High pressure will also develop and push trade winds over the area. The Kona low will slowly drift northwest and away from the islands through the middle of the week, with a drying trend - again from east to west - expected Wednesday and Thursday. There’s the potential for rainfall totals reaching 10 to 15 inches over the next few days for some areas, with some isolated areas getting 20 to 25 inches. Those winds will also bring bands of deep tropical moisture northward, so expect locally heavy rain and scattered thunderstorms moving in from east to west. The south-southwest winds will become locally strong by Monday. The cool and drier conditions that brought record low temperatures will change rapidly as winds start to come in from the south to southwest, bringing warmer and more humid air by Monday. For now, a flood watch remains posted statewide through Tuesday afternoon. Weather could remain wet into Tuesday and Wednesday. The threat will start Sunday on Hawaii island and Maui County, spreading to Oahu and Kauai County Sunday night and Monday. The islands will be under the threat of significant rainfall and potentially catastrophic flooding as a strong Kona low develops to the northwest of Kauai.
