7- Day Evapotranspiration ForecastThe 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 GraphicsThe 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
Addition of Waterspout coding to the Special Marine Warning and Marine Weather Statement for all CONUS Coastal WFOS., WFO Honolulu and GuamNWS Central Region offices have issued Special Marine Warnings (SMW) and Marine Weather Statements (MWS) with tags for hail and wind as an operational product format since 2010. The purpose of this PDD is to change how these hail and wind tags are encoded to bring them into conformity with how they are done within the Severe Thunderstorm Warning product, and to introduce a new tag to help users better identify the potential threat from waterspouts for all coastal WFOs PDDSMWWaterspoutTags2017.pdf
ADVANCED HYDROLOGIC PREDICTION SERVICE (AHPS) FLOOD INUNDATION MAP INTERFACEThe 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. floodinundationgraphicpddupdate101707vth2.pdf
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
