| CEILING HEIGHT AND SURFACE VISIBILITY INFORMATION ON THE MULTI-FORMAT FORECAST INFORMATION WEB PAGE | Advances 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. | HourlyAvnMeteogramPDD.pdf |
| 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. | CWA.pdf |
| Central Region Multimedia Weather Briefing | The 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 | PDD_Official_MWB.pdf |
| 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. | pddclimat.pdf |
| Climate Diagnostics Bulletin | The Climate Prediction Center (CPC) issues this monthly report on the status of the ocean-atmosphere climate system in the tropics and extratropics. | CDB.pdf |
| Coastal Waters Forecast Product | Provides marine weather information over the coastal waters - generally from the coastline out to between 20 and 60 miles from the coastline | CoastalWatersForecast.pdf |
| Coastal/Lakeshore Flood Statement/Watch/Warning | The suite of products provides the public with statements, watches, and warnings of significant coastal/lakeshore flooding events.
| CoastalFloodW-W.pdf |
| Coded Marine Forecast | Provides an abbreviated version of the Coastal Waters Forecast | CodedMarineForecast.pdf |
| Collaborative Convective Forecast Product | The 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. | CCFP_PDD_Enhancement.pdf |
| Collaborative Surf Product | Surf 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. | PRH1.pdf |
| Convective SIGMET | Convective 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 | C-SIGMET.pdf |
| Cook Inlet Sea Ice Analysis | Aids ships navigating the ice-covered waters of Cook Inlet and into the Port of Anchorage | CISIA.pdf |
| 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. | CMI_v2.pdf |
| Crosswind Calculator Aid | The 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. | CrosswindProjectTJAUpdate.pdf |
| Current Icing Product (CIP) Severity | The 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.
