Ample moisture remains over the area thanks to a surface trough (the remains of a front) and an upper level low to our west- southwest. This upper low will weaken and slowly drift farther to the southwest and away from the state through Wednesday. A surface high to our north will strengthen overnight, helping keep strong trade winds blowing through tomorrow, with only a little bit of weakening going into Tuesday. The potential for flooding will remain over all islands tonight and Monday, with the highest chance over windward Maui County and windward Big Island. Strong winds will continue to occur over all islands as well, with the strongest winds in the lee of mountains and in/near stronger showers. There is still a slight chance of thunderstorms through Monday. After Tuesday, trades will maintain above-normal strength, and windward showers will be plentiful, but the high threat potential of today through Monday will end.
