Residents of Kauai and Niihau are under a tropical storm warning, with potential impacts including strong winds, heavy rainfall, and dangerous surf conditions. Swells generated by Hurricane Lowell are expected to cause life-threatening rip currents along the Hawaiian coastlines. Additionally, Hurricane Marie is producing hazardous surf conditions along Baja California and Southern California. While Tropical Storm Karina poses no direct threat to land, its remnants may still influence weather patterns in the region.
