| Tropical Cyclone Surface Wind Speed Probabilities - Graphical | The Tropical Cyclone Surface Wind Speed Probabilities product displays probabilities in percent of sustained wind speeds equal to or exceeding 34-, 50-, and 64-knot wind speed thresholds. These wind speed probabilities are based on the track, intensity, and wind structure uncertainties in the official forecasts from the National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center. | TCWindSpeedProbGraphical033006.pdf |
| Tropical Cyclone Surface Wind Speed Probabilities - Text | The Tropical Cyclone Surface Wind Speed Probabilities text product contains two parts. The first part, called Maximum Wind Speed (Intensity) Probability Table, provides over a five day period what the probabilities are for the maximum sustained (1-minute average) wind speed of a tropical cyclone for various intensity categories. A second part, called Wind Speed Probability Table for Specific Locations, provides probabilities, in percent, of sustained wind speeds equal to or exceeding 34-, 50-, and 64-knot wind speed thresholds. These wind speed probabilities are based on the track, intensity, and wind structure uncertainties during recent years in the official forecasts from the National Hurricane Center and the Central Pacific Hurricane Center and are computed for coastal and inland cities as well as offshore locations (e.g., buoys). | TCWindSpeedProbTextPDD2008.pdf |
| Tropical Cyclone Surface Wind Speed Probabilities in NDFD | The NWS provides access to operational and experimental gridded forecasts of weather elements (e.g., maximum temperature, sky cover) through the National Digital Forecast Database (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 Tropical Cyclone Surface Wind Speed Probabilities (TCSWSP) is an NCEP, event-driven product. The TCSWSP is an experimental product which will be made available via the NDFD. This product depicts probabilities, in percent, of sustained surface wind speeds. These probabilities are expressed for wind speed thresholds equal to or exceeding 34-, 50-, and 64-knots. These wind speed probabilities are based on the track, intensity, and wind structure (size in terms of radii) uncertainties in the official forecasts from the National Hurricane Center (NHC). The product will cover the continental U.S. and adjacent waters. | TCWindSpeedProbNDFD032007.pdf |
| Tropical Cyclone Track and Watch/Warning Graphic | The Tropical Cyclone Track and Watch/Warning graphic contains the storm's forecast track, a cone along the track based upon the average area of uncertainty for the position of the center, and coastal tropical storm and hurricane watches/warnings. The coastal watches and warnings display shows an approximate representation of coastal areas under a hurricane warning (red), hurricane watch (pink), tropical storm warning (blue) and tropical storm watch (yellow). The orange circle indicates the current position of the center of the tropical cyclone. The black line and dots show the NHC forecast track of the center at the times indicated. The NHC forecast tracks of the center can be in error, and the white areas indicate the increasing average area of uncertainty for the position of the center as a function of time. This product is also issued for subtropical storms.

| Tropical Cyclone Update (TCU) | The TCU is a brief alphanumeric text product which the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC) issue to inform customers of unexpected or sudden changes in a tropical cyclone or to post or cancel watches and warnings. NHC and CPHC issue TCUs on an event-driven basis in lieu of or preceding special advisories.
| TropicalCycloneUpdate.pdf |
| Tropical Cyclone Watch/Warning Product | The Tropical Cyclone Watch/Warning product (TCV) is based upon the Valid Time Event Code (VTEC). It summarizes all new, continued, and cancelled tropical cyclone watches and warnings issued by: the National Hurricane Center (NHC) for the U.S. Atlantic and Gulf coasts, Puerto Rico and U.S. Virgin Islands; and the Central Pacific Hurricane Center (CPHC) for the main islands of Hawaii. | TCVPDD2008-1.pdf |
| Tropical Cyclone Wind Field Graphic | This graphic illustrates the areas potentially being affected by tropical cyclone sustained winds of varying force. The graphic also shows an approximate representation of coastal areas under a hurricane warning, hurricane watch, tropical storm warning and tropical storm watch. The white dot indicates the current position of the center of the tropical cyclone, and the dashed black line shows the histosry of the center of the tropical cyclone. | tcwfg.pdf |
| Tropical Pacific Mean Sea-Surface Temperature (SST) Outlook | The Climate Prediction Center's climate outlook techniques rely significantly upon the slowly varying global SST field and do not have usable accuracy at long lead times. These SST outlooks make tangible the results of research activities by scientists. | SSTO.pdf |
| Tropical Streamline Surface Analysis | A graphic product issued from the WFO Honolulu, HI, that provides information on significant surface features over the Pacific Ocean Basin such as location of high and low pressure systems, areas of gale strength winds, and the Inter-tropical Convergence | TSSA.pdf |
| Tropical Surface Analysis | A graphic product issued from the Tropical Prediction Center and the WFO Honolulu, HI, that provides a depiction of significant surface features over the Tropical Atlantic and Pacific Ocean Basins. Features such as the location of high and low pressure s | TSA.pdf |
| Tropical Weather Discussion (TWD) | The TWD is an alphanumeric product providing information on current atmospheric conditions at the surface and aloft such as tropical cyclones, mesoscale and synoptic scale features, and areas of shallow and deep convection. This product is prepared over the tropical and subtropical Atlantic and Pacific ocean areas by the Tropical Prediction Center and the Honolulu Weather Forecast Office.

| Tropical Weather Outlook (TWO) | This PDD is updated for issuance of Special Tropical Weather Outlooks. There are no other changes to this product.
The TWO is a text product prepared by the National Hurricane Center and Central Pacific Hurricane Center for their respective areas of responsibility. It is a general assessment of activity in the tropics, pertaining to tropical cyclone formation by providing possible areas where tropical cyclones could development.

| Tropical Weather Summary (TWS) | PDD updated for the following: Effective with the 2009 season, the product changes from a narrative to a mainly tabular format.
The TWS is a monthly alphanumeric product issued by the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC) to summarize tropical cyclone activity for the previous month. NHC issues summaries for tropical cyclone activity over the Atlantic and eastern north Pacific (north of the equator and east of 140W longitude) basins. CPHC issues summaries for tropical cyclone activity over the central North Pacific (north of the equator between 140W and 180W longitude) basin. The centers issue new summaries the first day of each month from June through December. The last TWS of the tropical cyclone season (December issuance) covers activity for the entire season from June through the end of November. Effective with the 2009 season, the product changes from a narrative to a mainly tabular format. | TropicalWeatherSummary.pdf |
| Tucson, AZ WFO Precipitation Monitoring Page | The Tucson climate web page displays precipitation analyses for National Weather Service observation sites in southeast Arizona. This web page allows a person to select various methods for precipitation analysis with an emphasis on drought monitoring. Analyses can vary by length of time and geographic area of interest. Data is presented in a graphical form of time versus amount. | twcDM_pdd2.pdf |
| U. S. Drought Monitor | NOAA's Climate Prediction Center (CPC) and National Climatic Data Center (NCDC), the U.S. Department of Agriculture, and the National Drought Mitigation Center (NDMC) jointly issues this graphic summarizing the extent and intensity of drought conditions | USDM.pdf |
