Hurricane Lowell poses the greatest risk due to its proximity to Hawaii, with large swells already affecting the islands, creating life-threatening surf and rip currents. Hurricane Karina remains over open waters, posing no immediate threat to land, while Hurricane Marie is generating dangerous surf along Mexico's southwestern coast and Baja California Peninsula. Swells from Marie are expected to reach Southern California this weekend, potentially causing hazardous beach conditions. Residents in affected areas should remain vigilant and monitor local advisories.
