Aviation Digital Data ServiceThe Aviation Digital Data Service (ADDS) makes available to the aviation community through the internet digital and graphical analyses, forecasts and observations of meteorological variables. Developed as the data distribution component of the Aviation Gridded Forecast System (AGFS), ADDS is a joint effort of NOAA Forecast Systems Laboratory (FSL), NCAR Research Applications Program (RAP), and the National Centers for Environmental Prediction (NCEP)Aviation Weather Center (AWC). ADDS makes access to National Weather Service aviation observations and forecasts easy by integrating this information in one location, and by providing visualization tools to assist the application of thisinformation for flight planning.
Aviation Digital Data Service Flight Path ToolThe FPT allows a user to view data along a specified route of flight. The user can view important weather information on a map. Points can be entered along a route, so that the data can be viewed in a vertical cross section. Weather information that can be displayed on the FPT horizontal and vertical cross section views includes, but is not limited to: Wind Temperature Relative humidity Icing potential Turbulence potential AIRMETs and SIGMETs PIREPs TAFs METARs
Aviation Tropical Cyclone Advisory (TCA)The TCA is an alphanumeric text product produced by hurricane forecasters consisting of information extracted from the official National Hurricane Center forecasts. The TCA is intended to provide short-term tropical cyclone forecast guidance for international aviation purposes.
Aviation Weather Center Impacts Terminal Aerodrome Forecast (TAF) BoardThe AWC Impacts TAF board is a time series display of weather conditions at select airports across the United States. Each box (hourly forecasts from TAF) is color-coded based on the level of the hazard. White represents no impact, yellow slight impact, orange medium impact, and red high impact. The letters in the box represent the cause of the hazard. They are as follows: -CIG – Ceiling (hundreds of feet, Above Ground Level [AGL]) -VIS – Visibility (statute miles) -WX – Weather (see legend) -WSpd – Wind speed (knots) -WGust – Wind gusts (knots)
Aviation Weather Warning (AWW)The AWW is a National Weather Service (NWS) operational warning for weather with the potential to impact ground operations at some airports. Specific warning criteria are decided by local airport management and the supporting Weather Forecast Office and
Aviation Winter Weather DashboardThe Aviation Winter Weather Dashboard depicts the potential winter weather impact to the Core 30 (minus Honolulu) airports. Updated four times per day, the web display shows the potential impact to each airport through a matrix of color coded boxes that depict nominal (green), slight (yellow), moderate (orange), and high (red) impact through eighty-seven forecast hours. The impact information is calculated using the Short-Range Ensemble Forecast (SREF) numerical weather prediction system
AWC PIREP Online Submission FormPilot Reports (PIREPs) are reports of meteorological phenomena encountered in flight. These reports assist other pilots, dispatchers, and flight planners with flight plan preparation, situational awareness, and operational decision making. The PIREPs are integrated into the NWS forecast production process to help improve the accuracy of the forecasts, which include human generated products such as AIRMETs and SIGMETs as well as automated products such as the Graphical Turbulence Guidance (GTG), the Current Icing Product (CIP) and the Forecast Icing Product (FIP). PIREPs are particularly valuable in areas where surface-based observations are unavailable. The Aviation Weather Center PIREP online submission form enables registered users to enter PIREPs electronically, which will be distributed and displayed graphically on the Aviation Weather Center’s website Users will be able to register at and submit their PIREPS at All users will be subject to validation on the basis of having (1) an active pilot’s license (2) a .gov or .mil email address or (3) a group ID number for airlines. All other account requests will be evaluated on a case by case basis.
Beach Hazards StatementThe Beach Hazards Statement (BHS) informs beachgoers and local authorities to a multitude of hazards including, but not limited to: rip currents (or other types of dangerous currents in the surf zone), unusually cold water temperatures, potential for lightning along the beach/shoreline, or unusual surf/wave conditions which do not meet advisory criteria. In coordination with other agencies (as needed), the product may also inform users of various types of environmental hazards (e.g. chemical spills, harmful algal blooms, high bacteria levels in the water, or potentially hazardous marine wildlife which may be impacting the area). The BHS is an Informational Statement which is used to describe hazards that do not meet Advisory, Watch, or Warning criteria, as well as hazards that do not have Advisory, Watch, or Warning criteria (e.g. rip currents, oil spills). The BHS provides additional, more targeted information to its customers and partners on hazards along beach/coastal areas and immediate adjacent waters in a single statement. All hazards will not necessarily apply to all NWS coastal offices, as each office has unique criteria for their area of responsibility.
Blowing Dust Potential ProductThe Blowing Dust Potential graphical forecasts are designed to provide customers enhanced information on the potential for blowing dust (low, moderate, high, very high) to reduce visibilities below 1 statute mile during the next two days for areas in the Pendleton County Warning Area (CWA) prone to blowing dust (primarily the Columbia Basin and Blue Mountain Foothills).
Bulleted Coastal/Lakeshore Hazard Message (CFW) and Marine Weather Message (MWW)This displays the CFW and MWW in a bullet style format
Bulleted Winter Storm (WSW),Non-Precipitation (NPW), and FireWeather(RFW) StatementsDuring long duration winter storm, non-precipitation and fire events affecting multiple forecast zones, WSW, NPW and RFW weather watch, warning, advisory products (WWA) can become very long and time consuming for forecasters to produce. The length of the product can make it difficult for users to quickly scan multiple forecast zones for vital storm information. Since 2009, starting with WFO Reno (which developed the software template) and expanding each year to over 100 WFOs in 2011, an experimental bulleted template for descriptive text in place of paragraphs has been used to produce long duration WSW, NPW and RFW WWA products within the AWIPS Graphical Hazards Generator (GHG) software. As of AWIPS Build 9.3 now being implemented in the field, GHG contains a baseline operational version of the software.
California Fire Weather Web Page and Emergency Communications Center Dispatch Area (ECCDA) Forecast SummariesFor 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.
CEILING HEIGHT AND SURFACE VISIBILITY INFORMATION ON THE MULTI-FORMAT FORECAST INFORMATION WEB PAGEAdvances in computer capabilities and web services technologies, as well as scientific advances in National Weather Service (NWS) software, have afforded an opportunity for the NWS to create ceiling height and surface visibility customer-based products and services. Information dissemination via the world wide web (www) allows customers to obtain higher resolution ceiling height and surface visibility information in a variety of formats on demand.
Center Weather Advisory (CWA)The National Weather Service's (NWS) Center Weather Advisory (CWA) is an aviation warning for conditions meeting or approaching national in-flight advisory criteria ( ie AIRMET, SIGMET, or SIGMET for convection) as described in NWSI 10-811.
Central Region Multimedia Weather BriefingThe Multimedia Weather Briefing (MWB) is an Internet-accessible multimedia file that provides information concerning hazardous weather events within the service area of a Central Region office. The MWB offers a combined visual/auditory platform for supporting the planning activities of emergency response partners and other key customers, as well as the general public by conveying forecaster reasoning and confidence concerning impending hazardous weather events, upcoming or current drought conditions, climate and hydrologic outlooks, etc. These briefings also serve as a means of communicating probabilities and other uncertainty information which can be used in risk reduction assessments which may impact preparations or actions made by our partners and customers
Changes to the Hurricane Local StatementStartinf 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.
Changes to the Tropical Cyclone Public Advisory for 2015The current NWS operational guidelines state that NHC and CPHC will issue public advisories (TCPs) at 2-hourly intervals whenever coastal tropical cyclone watches / warnings are in effect and coastal radars are able to provide reliable hourly center position estimates. When NHC and CPHC is issuing TCPs on 2-hourly cycles, hourly position estimates are issued (on the hour between TCP issuance) in the Tropical Cyclone Update (TCU; prior to 2013, the Tropical Cyclone Position Estimate was issued in these cases) to provide a continuous flow of information regarding the center location of a tropical cyclone when the center can be easily track with land-based radar. Although NHC typically mentions in the Tropical Cyclone Discussion and indicates in the TCP when 2- versus 3-hourly advisories will be issued, the less frequently used 2-hourly advisory cycle sometimes creates confusion among our core partners. This agenda item proposes that NHC and CPHC always remain on a 3-hourly TCP cycle whenever watches / warnings are in effect or a tropical cyclone is over land at tropical storm strength or greater. The elimination of the 2-hourly TCP cycle would preserve the issuance of public advisories at standard times during an event whenever watches or warnings are in effect. This change would also keep the issuance of public advisories out of the interval when NHC and CPHC forecasters are preparing the next forecast (e.g., the 9 a.m. intermediate advisory “B” must be prepared and sent while the 11 a.m. forecast is being developed). Maintaining public advisories on a 3-hour cycle will alleviate workflow issues while the new track and intensity forecast is being prepared and wind and surge watches / warnings are being collaborated.
CLIMAT Messages The program for the international exchange of monthly mean data is called the "CLIMAT" program. The World Data Center for Meteorology, operated by the National Climatic Data Center, collects CLIMAT messages for publication under WMO sponsorship.
Climate Diagnostics BulletinThe Climate Prediction Center (CPC) issues this monthly report on the status of the ocean-atmosphere climate system in the tropics and extratropics.
Coastal Waters Forecast ProductProvides marine weather information over the coastal waters - generally from the coastline out to between 20 and 60 miles from the coastline
Coastal/Lakeshore Flood Statement/Watch/WarningThe suite of products provides the public with statements, watches, and warnings of significant coastal/lakeshore flooding events.
Coded Marine ForecastProvides an abbreviated version of the Coastal Waters Forecast
Cold Advisory for Newborn Livestock (CANL) GraphicIn the winter of 2008-2009,NWS Glasgow ran this system. Due to significant livestock losses in other areas of the high plains during the winter of 2008-2009, additional NWS offices joined the experimental test period for the 2009-2010,2010-2011,and 2011-12 winter seasons including: WFO Aberdeen, SD WFO Billings, MT WFO Bismarck, ND WFO Glasgow, MT WFO Great Falls, MT WFO Pocatello, ID WFO Pendleton, OR Durint the 2011-2012 experimental test period, NWS surveyed other entities in the weather enterprise for their interest in providing this type of service to the livestock industry.
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.
