| 7- Day Evapotranspiration Forecast | The 7-day evapotranspiration forecast displays graphically on the Internet the expected amount of evapotranspiration in hundredths of an inch for each of the next 7 days using a reference crop of alfalfa. A second graphic is provided for each day that indicates whether the evapotranspiration is expected to be above or below normal. This product will be issued daily at 5 am local time on a seasonal basis (March 15-October 15). | evappdd.pdf |
| ABRFC Recreational Forecast Graphics | The National Weather Service (NWS) is the agency responsible for issuing river forecasts and flood warnings for the United States. This information is provided in order to protect life and property as well as to enhance the national economy. In cooperation with national, state and local agencies, as well as private organizations and the public, the NWS determines the river levels which correspond to the beginning of significant damage from high water. This level of water at a given river location is termed flood stage. The NWS issues special river forecasts and flood warnings when levels are expected to equal or exceed flood stage. In addition to problems caused by flooding, various users have danger and incur risk due to river fluctuations and river levels lower than flood stage. Examples of these types of users of river forecast information include navigation interests or the general public who use the river and river banks for recreational purposes. The experimental Recreational Forecast graphics are Internet web pages that depict the expected river levels for the Illinois River of Oklahoma, a very popular canoe and raft float stream. These expected stream flow levels are translated to a river floatability index based on guidelines provided by the Illinois River Association and the State of Oklahoma Scenic Rivers Commission. Recreational interests can use the information to better insure a safe experience on and near the river. | SR-9.pdf |
| ADVANCED HYDROLOGIC PREDICTION SERVICE (AHPS) FLOOD INUNDATION MAP INTERFACE | The NWS River Forecast Centers produce river stage forecasts for more than three thousand locations in the U.S. These forecasts reference numeric gage heights at a single site along the river, generally in or near a city. Flood inundation maps are available for specific NWS forecast points where a flood inundation library has been developed through a partnership with Federal, state, and/or local agencies.
Flood Inundation Maps show the extent of flooding expected spatially over a given area. This will indicate where roadways, streets, buildings, airports, etc., are likely to be impacted by floodwaters. Combined with river observations and NWS river forecasts, inundation maps provide decision-makers additional information needed to better mitigate the impacts of flooding and build more resilient communities.

| Air Quality Index (AQI) | The Air Quality Index (AQI)), also know as Clearing Index and Ventilation Index is both a text and graphical product produced by forecasters in support of the Fire Weather Program. The AQI has been used for many years by health and land management officials to help determine pollution and smoke dispersion on any given day. AQI numbers range from 0 (no dispersion) to 1000+ (excellent dispersion). When used as a Ventilation Index, values range from 0 to 100,000 | AirQuailityIndexPDD.pdf |
| Airman's Meteorological Advisories (AIRMET) | AIRMETs are concise descriptions in abbreviated language of the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena issued by the National Weather Services Aviation Weather Center, Alaskan Aviation Weather Unit, and Weather Forecast Office Honolulu. AIRMET phenomena can affect the safety of aircraft operations. Bulletins contain details of potentially hazardous conditions over the continental United States, Alaska, Hawaii, and adjacent waters. An AIRMET will be issued when any of the following weather phenomena occur and affect an area of at least 3,000 square miles:
Moderate icing,
Moderate turbulence,
Sustained surface wind of 30 knots or more,
Ceilings less than 1,000 feet and/or visibility less than miles affecting over 50 percent of an area at any one time or,
Extensive mountain obscuration (may be less than 3000 square miles for Pacific Ocean islands).
