Hurricane conditions, including winds of up to 75 mph, are possible on Hawaii Island by early Saturday. Heavy rainfall may lead to life-threatening flooding and mudslides, especially in steep terrain. Coastal areas could experience localized flooding and significant beach erosion due to storm surge and high tides. Dangerous surf and rip currents are expected to affect east-facing shores starting Friday and intensify through the weekend. Elevated wildfire risks are also anticipated due to strengthening winds and dry air conditions.
