Great Lakes Ice OutlookIssued during winter. Provides guidance on expected ice growth and decay on the Great Lakes.
Gridded Day 2 and Day 3 Excessive Precipitation ForecastThe Gridded Day 2 and Day 3 Excessive Precipitation Forecasts are display the probability of precipitation amounts exceeding the flash flood guidance values issued by the River Forecast Centers at the time of product issuance. The product displays areas for the continental United States where the probability of precipitation amounts exceeding flash flood guidance is slight (defined as threat in the range 5 percent to less than 10 percent), moderate (defined as threat from 10 percent to less than 15 percent), and high (defined as threat 15 percent or greater). The River Forecast Centers do not currently issue flash flood guidance for days 2 and 3 so at this time the product will be based on the day 1 flash flood guidance.
Gridded Graphical Hazardous Weather OutlookThe Melbourne Weather Forecast Office (WFO) Gridded Graphical Hazardous Weather Outlook (gHWO) complements the text Hazardous Weather Outlook (HWO) by providing a graphical depiction of threat levels for the following hazards: lightning, tornado, wind, hail, (flash) flood, excessive heat, excessive cold, high wind, dense fog/smoke, fire weather, rip current, coastal flood, waterspout, marine wind/sea, and marine thunderstorm gust. The threat impacts are specific to the WFO county warning area (CWA) and marine area of responsibility (MAOR), and depict the geographical distribution and level of threat of each hazard.
Gridded Significant Wave Heights from the National CentersThe traditional format for the significant wave height products from the National Centers are graphical depictions of the observed and forecast wind-driven waves for the Atlantic and Pacific Oceans adjacent to the coasts of the Continental United States (US) and extending south over the Caribbean Sea and the west coast of Central America. These graphical products have been prepared for many years in the raster format by the Ocean Prediction Center (OPC) and the National Hurricane Center’s (NHC) Tropical Analysis and Forecast Branch (TAFB) and transmitted via radiofax and the internet. The production and dissemination of the traditional raster format for the graphical significant wave height products from the OPC and TAFB will continue. The gridded products are prepared for the initial wave heights and the 24 hour and 48 hour forecast wave heights in Gridded Binary (GRIB2) format. The gridded products are disseminated by the National Weather Service (NWS) Telecommunications Gateway to the Weather Forecast Offices (WFOs), National Centers, and other users. Users may also access these products via the internet at: ftp://ftp.mpc.ncep.noaa.gov/grids/operational/waves/atl ftp://ftp.mpc.ncep.noaa.gov/grids/operational/waves/pac
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.
Hawaiian One-Month and Three-Month Outlooks and Discussion.The Climate Prediction Center (CPC) issues a one-month and a series of thirteen three-month temperature and precipitation outlooks for selected cities in Hawaii and an accompanying prognostic discussion.
Hazard Grids in the National Digital Forecast DatabaseThe NWS provides access to operational and experimental gridded forecasts of weather elements (e.g., maximum temperature, sky cover)through the NDFD. The NDFD contains a seamless mosaic of digital forecasts from NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP). The hazard grids are prepared by all Weather Forecast Offices (WFO) and are available via the NDFD. Hazard grids are valid for more than two hours. The hazard grids depict all active long duration watch, warning and advisory hazards issued by NWS WFOs . The hazard grids include long duration coastal, marine, nonprecipitation, tropical and winter weather hazards. It also includes convective and some hydrological watches. It does not include the following short duration warnings: Tornado Warning, Severe Thunderstorm Warning, Extreme Wind Warning, Flash Flood Warning, and Special Marine Warning. It does not include the following Long Duration Watches and Warnings issued in RiverPro and WarnGen:Flood Watch for forecast points, Areal Flood Warnings and Flood Warnings for forecast points. In addition, it initially will not include Gale Warnings, Storm Warnings and Hurricane Force Wind Warnings issued in the Offshore and High Seas forecast by OPC and TAFB. The NDFD Hazard grid definition is defined as,a weather or hydrologic hazardous event issued for the protection of life and property and the enhancement of the national economy. The Hazards grid will be in experimental status in the NWS Alaska Region until further notice.
Helicopter Emergency Medical Services (HEMS) ToolThe Helicopter Emergency Medical Services (HEMS) Tool is an interactive online display that can overlay multiple fields of interest: ceiling, visibility, flight category, winds, relative humidity, temperature, icing, satellite, radar (base and composite reflectivity), G-AIRMETs, SIGMETs, METARs, TAFs, and PIREPs.All 3D data are interpolated to AGL altitudes and can be sliced horizontally on 1000 ft intervals up to 5000 ft. All data is time synchronized to go back up to 6 hours and forward up to 6 hours. The tool has high-resolution basemaps from ESRI, including colored relief, satellite and street views. Overlays include navigational aids, airports, and heliports for the entire United States. More detail is revealed as you zoom in and individual layers can be turned on or off independently. The HEMS Tool was specifically designed in response to a request by the Federal Aviation Administration to meet the needs of first responders who conduct short-distance, low-altitude flights.
High Seas ForecastDescribes potentially hazardous weather across large areas of the open ocean.
High Surf AdvisoryProvides notification of potentially life threatening surf conditions
HotSeat Warning SimulatorHotSeat is a web-based warning simulation tool. It uses archived WSR-88D data from actual events along with severe weather reports and damage survey photographs in a displaced real-time (DRT) mode to approximate the feel of issuing severe weather warnings in the National Weather Service. Upon completion of each event, the participant receives a score indicating his/her success in the simulation.
Hourly Multi-Sensor Precipitation Estimate Web-Based ServiceThe National Weather Service (NWS) collects rainfall data to support its forecast and warning operations. Individual River Forecast Centers (RFCs) and Weather Forecast Offices (WFOs) typically provide rainfall collectives in text and graphical formats for their areas of responsibility. This service provides unified hourly precipitation estimates for the Continental US and the Commonwealth of Puerto Rico on the Internet. The service includes graphics that display these precipitation data, as well as the ability to download the information in shapefile format for seven days post-event. This suite of graphics includes precipitation estimates for the last 1, 3, 6, 12, 24, 48, and 72 hourly accumulations, as well as "since 12z" accumulations. Hourly archives will be maintained.
Hours of Sunshine and Percent of Possible Sunshine ProductsThe Hours of Sunshine and Percent of Possible Sunshine Products will be graphical displays on the Internet of the number of hours of sunshine expected and the percent of total possible sunshine expected across the (PDT) County Warning Area (CWA). The products will be updated with each major Zone Forecast issuance. At 4 AM local Pacific Time, the forecasts will be for today and tomorrow. At 3 PM local Pacific Time, the forecasts will be for tomorrow and the day after tomorrow.
HPC 6hr Interval Quantitative Precip Forecast for days 4 and 5This Product provide QPF forecasts for days 4 and 5 in six hour increments. HPC forecasters prepare forecasts for 6hr periods out three days. In addition HPC forecasters prepare a 48hr forecast for days 4 and 5. Several RGCs have requested that HPC provide the day 4 and 5 forecasts in six hour increments rather than one 48 hr increment.This will augment the current 48 hr forecast prepared by HPC.
HPC Probabilistic Freezing Temperature ChartsThis product provides a probability that the temperature at a location will fall below 32 degrees Fahrenheit. This product is derived from the NDFD temperature grid data and the 2 meter temperature grid spread data from the GFS ensemble.
HPC Probabilistic Quantitative Precipitation ForecastsThis product provides a probabilistic forecast of rainfall over the continental U.S. in six hour increments.
HPC Probabilistic Winter Precipitation GuidanceThe Probabilistic Winter Precipitation Forecasts (PWPF) show the probability of various amounts of snow or freezing rain. They are based on the deterministic Hydrometeorological Prediction Center (HPC) Winter Weather Desk (WWD) accumulation forecasts, but are generated automatically using an ensemble of model forecasts along with the WWD forecasts
HPC Today's National Weather Chart in SpanishThis product is a Spanish language version of the HPC National Forecast Chart providing an overview of today’s national weather with an emphasis on hazardous and significant weather
Hurricane Local Watch/Warning ProductThe Hurricane Local Watch/Warning product is a segmented, automated product, with each segment being a discrete zone, containing tropical cyclone watches/warnings in effect, meteorological information, hazards (rain, storm surge, wind, tornadoes) and their potential impacts, and preparedness information at the Weather Forecast Office (WFO) level. The product is intended to be parsed by the weather enterprise. For 2015, the proposal is are for the Hurricane Local Watch/Warning Product to become the operational WFO flagship product for disseminating tropical cyclone watches/warnings for the Atlantic hurricane basin when a tropical cyclone affects land areas of their county warning area
Hurricane/Typhoon Local Statement (HLS)Starting with the 2015 hurricane season, Southern and Eastern Region WFOs having HLS responsibility will issue the HLS as a non-segmented product with no VTEC for land areas only. A new WFO product, “Hurricane Local Watch/Warning Product”, is now being used to issue tropical cyclone watches and warnings for land areas. The Marine Weather Warning (MWW) product is being used for tropical cyclone watches and warnings for marine zones in a WFOs county warning area. There will not be any change in the format to the HLS for Western and Pacific Region offices which issue the product for the 2015 Hurricane Season, except tropical cyclone watches/warnings for marine zones would be moved to the MWW. Plans for expanding the revamped HLS to Western and Pacific Region offices are being developed with implementation TBD.The HLS is an alphanumeric product alerting the public of present and anticipated local tropical cyclone affects. Coastal and selected inland Weather Forecast Offices issue HLSs when their County Warning Area and adjacent coastal waters is affected by a tropical cyclone watch/warning or evacuation orders.
Hydrologic Short-Term Meteorological Model-based Ensemble Forecasting System (MMEFS)The National Weather Service (NWS) Meteorological Model Ensemble River Forecasts web pages, graphics and text products are being produced by Eastern Region River Forecast Centers (RFCs) and the Southeast RFC to provide useful hydrologic information to users. The objective of this information is to provide short lead-time (<7 days) ensemble river forecasts using forcing fields provided by various meteorological ensemble systems.The purpose of the ensemble river forecasts is to provide users with a short-term (<7 days) situational awareness by providing the probabilistic exceedence information relative to NWS flood categories and providing the ensemble river forecasts that in turn show a range of outcomes. These web pages complement information contained in the current short-term deterministic hydrologic forecasts and internal NWS WFO-requested subjective contingency forecasts. This service will support the NOAA mission goals of serving society’s need for weather and water information and supporting the nation’s commerce, economy, and planning for the protection of life and property.
