Product Name Brief Description Operational Date
Sierra Backcountry Forecast The Sierra Backcountry Forecast is a web based text product produced by forecasters in support of the Sierra Avalanche Center and the Central Sierra Avalanche Center. The product provides forecasted parameters critical to accurately forecasting avalanche conditions by the Sierra Avalanche Centers. The elements forecasted include temperatures, winds, and sky/weather, all of which affect the stability of the snowpack, changes in the snowpack structure, and ultimately avalanche potential. 2007-11-29 
WFO Eureka Humboldt Bay Bar Graphical Forecast A graphical display of wave height, period, direction and areas of extreme wave steepness or breaking potential in and near the entrance to Humboldt Bay, CA 2007-11-27 
NATIONAL MULTI-SENSOR PRECIPITATION ESTIMATES WEB-BASED SERVICE These Quantitative Precipitation Estimates (QPE) Graphics are representations of rainfall that has occurred for a specific length of time. Currently, each RFC prepares its QPE graphics using different colors, precipitation thresholds, and geographic projections. By producing these graphics centrally, it will enable the public to compare data across the CONUS and Puerto Rico. Parameter-Elevation Regressions on Independent Slopes Model (PRISM) climate data from a cooperative venture between Oregon State University and the United States Department of Agriculture-Natural Resources Conservation Service provides a grid format of normal precipitation. 2007-10-19 
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. 2007-10-18 
NOAA Weather Radio Podcasts The NWS is responsible for making its weather, water and climate information widely available to taxpayers using commonly accepted standards and technologies. Currently, the NWS provides only limited audio broadcasts of their NOAA Weather Radio All Hazards (NWR) via the Internet. The Voice Improvement Program (VIP) software on the NWR is able to convert the text transmitted to the Console Replacement System (CRS) into MPEG audio Layer-3 (MP3) files. Southern Region NWS offices are making these MP3 files available on the Internet as podcasts. Podcasting allows for publishing of audio programs to the internet and subsequent downloading of these programs to a personal computer or MP3 device. Users subscribe to the NWR podcast by using a freely available podcasting application that downloads the MP3 file automatically using an RSS (Really Simple Syndication) feed. Podcasting applications typically check for new content (new MP3 files) at user defined intervals. Once downloaded, the user can then listen to the podcast at his/her leisure (versus a radio broadcast of NWR). 2007-09-27 
Fire Weather Threat 4-Panel Graphic The Fire Weather Threat 4-Panel Graphic displays on the Internet several parameters that are critical for fire weather. In the upper left corner of the graphic is a ?Red Flag Risk Index? based on forecast minimum relative humidity (RH) and forecast maximum sustained wind. In the upper right hand corner is the Red Flag Risk Index for the current hour based on the GFE RH and wind observation database. In the lower left corner is the Haines Threat Index based on the forecast high level Haines Index and forecast minimum relative humidity. A second graphic is available based on the Forecast Haines Index and the current relative humidity from the GFE observation database. In the lower right hand panel three graphics reside. The probability of 25% or lower RH, 15% or lower RH, and the current observed RH. 2007-09-27 
National Air Quality forecast System (AQFS) Ozone (03) forecast A web-based presentation of gridded forecast O3 guidance originating from the Environmental Modeling Center (EMC) of the National Environmental Prediction (NCEP). The ozone data is displayed for a domain covering the northeast US for 1-hour and 8-hour averages. 2007-09-10 
Multimedia Weather Briefing The Multimedia Weather Briefing is an Internet-accessible multimedia file that provides information concerning hazardous weather events within the service area of a Southern Region office. The briefing provides a medium for supporting the planning activities of emergency response partners and customers by conveying (both aurally and visually, in non-technical terms) the forecaster's reasoning and confidence concerning upcoming hazardous weather events. 2007-08-27 
Gridded Weather Input for Fire Area Simulation Model (FARSITE) FARSITE is a deterministic model developed and used by land management agencies. FARSITE simulates the spatial and temporal spread and behavior of fires under conditions of heterogeneous terrain, fuels, and weather. Required FARSITE weather input consists of maximum and minimum relative humidity, maximum and minimum temperature, daily precipitation, wind speed and direction and cloud cover. FARSITE is an important tool that fire agencies use to help keep firefighters safe. Pursuant to the NWS mission of saving lives and property, NOAA/NWS forecasters have been manually supplying FARSITE weather input to fire managers for a number of years. 2007-07-20 
Day 4-8 Severe Weather Outlook Guidance The Day 4-8 Severe Weather Outlook product will consist of one graphic with an area (s) where severe weather is anticipated during the period. The severe weather threat areas will be depicted with a closed line and a label indicating the dates of the expected threat. A short 2-4 sentence paragraph will accompany the graphic to briefly describe the area depicted and occasionally describe the key reasons for the forecast. The forecast decision will be based on a variety of guidance information including the GFS, UKMET and ECMWF deterministic models, Medium Range (MREF) ensemble guidance and other statistical techniques. 2007-07-20 
WR Water Supply Page The WR Water Supply Page provides a single web page for displaying water supply forecasts from all WR RFCs. Forecasts are color coded according to percentage of normal runoff volume. More specific information for individual forecast points is available by drilling down to points. 2007-07-19 
California Fire Weather Web Page and Emergency Communications Center Dispatch Area (ECCDA) Forecast Summaries For the past several year, land management and fire suppression agencies serving California have expressed a need for more generalized fire weather forecasts suitable for agency radio broadcasts from Emergency Communication Center Dispatch Area (ECCDA) offices. These twice-daily fire agency radio broadcasts are critical to relaying life saving information to fire fighting crews in the field. The ECCDA Forecast Summary is a methodology developed to fulfill this need. 2007-07-19
