the risk of a hazardous weather or hydrologic event has increased significantly,
but its occurrence, location and/or timing is still uncertain. It is intended to

so. Watches evolve into warnings, advisories, or they are canceled.
Warning These products are
issued when a hazardous weather or hydrologic event is occurring, is imminent,

voice when issuing warnings for life-threatening situations.
