Map Information

This nowCOAST™ geolinks map service provides maps depicting the locations where NOAA point forecast guidance or predictions are available along with URLs to NWS or NOS web pages displaying the latest forecast/predictions. Specifically, the map service provides links to point guidance for the following products: 1) Model Forecast Point Guidance from NWS and NOS forecast modeling systems and 2) NOS Astronomical Tide Predictions.

The hyperlinks to the point forecast guidance can be accessed by performing an identify or query operation on the desired map layer, which will return the attributes of any matching feature(s). The hyperlink is stored in the "URL" attribute field.

Model Forecast Point Guidance

This map layer procides geo-referenced hyperlinks to the latest NWS meteorological model forecast guidance and NOS and NWS oceanographic forecast guidance at specific geographic locations (i.e. forecast points). The different types of forecast guidance are described below.

Weather Model Output Statistics (MOS) Forecast Guidance

This layer provides hyperlinks to NWS computer-based weather point forecast guidance called Model Output Statistics (MOS). MOS is a numerical-statistical weather forecast technique and typically provides objective forecasts of sensible surface weather elements including: daily maximum and minimum temperatures; 2m air temperature and dew point temperature; wind speed and direction; categorical cloud, precipitation, and snowfall amounts; categorical precipitation type, ceiling height, visibility, and obstruction to vision; and the probability of precipitation, thunderstorms, severe weather, freezing precipitation, and snow. MOS guidance is generated four times per day using inputs from different NWS/NCEP numerical weather prediction forecast modeling systems. The technique uses predictions from the latest forecast cycles of the NWS/NCEP Global Forecast System (GFS), NWS/NCEP North American Mesoscale (NAM) numerical weather prediction model, and GFS Extension. The text bulletins containing MOS guidance from these three runs are identified with the notation MAV, MET, and GFSX, respectively. In addition, MOS forecast guidance is also generated four times per day for 121 marine sites (e.g. fixed buoys, C-MAN stations) located in and around the continental United States, Alaska, and Hawaii. The marine guidance includes forecasts of wind direction (WD) and wind speed (WS) at the observing height, and for wind speed adjusted to be consistent with a measurement height of 10 m above ground or water surface (WS10). The wind direction forecasts are rounded to the nearest degree and wind speed forecasts to the nearest knot, air temperature (TMP) and dew point temperature (DPT) rounded to the nearest degree Fahrenheit. The marine guidance is available forecast projections 6 through 78 hours in advance at 3-hr increments, from the initial model times of 0000, 0600, 1200, and 1800 UTC. The guidance is presented in table format. More information on NWS MOS predictions and how to read the MOS output tables can be found at http://www.nws.noaa.gov/mdl/synop/products.php.

Water Level Model Forecast Guidance

This layer provides hyperlinks to the latest water level forecast point guidance from NOS and NWS numerical oceanographic forecast model forecast modeling systems. Specifically, the layer contains links to time-series plots displaying guidance from 1) NOS coastal, estuarine, and Great Lakes numerical ocean circulation forecast modeling systems and 2) NWS Extratropical Storm Surge (ETSS) Model. The links are to NOS/CO-OPS or NWS/MDL web pages displaying time series plots of guidance for the next few days from NOS forecast systems and NWS ETSS Model, respectively. In some locations, water level forecast guidance is available from BOTH the ETSS model and a NOS forecast model (Links to point forecast guidance from NOS Extratropical Tide and Surge Operational Forecast System (ESTOFS) are not presently available on nowCOAST™).

Water Currents Model Forecast Guidance

This layer provides hyperlinks to the latest point forecast guidance of water currents from NOS numerical oceanographic forecast model forecast modeling systems. These include forecast systems for coastal waters, estuaries, and the Great Lakes. The links are to NOS/CO-OPS web pages displaying time-series plots of guidance for the next 48 to 60 hours.

Sea Surface Temperature Model Forecast Guidance

This layer provides hyperlinks to the latest point forecast guidance of water currents from NOS numerical oceanographic forecast model forecast modeling systems. These includes forecast systems for coastal waters, estuaries, and the Great Lakes. The links are to NOS/CO-OPS web pages displaying time-series plots of guidance for the 48 to 60 hours.

Salinity Model Forecast Guidance

This layer provides hyperlinks to the latest point forecast guidance of salinity from NOS numerical oceanographic forecast model forecast modeling systems. These include forecast systems for coastal waters, estuaries, and the Great Lakes. The links are to NOS/CO-OPS web pages displaying time-series plots of guidance for the next 48 to 60 hours.

Astronomical Tide Predictions

This layer includes links to to NOS' official astronomical tidal predictions for primary and secondary water level stations. The tidal predictions were generated using harmonic prediction, a method of predicting tides by combining harmonic constituents into a single tidal curve. The predictions are made at stations which have officially accepted harmonic constituents and accepted datums. These reference stations include both presently operating and historical NOS water level observing (i.e. tide) stations. The links are to NOS/CO-OPS web pages displaying time-series plots of tidal predictions for the next few days.

Background Information

The maps of the NWS and NOS point forecast locations are obtained directly from harvesting NWS/MDL and NOS/CO-OPS inventories of forecast point locations and NOS/CO-OPS tide prediction locations.

Time Information

This nowCOAST™ map service is not time-enabled.
