The weather is forecast to remain hot and humid through the week.
The heat index for Honolulu, which factors in air temperature and humidity to reflect what it really feels like outdoors, is expected to hit 95 degrees Fahrenheit this afternoon.
A flood advisory was posted for Kauai County this morning after radar showed heavy rain near Poipu and Lihue falling at up to 1 inch per hour. The advisory is in effect through 8:30 a.m.
A flash flood watch, meanwhile, remains in effect for Niihau and Kauai through this afternoon due to deep tropical moisture ahead of an approaching low-pressure trough that will raise the potential for heavy rainfall, thunderstorms and flash flooding.
During the next few days, low pressure northwest of Kauai will lift northeast, dragging a trough slowly eastward toward the islands, weather officials said, and bringing muggy conditions across the isles through most of the week.
A more typical trade wind pattern should return by Thursday night or Friday, with breezy trades returning for the weekend.
