Residents and visitors on Maui and the Big Island should prepare for wet conditions, particularly in windward and higher elevation areas. Isolated thunderstorms on the Big Island could bring localized heavy rainfall and gusty winds. Coastal areas on north and west-facing shores are under a High Surf Advisory until 6 p.m. today, with potentially hazardous surf conditions. East-facing shores will also experience rough and choppy waters due to strong trade winds. Travelers and outdoor enthusiasts should exercise caution in these areas.
