A hydrologic outlook is a type of forecast issued by the National Weather Service to provide information about the potential for flooding or other hydrologic events in a specific area within the next week. It is typically issued for a 30-50% chance of flooding within the next week. The outlook is part of a suite of forecast products that includes outlooks, watches, warnings, and advisories, which are used to convey the severity and timing of a forecast hazard. The Hazardous Weather Outlook (HWO) is another type of forecast that describes potential hazardous weather and hydrologic information of concern in Days 1 through 7. The HWO contains two segments: one segment for the marine zones and adjacent land-based (i.e., coastal) zones and the other segment for the rest of the land-based zones. Each segment of the HWO contains three sections: short term through Day 1, long term for Days 2-7, and spotter information.

In summary, a hydrologic outlook is a type of forecast that provides information about the potential for flooding or other hydrologic events in a specific area within the next week. It is part of a suite of forecast products that includes outlooks, watches, warnings, and advisories, which are used to convey the severity and timing of a forecast hazard.
