Collaborative Convective Forecast ProductThe Collaborative Convective Forecast Product (CCFP) is a graphical representation of expected convective occurrence at 2-, 4-, and 6-hours after issuance time. Convection is defined as a polygon of at least 3,000 square miles with coverage of at least 25% with echoes of at least 40 dbZ composite reflectivity and at least one echo top of 25,000 feet or greater. CCFP covers the contiguous 48 states and portions of Ontario and Quebec south of 48 degrees north latitude.
Collaborative Surf ProductSurf is the number one weather-related killer in Hawaii. More lives are lost to surf-related accidents every year in Hawaii than any other weather event. Between 1993 to 1997, 238 ocean drownings occurred and 473 people were hospitalized for ocean-related spine injuries, with 77 directly caused by breaking waves. This is a serious safety problem. The National Weather Service (NWS) Weather Forecast Office (WFO) in Honolulu wants to better serve the citizens of Hawaii and visitors to the islands who may not be familiar with ocean conditions. An evolving Collaborative Nearshore Swell and Wind Forecast for Oahu and improved web page will incorporate educational tools and forecast explanations for all levels of ocean-going customers. The collaborative nearshore swell and wind forecast will be disseminated to the public via the world wide web and other NWS dissemination methods, including the Family of Services and NOAA Weather Wire.
Convective SIGMETConvective Significant Meteorological Advisories (WST) is a text product describing the occurrence or expected occurrence of thunderstorms and related phenomena over the conterminous United States and adjacent coastal waters within 2 hours of issuance tim
Cook Inlet Sea Ice AnalysisAids ships navigating the ice-covered waters of Cook Inlet and into the Port of Anchorage
Crop Moisture Index.The Climate Prediction Center?s (CPC) and U.S. Department of Agriculture?s Joint Agricultural Weather Facility (JAWF) produces the Crop Moisture Index chart. The index indicates short term conditions.
Crosswind Calculator AidThe Crosswind Decision Aid is color-coded according to the degree of impact the wind will have on various runways green indicating little or no impact; yellow indicating marginal impact; and red indicating significant impact. Each color level is triggered based on a user-defined wind direction and wind speed threshold. The product also includes a Wet Runway/IFR factor that effectively lowers the crosswind speed thresholds.
Current Icing Product (CIP) SeverityThe Current Icing Product (CIP) is an automatically-generated index suitable for depicting areas of potentially hazardous airframe icing. This version of the CIP was updated in December 2006. The original CIP was implemented in 2002. The CIP algorithm is rooted in cloud physics principles that have been applied in the practical forecasting of icing probability and severity using research aircraft for nearly a decade. These principles and the resulting methods have also been applied to studies of icing incidents and accidents, as well as daily assessment of icing environments associated with icing pilot reports (PIREPs) over the United States and Canada at all times of the year.
D Region Absorption Prediction, Release 2The D-Region Absorption Prediction, Release 2 (D-RAP2) product provides a suite of graphic and text information about the global High Frequency (HF) radio propagation conditions related to the state of the ionosphere’s D-region. D-RAP2 will be web based ( and is an enhancement of the current D Region Absorption Prediction product ( D-RAP2 fills a void that exists in the current product by providing absorption information due to energetic proton precipitation at high latitudes. The web site provides: o A main page containing a global map of the highest HF frequencies affected by a 1dB attenuation, estimated recovery times, and links to subordinate pages. o Subordinate pages containing: north and south polar maps of the highest frequencies affected by a 10dB attenuation, and ASCII tabular values of total absorption at 10 MHz. o DRAP2 is updated every minute SWPC data and products are designed to provide accurate and real-time space weather information for the safety and benefit of our customers
Day 4-8 Severe Weather Outlook GuidanceThe 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.
Digital Wind and Wave Forecasts on Inland Lakes and ReservoirsWind and wave digital forecasts on inland lakes and reservoirs in text and graphical forecasts on the WFO web page. Wind and wave forecasts created within the GFE using the NOAA/GLERL wind/wave model.WInd wave forecasts for the lakes are produced using forecaster derived data.
Dry Lightning Potential IndexThe Dry Lightning Potential Index (DLPI) is a graphical product produced by forecasters at WFO Las Vegas (VEF) using GFE/IFPS. Ratings of Dry Lightning potential (numbered from 0 through 6) for the next three days (today, tomorrow and the next day) are calculated using forecasts of boundary layer relative humidity and static stability. The DLPI is intended to be used as general guidance, primarily for planning purposes. The DLPI is intended as a seasonal product, issued from June through October, when active wildfires are most likely to occur in our forecast area
Eastern Pacific Hurricane Season OutlookThe Climate Prediction Center (CPC) issues the Hurricane Outlook for the eastern Pacific east of 140? West. No outlook, however, can give certainty as to whether or not a particular locality will be impacted by a tropical storm or hurricane in any given year. CPC issues this outlook in cooperation with the Tropical Prediction Center and NOAA?s Hurricane Research Division.
Eastern Region National Digital Forecast Database (NDFD) Graphic Forecast DisplaysThe National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) National Digital Forecast Database (NDFD) Graphic Forecast Displays ( ccc is the WFO ID, are web-based presentations of digital forecast data originating from local Weather Forecast Office (WFO) digital databases. The data is displayed in a graphical form on a local scale.
El Nino/Southern Oscillation (ENSO) Diagnostic DiscussionThe Climate Prediction Center (CPC) issues this monthly bulletin to provide insight into climate outlooks by reviewing the potential effects of the ENSO.
Enhanced Product addition of Max Wind-Hail Size Coding Tag for Severe Thunderstorm Warnings and associated follow up staThe Central Region Severe Thunderstorm Warning (CR SVR) is an alphanumeric product providing short-fused warning in¬formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. Integrated Warning Team workshops, as well as several societal impacts groups, have indicated a desire by many emergency managers for a concise tag line on the end of the SVR product identifying maximum hail size and wind speeds expected for a given SVR warning. Local area sirens are typically alarmed for tornadoes only. Decoding this tag line will facilitate the capability for local area EMs to trigger sirens for particularly dangerous severe thunderstorm events when conditions exceed locally developed thresholds for thunderstorm induced wind and or hail size.
Enhanced Product Fire Weather Planning Forecast (FWF) Bullet Format A Fire Weather Forecast (FWF) that utilizes left-justified asterisks to begin each line of text. The asterisks help maintain proper word wrapping and indentations in the AWIPS text editor. This significantly reduces the amount of time needed to edit the product before dissemination.
Enhanced Product National Implementation of the use of 1 inch Diameter Hail CriteriaThe Severe Thunderstorm Warning (SVR) is an alphanumeric product providing short-fused warning in¬formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. In the Western Region (WR) and Central Region (CR) a Severe Thunderstorm Warning is currently being issued experimentally based on expectation of winds gusting to 58 mph or greater and/or hail of one (1) inch diameter or greater. Pending successful completion of this experiment, all NWS sites will issue Severe Thunderstorm Warnings based on these criteria.
Enhanced Winter Weather Guidance Product SuiteThe Hydrometeorological Prediction Center (HPC) proposes to produce probability guidance for three specific snow/sleet accumulation thresholds per forecast day out to Day 3. HPC will also generate separate probability graphics for the exceedance of freezing rain. In addition a single graphic will depict both HPC forecast position of significant surface low pressure centers over the contiguous U.S. and conveyance of uncertainty of the forecast position. This will be depicted in 12 hour increments out to Day 3.
Enhancement to National Spot Webpage: HYSPLIT Trajectories Request Function The Weather Forecast Office (WFO) NWS Spot webpages provide a nationally uniform portal for NWS customers to request, receive, and leave feedback for site specific spot forecasts. As of September 19, 2011, all WFO NWS Spot webpage hosted a new functionality for requesting HYSPLIT (Hybrid Single Particle Lagrangian Integrated rajectorymodel) trajectory runs from NOAA’s Air Resources Laboratory (ARL) on an experimental basis. On October 20, 2013 this functionality became operational. Trajectory elements will be available based on the North American Mesoscale Model (NAM) for the CONUS and on the Global Forecast System (GFS) for Alaska and Hawaii. The HYSPLIT trajectories Request Function will allow users to request HYSPLIT trajectory runs at 500, 1500, and 3000 meters for the latitude/longitude of the spot request. The trajectory runs will begin at the specified ignition time on the spot request. To request HYSPLIT trajectories with a spot request, the user must enter the phrase ..."hysplit to requester email address" in the remarks section of the spot request form. The HYSPLIT trajectory raw data, as well as gif and kml files, will be sent to the specified email address.
Enhancement to the National Snow Analysis: NOHRC Snow Model and Forecast Products ExpansionThe NOHRSC is expanding the spatial domain of its gridded snow model into Canada to include the Great Lakes drainage area. Additionally, the NOHRSC is executing the model in a 72-hour forecast mode. The Rapid Refresh (RR) model forces the first 18 forecast hours and the North American Mesoscale (NAM) model forces the remaining 54 forecast hours.
Ensemble Trace plotCurrently the National Weather Service (NWS) River Forecast Centers (RFCs) and Weather Field Offices (WFOs) produce a wide variety of river forecasts, which indicate current and future river conditions. The Ensemble Trace Plot prepared by the North Central River Forecast center (NCRFC) will be issued as a Web page graphic. The graphic will be for the NCRFC?s area of responsibility. It will be issued once a month (after the Climate Prediction center (CPC) outlooks are released at mid-month). It will cover the three month period after the issuance (for example, graphic released around May 26 will cover June-August period).
Expected Value plotDescription: Currently the National Weather Service River Forecast Centers and Weather Forecast Offices produce a wide variety of river forecasts to indicate current and future river conditions. The Expected Value graphic indicates timing and confidence levels for forecast stages for a selected time-frame, generally 90 days. This would provide an overall range of expected hydrologic conditions based on computed probabilities. The Expected Value Graphic will be issued as a web-based graphic for NCRFC?s area of responsibility. It will be issued once a month after the Climate Prediction Center outlooks are released at mid-month to cover the ensuing three month period (i.e. graphic issued around May 26 will cover the period from June-August).
Experimental Graphical Forecasts for AviationIn May 2015 the National Weather Service received a formal request from the Federal Aviation Administration (FAA) for the NWS to cease production of textual Area Forecasts (FAs), contingent upon the provision of equivalent meteorological information in support of aviation.The Graphical Forecasts for Aviation include observations and forecasts valid for the continental United States. Observational data and warnings are time synchronized and available by the hour for the current time and the prior six hours. Hourly model data and forecasts, including National Digital Forecast Data (NDFD), are available to 15 hours in the future. Wind, icing and turbulence forecasts are available in 3000 ft. increments from the surface up to 18000 ft. MSL, and in 6000 ft. increments from 18,000 MSL to FL420 (42,000 ft. MSL). Turbulence forecasts are also broken into LO (below 18,000 MSL) and HI (at or above 18,000 MSL) graphics. A maximum icing graphic and maximum wind velocity graphic (regardless of altitude) are also available.Multiple fields of interest are combined in categories that the user is able to select from the top level Weather menu. The data for each category is determined by the time period, observations (current time and the prior six hours) and forecasts (valid up to 15 hours in the future). Additional information is available in text format when mouse-clicking on the map or using the hover function. The “Configure” menu enables the user to customize the satellite and radar displays in addition to choosing parameters for the observations and aviation advisories displayed. Imagery, observations, and forecast graphics are overlaid on 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.
Experimental Impact Based WarningsThis is an expansion of the NWS Experimental Central Region Impact Based Warning demonstration in 2012 and 2013.Severe Thunderstorm Warning (SVR), Tornado Warning (TOR) and Severe Weather Statement (SVS) products will be stratified into categories distinguishing extreme cases from base convective warnings. Additional enhanced wording will be included to convey information about associated impacts, specific hazards expected, and recommended actions, both within the bullet statements and as part of the tag line codes.Based on feedback from the Central Region 2013 Experimental Impact Based Warnings, the 2014 demonstration will include some changes. The most significant change for the 2014 national experiment is that the impact statements for “CONSIDERABLE” and “CATASTROPHIC” serve as markers of confidence of tornado occurrence, with both reflecting an “elevated tier” of tornado damage and risk. The term CATASTROPHIC will only be used when a tornado is striking an actual community. Issuing enhanced convective warnings in 2014 will be the 38 Central Region Weather Forecast Offices (WFOs), 5 WFOs within NWS Southern Region (Norman, OK; Tulsa, OK; Jackson, MS; Lubbock, TX and San Angelo, TX); 1 WFO within NWS Eastern Region (Blacksburg, VA); and 2 WFOs within NWS Western Region (Great Falls, MT and Glasgow, MT).
Extended Convective Forecast Product (ECFP)Automated probabilistic 24 hour thunderstorm outlook based on SREF Calibrated thunder guidance. This automated graphical forecast is created from the Short Range Ensemble Forecast (SREF) Calibrated Thunderstorm output. Contours are drawn at 40, 60, and 80% probability of “thunderstorm” (not convection) using CCFP-like shading. Hashed areas represent 40-59% probability, solid lined areas represent 60-79% probability, and solid blue filled areas represent greater than 80% probability. The automated graphic uses the 09Z initialization of the SREF valid for 18Z-00Z the next day
