are expected in windward spots with scattered afternoon showers for leeward spots. Hazy skies are also forecasted for the Kona side (see UHSOEST vog map above). High temperatures from 83° to 88°. Trade winds from 5 to 15 mph are forecasted.
