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. Carl Gorski 
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. Carl Gorski 
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. Carl Gorski 
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 Carl Gorski 
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. Carl Gorski 
GIS Compatible NDFD Data on the WFO Internet Page NOAAs National Weather Service (NWS) Weather Forecast Offices (WFOs) produce graphical forecasts for the National Digital Forecast Database (NDFD). The NDFD forecasts are available to the public in GRIB2 format, a World Meteorological Organization standard. Unfortunately, this format is not widely used outside of the meteorological community. In this project GRIB2 files from the MFR county warning and forecast area are converted to shapefile format and posted to the internet webpage. Carl Gorski 
Western Region Fire Weather/Marine Point Forecast Matrix (PFM) Land management agencies have expressed a need for easily accessible tabular forecast data that is tailored toward fire behavior applications. A fire weather version of the Point Forecast Matrix (PFM) table fits this need well because it allows agency specialists to quickly run simple fire behavior models for planning purposes. This is turn allows land management agencies to ensure the safety of fire crews as well as better plan prescribed burns and other projects in a cost and resource effective manner. Carl Gorski 
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). Carl Gorski 
Western Region Graphical Weather Story of the Day The Graphical “Weather Story of the Day” is a graphical representation (product) which depicts the most important weather feature in the forecast area of responsibility of individual NWS Weather Forecast Offices (WFO) in Western Region. The “Weather Story of the Day” is not time dependent. That is, the product depicts the most significant weather feature through the 7-day forecast period. A graphical user interface allows the forecaster to include a brief text, a few sentences in length, describing the “Weather Story of the Day” graphical product. If necessary the product may include a series of images to more clearly communicate complex weather situations. Carl Gorski 
WFO WRF_NMM The WRF NMM is run locally at the WFO. It generates hourly output data out to 48 hours. The high resolution model is used for operational forecasting and research. Model Output graphics, generated by GEMPAK software, are posted for 3 hourly forecast time steps to a local WFO web page. The fields include geopotential heights, vorticity, temperatures, dew point, relative humidity, wind, vertical velocity, freezing level, precipitation amount and type, seal level pressure, thickness, clouds, precipitable water, convective available potential energy (CAPE), and convective inhibition (CIN). The web page is a convenient way for the local customers to view the same meteorological forecast data as the local WFO forecaster. This model has been run operationally at WFO Sacramento since May 2009 and the PDD is being expanded to provide this capability to other WFOs in the WR. Carl Gorski 
Aviation Area Forecast (FA) Aviation Area Forecasts (FAs) describe in abbreviated language the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena below Flight Level (FL) 45,000 ft (450). The FA is a forecast of visual meteorological conditions(VMC), clouds, and general weather conditions over an area the size of several states. In Alaska, the FA also includes forecasts of Instrument Flight Rule (IFR) conditions as well as other AIRMET and SIGMET information on thunderstorms, wind, icing and turbulence. Over CONUS and Hawaii, the FA must be used in conjunction with the in-flight aviation weather advisories to understand the complete weather picture. Together, they are used to determine forecast en-route weather and to interpolate conditions at airports for which no Terminal Area Forecasts (TAFs) are issued. Carl Weiss 
Instant Messaging for NWS and Partners :NWSChat Instant Messaging (IM) is a real-time, Internet-based method of electronic communication between two or more parties. IM may also be referred to as "chat". Utilizing a software application known as a "chat client", multiple users can compose and send messages to each other in forums known as "chat rooms." In addition to manually composed mesages, chat sessions may contain various automated software-generated messages that convey information about disseminated National Weather Service (NWS) products. NWSChat is the name for the system providing IM capability to the NWS. NWSChat consists of hardware and software maintained by NWS and client software that can be accessed via a web browser or downloaded on the users computer. Carlos Diaz
