Probabilistic Tropical Cyclone Storm Surge and Tide Above Datum The Probabilistic Tropical Cyclone Storm Surge and Tide Above Datum consists of two suites of graphics. Probability of storm surge and tide above datum - series of graphics which show probabilities, in percent, of storm surge with tide exceeding 2 through 25 feet above North American Vertical Datum of 1988(NAVD88), at 1 foot intervals. Exceedance height of storm surge and tide above datum- series of graphics which show heights of storm surge with tide, in feet above NAVD88, which will be exceeded by a given percentage of storms. The suite of graphics range from 10 to 50 percent, at 10 percent intervals. John F. Kuhn 
Probabilistic Hurricane Inundation Surge Height The Probabilistic Tropical Cyclone Inundation Guidance products has been renamed the Probabilistic Hurricane Inundation Surge Height product. a.The Probabilistic Hurricane Inundation Surge Height (PHISH)guidance products consist of two suites of probabilities for the Gulf of Mexico and Atlantic coastal areas: 1) Probabilities, in percent, of inundation exceeding 0 through 20 feet above ground level, at 1 foot intervals (e.g., the probabilities in percent, of inundation exceeding 0 feet, 1 foot, 2 feet, .. 20 feet). 2) Probabilities of inundation heights (above ground level) being exceeded. The suite of products range from 10 to 50 percent, at 10 percent intervals. Each of the probabilities mentioned above will be provided out to 78 hours as a cumulative probability, defined as the overall probability the event will occur at each grid cell from the start of the run until some specified time (e.g. 0-6 hours, 0-12, 0-18, etc.)and as an incremental probability, defined as the probability the event will occur sometime during the specified forecast period (e.g. 0 - 6 hours, 6-12, 12-18, etc.) at each grid cell. The products are based upon an ensemble of Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model runs using the National Hurricane Center (NHC) official advisory and accounts for track, size, and intensity errors based on historical errors. Plans are underway for tide to be incorporated into the suite of products during the 2013 hurricane season. Long term plans are to incorporate waves and freshwater (i.e. precipitation runoff and river inflow). John F. Kuhn 
Changes to the Hurricane Local Statement Startinf 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. John F. Kuhn 
5-Day Graphical Tropical Weather Outlook The 2 day and 5 day Graphical Tropical Weather Outlooks have been combined into one product- graphical tropical weather outlook SEE catalog entry for the Graphical Tropical Weather Outlook. John F. Kuhn 
Tropical Cyclone Threat Grids in the NDFD The Tropical Cyclone (TC) Threat grids provide the worse-case plausible scenario or threat associated with the following hazards; wind, storm surge, flooding rain, and tornado. There are five levels to describe each TC Threat element; None, Low, Moderate, High, Extreme. The methodology for creating the grids takes in account the forecast magnitude and the associated forecast uncertainty for each of the hazards. The grids are produced only by coastal WFOs along the Atlantic and Gulf coasts as well as San Juan, PR whenever tropical cyclone watches and warnings are in effect for their area of responsibility John F. Kuhn 
Potential Storm Surge Flooding Map The Potential Storm Surge Flooding Map is a product that provides valuable information on potential storm surge flooding for areas along the U.S. Gulf and East Coast at risk from storm surge during a tropical cyclone event John F. Kuhn 
Storm Surge Watch Warning Graphic The storm surge watch/warning (SSWW) graphic highlights areas along the Gulf and Atlantic coasts that have a significant risk of life-threatening storm surge inundation from a tropical cyclone, subtropical cyclone, post-tropical cyclone,a potential tropical cyclone. he highlighted area designated the geographical areas at 2.5 km resolution under a gridded storm surge watch or warning.The graphic is intended to help users visualize areas most at risk from life-threatening surge, and serve as a call to action. All persons, regardless of whether or not they are in the highlighted areas shown by the graphic, should promptly follow evacuation orders and other instructions from local emergency management officials. John F. Kuhn 
GovDelivery Southeast River Forecast Center (SERFC) Subscription Service GovDelivery is a subscription service that serves as an efficient means of notifying partners of the issuance of critical SERFC products. GovDelivery specializes in the unique distribution of government information, and currently has contracts in place with many other state and federal agencies, including FEMA. John Feldt 
National Digital Forecast Database (NDFD) Convective Outlook Hazard Probability Elements As of April 30, 2009, the following Convective Outlook Hazard Probability elements prepared by the SPC are now available in the NDFD in operational status Categorical Convective Outlook for today (Day 1), tomorrow (Day 2), and the day following (Day 3) Probability of Tornadoes (Day 1) Probability of Hail (Day 1) Probability of Damaging Thunderstorm Winds (Day 1) Probability of Extreme Tornadoes (Day 1) Probability of Extreme Hail (Day 1) Probability of Extreme Thunderstorm Winds (Day 1) Total Probability of Severe Thunderstorms (Day 2 and Day 3) Total Probability of Extreme Severe Thunderstorms (Day 2 and Day 3)All of these elements are currently only available for the contiguous U.S. (CONUS) and the 16 pre-defined NDFD CONUS subsectors.The Convective Outlook Probabilities are issued for a convective day from 12 UTC to 12 UTC. Day 1 Outlooks are valid from 12 UTC on Day 1 (or, if issued after 12 UTC from the issuance time) to 12 UTC on Day 2. The Day 2 products are valid from 12 UTC on Day 2 to 12 UTC on Day 3. The Day 3 products are valid from 12 UTC on Day 3 to 12 UTC onDay 4.The Categorical Convective Outlook elements specify the perceived level of threat via the descriptive wording Slight, Moderate, and High Risk. However, these outlooks, do notdisplay the forecaster’s expectations of the individual severe weather hazards (large hail,damaging winds, and tornadoes)The individual probabilistic elements further express forecaster uncertainty of the individual severe weather hazards through the use of probabilities (i.e., percent likelihood of occurrence). In the Day 1 period, forecaster expectations of large hail, damaging winds, and tornadoes are explicitly conveyed in separate forecasts. By producing forecasts of each hazard individually, users who are sensitive to one particular threat (e.g., car dealers and large hail) can make more informed decisions. John Ferree 
National Digital Forecast Database (NDFD) Day 4 to 8 Convective Outlook Elements 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 and the National Centers for Environmental Prediction (NCEP). NCEP's Storm Prediction Center (SPC) operationally produces detailed outlooks and probability products for severe convective weather for Days 1, 2,and 3, and a more general Day 4 to 8 convective outlook (available as text and graphic products at http://www.spc.noaa.gov/products/exper/day4-8/). This element is a forecastfor organized severe thunderstorms over the contiguous United States. A severe weather area depicted in the day 4 to 8 period indicates a 30% or higher probability for severe thunderstorms within 25 miles of any point John Ferree 
Enhanced Product National Implementation of the use of 1 inch Diameter Hail Criteria The 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. John Ferree 
SPC Day 1-3 Categorical Convective Outlooks The Storm Prediction Center Day 1-3 Categorical Outlook include a defined areas of general non-severe thunderstorms, and 5 risk categories of severe convection (1 - Marginal, 2- Slight, 3-Enhanced, 4-Moderate, and 5-High). These outlooks previously included a defined area of general thunderstorms, and only three defined risk categories of severe convective weather (SLIGHT, MODERATE, and HIGH). The addition of “Marginal” and “Enhanced” categories will more closely compare to the SPC Day 1-3 Narrative and Probabilistic Convective Outlooks, and WFO products. John Ferree
