Tropical Storm Gilma, currently with maximum sustained winds of 40-45 mph, is expected to weaken and dissipate near Kauai by Saturday, according to the National Hurricane Center. The storm will bring rain to the Hawaiian Islands, with the heaviest rainfall occurring if Gilma shifts south. Tropical Storm Hector, following closely behind Gilma, is also expected to weaken and bring moderate rain but no significant impacts. High pressure and trade winds will continue to influence weather patterns, leading to sporadic showers, especially in windward regions. Residents are advised to prepare for wet conditions but not severe weather impacts.
