Trade winds will decrease and the chance of showers will increase to start the week as a disturbance aloft combines with incoming moisture from former tropical cyclone Ulika. Heavy showers are due to develop Monday and Monday night, mainly for windward areas, with the highest chance for the heavy rain over Maui and the Big Island.
Winds are expected to become rather light by Tuesday, with humid and hazy conditions along with the chance of showers and downpours, especially during the afternoons. Drier and more stable conditions should return by Thursday or Friday.
A Small Craft Advisory is in effect until 6 a.m. Monday for waters around Kauai and Oahu, and 6 p.m. Monday for waters around Maui County and the Big Island. The current breezy trades are still bringing in a choppy east swell, while other shores will remain pretty small for most of the week. We could get a swell near advisory levels for north shores this coming weekend.
