During a red-flag warning, residents are urged to avoid risky behavior like campfires or other open flames, smoking or setting off fireworks. The NWS also urges residents to have an evacuation plan, ensure they have a go kit ready in case of an emergency and listen to their local officials for evacuation updates.

The red flag warning for Hawaii has been extended into a fourth day, as high winds, low humidity and an abundance of dry brush combine to make portions of all islands vulnerable to fast-moving wild fires.

The National Weather Service has extended the state's Red Flag Warning for the second time, this time set to expire on Aug. 3 at 6 p.m.
