Waipahu is a large community in central Oahu's Ewa Plain near Pearl Harbor, with tsunami risk from Pacific seismic events and hurricane exposure. Its proximity to Pearl Harbor places it in awareness of military infrastructure considerations. Flooding from Waikele Stream during intense rainfall is a localized hazard, and the low-lying Ewa Plain is vulnerable to inundation from major coastal storm events.
