The primary concern for Hawaii is the significant wave action expected to impact its eastern shores. Waves of up to 15 feet pose a considerable risk to swimmers, surfers, and boaters, increasing the likelihood of dangerous rip currents. These powerful currents can quickly pull even strong swimmers out to sea, making them a serious threat to water safety. Coastal communities and infrastructure may also be vulnerable to increased surf and potential erosion. Authorities are advising residents and visitors to exercise extreme caution when near the ocean, particularly on beaches facing the storm's direction. The elevated swells will persist through Wednesday, necessitating ongoing vigilance for anyone planning to engage in marine activities or spending time along the coast.
