  A Hazardous Seas Watch is issued by the National Weather Service of the United States when there is an increased threat of high wave heights and/or wave steepness values reach a certain criteria, but the occurrence, timing, and/or location are still uncertain, though the area of concern is known. The criteria are set by the local forecast offices. It is normally accompanied with strong winds, and occasionally even cyclonic activity. Such tall waves can pose a serious threat to vessels that do not seek shelter, as well as vehicles and property very close to concerned waters.
