1.    Introduction. This chapter defines the types and purpose of forecasts, watches, warnings, and other hydrologic products issued by offices of the National Weather Service (NWS). Consistent usage of these terms by all NWS personnel will aid in achieving uniform understanding of each product by all users. Samples of products are contained in this chapter. Instructions are to be rigidly followed for the heading of each release. The content of  the product may be adjusted to fulfill local requirements and conditions.

Timeliness of hydrologic products is of paramount importance in serving the needs of the public, commerce, and industry. It is essential that River Forecast Centers (RFC), Weather Service Forecast Offices (WSFO), and Weather Service Offices (WSO) ensure prompt and accurate releases of the appropriate hydrologic information. It is mandatory that the time of issuance be given on all hydrologic products issued.

2.    Purpose. One purpose of this chapter is to standardize the hydrologic headings for the various products distributed over Automation of Field Operations and Services (AFOS). This chapter covers all products of the Hydrology Program including river and flood, ice jam, recreation, flash flood, outlooks, hydrometeorological (river and rainfall) reports, and miscellaneous river products. It also includes information pertaining to warnings, watches, statements, and forecasts.

3.    Overview of Hydrologic Product Inventory List (PIL). There are three groups of hydrologic products. These are briefly described below.

3.1    Basic Data. Hydrometeorological data are collected from a variety of sources. These sources include: (1) data from cooperative observers, other agencies, etc. which are collected by WSFO/WSOs and manually entered into the AFOS system; (2) data from cooperative observers and Supplementary Aviation Weather Reporting Stations which are automatically collected at WSFO/WSOs and disseminated over AFOS; (3) data from automated gages which are collected at a central location and then distributed to AFOS via the Hydrometeorological Acquisition and Distribution System (HADS); (4) data from automated local mesonets which are collected by microcomputers and then distributed to AFOS.

3.2     Internal Products. Products derived from the basic data by RFCs for distribution within NWS (and to select cooperative users) -- from RFC to HSA offices.

3.3    Public Products. Watches, warnings, statements, forecasts, outlooks, and summaries that are issued to the public.

3.4    Summary of Hydrologic Products. The categories of hydrologic products are listed in the following summary. Most categories are grouped according to their respective composite AFOS PILs; ES0, FF0, FL0, RV0, and RR0. The summary also provides information as to the kind of distribution the product category receives and the frequency of  issuance.

4.    Responsibilities and Coordination Efforts. The responsibility for the AFOS product identifier (CCCNNNxxx) assignment and definition is in the Office of Hydrology (OH), National Weather Service Headquarters (WSH). OH will specifically coordinate this effort with the Office of Meteorology for consistency and with the Systems Integration Division within the Office of   Systems Operations for implementation. OH will maintain a close liaison with regional headquarters to provide national uniformity in the implementation process. Regional headquarters will assure that interregional consistency be coordinated to the maximum extent. The responsibility for the approval of the AFOS product identifier portion of every hydrologic product is with the Data Review Group of the NWS Configuration Management Board. Updates to this chapter will be prepared by OH. Field offices are responsible for the preparation and coordination of information provided to the public and for ensuring its accuracy and consistency.

5.    Hydrologic PIL. This section describes the hydrologic PIL with descriptive information and examples. Each product described identifies which group it falls into: data, internal products, or public products. The sequence of the listing follows the AFOS composite grouping; examples are included. In some cases, more than one example is listed to cover different applications.

5.1    Hydrologic Long-Range Products. Hydrologic products issued under this group will consist Of relatively long-range forecasts for medium or large river basins. They are issued on a periodic basis. This composite group includes:

    a. products issued by RFCs as guidance to WSFOs, WSOs, and select cooperative users and

    b. products issued by WSFOs and WSOs to the public.

Composite Group ES0

NNN   Priority    Description

ESG    5     Extended Flood Guidance

These are INTERNAL products issued by RFCs to WSFOs and WSOs. These products will contain spring snowmelt advisory information, as well as flood potential guidance information, and will normally result in the WSFO issuing an ESF -- Flood Potential Outlook -- as a public product. Samples of ESG products are shown in examples A and B of the appendix.

ESF    5     Flood Potential Outlook

These are PUBLIC products. They are normally the result of an RFC issuing an ESG product and contain information for the public on flood potential, including flood potential from snowmelt. Samples of typical ESF products issued by WSFOs are shown in examples C and D of the appendix.

ESP    4      Extended Streamflow Prediction (includes 30-day river outlook)

These are INTERNAL products issued by RFCs to WSFOs. In most cases, RFCs will also advise cooperative agencies  (Corps of Engineers, U.S. Geological Survey, Soil Conservation Service, etc.) and distribute these products to them. RFCs will communicate seasonal water supply forecasts to the WSFOs for their issuance of an ESS product. A sample of an ESP product is shown in example E of the appendix.

ESS    5     Water Supply Outlook (includes drought information)

These products are PUBLIC. Water Supply Outlooks are issued by WSFOs based upon ESPs. They also are utilized to convey drought information to the public. A sample is shown in example F of the appendix.

These are PUBLIC products issued by WSFOs and WSOs according to WSOM E-20. Ice jam flood warnings are included principally for the Alaska Region. Sample warnings are shown in examples M and N of the appendix.

NOTE: Additional examples of flood/flash flood products are shown in WSOM Chapter E-20.

5.3    Flood Products. All flood products are PUBLIC and provide warning of flooding, update and/or expand information issued previously in a warning, or summarize the flooding event.

An FLW will be issued for specific locations and will provide specific stages whenever flooding is forecast, imminent, or existing. There may be times when it is appropriate to issue a "general" flood warning covering a geographical area. FLW will normally be issued using river forecasts (RVF) prepared by RFCs. Flood statements (FLS) should be issued at periodic intervals during flooding to keep the public informed of the situation until-the stream has returned to within its banks.

Composite    Group     FL0

   NNN    Priority    Description

FLN    5     National Flood Summary

FLS    3     Flood Statement

This is a PUBLIC product issued by WSFOs and WSOs and RFCs with HSA responsibilities. This product is issued to update and expand the information in the flood warning. The flood statement may be used in lieu of a warning if flooding is forecast, imminent, or existing and presents no threat to life or property. The statement should be used to terminate a flood warning. A sample is shown in example P of the appendix.

FLW    1     Flood Warning

This is a PUBLIC product issued by WSFOs, WSOs, and RFCs with HSA responsibilities. A flood warning normally specifies crest information and is issued for specific communities or areas along rivers where flooding has been forecast, imminent, or is in progress. A sample is shown in example Q of the appendix.

5.4    River Products. River products are: river summary, river forecast, miscellaneous river, recreational statement, and river statement.

UPPER MIDWEST SPRING SNOWMELT FLOOD OUTLOOK UPDATE
NORTH CENTRAL RIVER FORECAST CENTER
NATIONAL WEATHER SERVICE MINNEAPOLIS MN
600 PM C.ST THU MAR 21 1985

THIS SPRING SNOWMELT FLOOD OUTLOOK INCLUDES THE FOLLOWING RIVER BASINS...THE SOURIS...RED RIVER OF THE NORTH...MISSISSIPPI RIVER BASIN TO CHESTER ILLINOIS...AND TRIBUTARIES OF THE UPPER GREAT LAKES.

RUNOFF FROM SNOWMELT COMBINED WITH RAIN DURING MID-MARCH HAS BROUGHT RIVERS ABOVE FLOOD STAGE LEVELS IN LOWER MICHIGAN...NORTHERN INDIANA...ILLINOIS... IOWA. ..SOUTHERN WISCONSIN. ..AND MISSOURI.

A SNOW COVER REMAINS OVER PARTS OF THE UPPER MIDWEST...INCLUDING NORTH DAKOTA...MINNESOTA EXCEPT THE SOUTHWEST AREA...CENTRAL AND NORTHERN WISCONSIN...NORTHEAST IOWA...MICHIGAN UPPER PENINSULA...AND NORTHERN LOWER MICHIGAN.

THE POTENTIAL FOR SNOWMELT FLOODING REMAINS IN THOSE AREAS DESCRIBED ABOVE. WET SOILS...SOME FROZEN SOILS...HIGH WATER CONTENT OF SNOW...AND MODERATE TO HEAVY RIVER ICE SIGNIFY THE EXISTING POTENTIAL FOR FLOODING.

THE NATIONAL WEATHER SERVICE SPRING SNOWMELT FLOOD OUTLOOK WHICH WAS RELEASED ON MARCH 7 1985 IS STILL VALID FOR THE AREA DESCRIBED ABOVE.

THE OUTLOOK...BASED ON CURRENT CONDITIONS AND ASSUMED NORMAL Precipitation AND TEMPERATURE PATTERNS THROUGH THE COMING MELT PERIOD IS FOR MINOR TO MODERATE FLOODING ALONG RIVERS AS INDICATED IN SPECIFIC ESC PRODUCTS FOR EACH STATE.

SPRING SNOWMELT FLOOD POTENTIAL OUTLOOK FOR MICHIGAN PART 1 OF 2 NATIONAL WEATHER SERVICE ANN ARBOR MI 730 AM EST FRI MAR 2 1984

THE COMBINED EFFECTS OF THE HEAVY SNOW...RIVER ICE...AND FROZEN SOILS HAVE CREATED A POTENTIAL FOR SPRING FLOODING IN MICHIGAN.

MINOR TO MAJOR FLOODING MAY OCCUR IF PRECIPITATION IS NORMAL OVER THE NEXT SEVERAL WEEKS...AND A NORMAL MELT OCCURS. THE MAGNITUDE OF THE FLOODING WILL depend GREATLY ON WEATHER CONDITIONS FOR THE NEXT SEVERAL WEEKS.

ABOVE FREEZING TEMPERATURES DURING FEBRUARY AND EARLY MARCH COMPACTED THE SNOW COVER BUT THE WATER CONTENT OF THE SNOW IS HIGH. THE STORM YESTERDAY ADDED 0.50 INCH TO 0.75 INCH OF WATER CONTENT TO THE SNOWCAP. WATER EQUIVALENTS FROM NEAR 2 TO OVER 7 INCHES HAVE BEEN REPORTED. MOST SOILS REMAIN FROZEN NEAR THE SURFACE.

THE SPRING SNOWMELT FLOOD POTENTIAL OUTLOOK IS FOR MODERATE TO MAJOR FLOODING ALONG THE RIVERS IN SOUTHEAST MICHIGAN. THIS INCLUDES THE ROUGE...CLINTON ...RAISIN...AND HURON RIVER BASINS.

THE OTHER RIVERS IN MICHIGAN HAVE AN OUTLOOK OF MINOR TO MODERATE FLOODING. THIS INCLUDES THE ST. JOSEPH...KALAMAZOO...GRAND...SAGINAW...MUSKEGON...AND WHITE RIVER BASINS.

THE SPRING SNOWMELT FLOOD OUTLOOK IS BASED ON A Knowledge OF EXISTING HYDROLOGIC CONDITIONS AND AN ASSUMED NORMAL PRECIPITATION AND MELT PATTERN THROUGH THE EXPECTED MELT PERIOD.

A RAPID MELT WITH ABOVE NORMAL PRECIPITATION WOULD INCREASE THE FLOOD THREAT. BELOW NORMAL PRECIPITATION AND A SLOW MELT PATTERN WITH INTERMITTENT FREEZING AND THAWING WOULD RESULT IN REDUCED FLOODING.

FLOODING MAY ALSO OCCUR DUE TO ICE JAMS. RIVER INTERESTS SHOULD BE ALERT TO C.HANGING. ICE CONDITIONS AS RUNOFF BEGINS.

MINOR FLOODING...A GENERAL TERM INDICATING MINIMAL OR NO PROPERTY DAMAGE BUT POSSIBLY SOME PUBLIC INCONVENIENCE.

MODERATE FLOODING...THE INUNDATION OF SECONDARY ROADS...TRANSFER TO HIGHER ELEVATION NECESSARY TO SAVE PROPERTY. SOME EVACUATION MAY BE NECESSARY.

MAJOR FLOODING...A GENERAL TERM INDICATING EXTENSIVE INUNDATION AND PROPERTY DAMAGE.

A NUMERICAL SPRING SNOWMELT CREST OUTLOOK FOR THE RIVERS OF MICHIGAN FOLLOWS. IT CONTAINS TWO SETS OF SNOWMELT OUTLOOK CREST VALUES. THE FIRST SET IS FOR A NORMAL MELT OF THE SNOW WITH NO ADDITIONAL PRECIPITATION. THE SECOND SET CONTAINS THE OUTLOOK CREST VALUES WITH THE ASSUMPTION OF NORMAL ADDITIONAL PRECIPITATION AND MELT PATTERNS FROM NOW THROUGH THE COMING MELT. IN THE TABLE... FIRST SET /1/ PRESENT WATER EQUIVALENT W.E.

SECOND SET /2/ W.E. PLUS NORMAL PRECIPITATION

REFERENCE MUST BE MADE TO THE ASSUMPTIONS DISCUSSED PREVIOUSLY IN THIS OUTLOOK WHEN USING THE CREST OUTLOOKS IN THE TABLE.

RIVER INTERESTS SHOULD BE ALERT FOR POSSIBLE RAPID CHANGES DUE TO ICE JAMS WITH THE MODERATE TO HEAVY ICE EXISTING ALONG MANY RIVERS. THE NUMERICAL CREST OUTLOOKS DO NOT REFLECT AGGRAVATED FLOODING FROM POTENTIAL ICE JAMS.

SUMMARY... IN GENERAL...CONDITIONS HAVE CHANGED LITTLE SINCE LAST WEEK. LOCK 20 ON THE MISSISSIPPI WAS CLOSED ON JANUARY 13 FOR APPROXIMATELY 30 DAYS FOR DEWATERING. ON THE ILLINOIS...GENERATED WARM WATER IN THE UPPER REACHES CONTINUES TO KEEP THE RIVER PARTIALLY TO MOSTLY OPEN WITH ONLY THIN ICE FROM LOCKPORT DOWN TO MARSEILLES...WHILE IN CONTRAST STARVED ROCK AND PEORIA REPORT 10-14 INCHES OF ICE.

FORECAST... RELATIVELY MILD TEMPERATURES ARE EXPECTED THIS WEEK...GENERALLY RUNNING 10 DEGREES ABOVE NORMAL...CONSEQUENTLY WE EXPECT LITTLE IF ANY NEW ICE DEVELOPMENT. HOWEVER...RUNNING AND BREAKING ICE MAY CAUSE SOME ICE JAM PROBLEMS IN THE SOUTH BELOW DAM 20 ON THE MISSISSIPPI AND BELOW PEORIA ON THE ILLINOIS.

THE LAmanual NATIONAL WEATHER SERVICE 30-DAY OUTLOOK CALLS FOR EQUAL CHANCES OF TEMPERATURES BEING ABOVE OR BELOW NORMAL FOR THE PERIOD MID-JANUARY TO MID-FEBRUARY.

NATIONAL WEATHER SERVICE ASHEVILLE, NC
934 AM EDT THU AUG 25 1988

TO: ALL USERS OF RIVER DATA FROM ASHEVILLE, NC

FROM: WSO ASHEVILLE, NC.

THIS OFFICE WAS NOTIFIED LAST EVENING BY THE USGS IN ASHEVILLE, THAT THE DATA FROM AVLN7 (FRENCH BROAD RIVER GAGE IN ASHEVILLE) IS NOT A GOOD REPRESENTATION OF THE RIVER LEVEL.

THIS IS DUE TO A TEMPORARY DAM THAT HAS BEEN CONSTRUCTED ABOUT A QUARTER MILE UPSTREAM FROM THE GAGE. THE DAM IS TO RESTRICT RIVER FLOW UNTIL A SEWER LINE CAN BE BURIED UNDER THE RIVER.

THIS CONDITION WILL LAST FOR ABOUT THE NEXT 3-4 MONTHS. USGS IS WATCHING THIS PROJECT CLOSELY AND WILL INFORM THE WSO IN ASHEVILLE WHEN RIVER FLOW AND READINGS ARE ACCURATE.
