HONOLULU (HawaiiNewsNow) -

Showers and humidity are forecast to increase throughout Monday as a trough moves through the state.

The trough is what's left of former tropical cyclone Fausto. Showers began increasing by midday Sunday on the Big Island of Hawaii, where there is a slight chance of thunderstorms through Monday. In fact forecasters say that Hilo broke a record for daily rainfall, and 24-hour accumulation at several sites exceeded four inches.

The trough expected to move over the island chain Monday and Tuesday, bringing an increase in showers, mainly for windward areas and southeast slopes. Some showers could spill over into leeward areas. It will also bring muggier conditions.

The forecast calls for the system to weaken as it continues westward. It should clear the state by Tuesday or Wednesday, bringing more normal trade wind weather conditions.

Trade winds will be backing off a bit through Monday, but are forecast to increase Tuesday and Wednesday. Forecasters also say that another system approaching from the east, "may bring another period of unsettled weather by the weekend."
