More Model Data
This site has excellent Global Forecast System (GFS) model imagery. Prior to the hardware failure they also had excellent GFDL and HWRF imagery. Check back on the site to see when it is upgraded. Other model data includes: North America Mesoscale Model (NAM) and NAM-HIRES, Global Ensemble Forecast System (GEFS), North American Ensemble Forecast System (NAEFS), Short Range Ensemble Forecast Model (SREF), Rapid Refresh Model (RAP), High Resolution Window (HRW) and Wave Watch III Model (WW3). Also includes Real-Time Mesoscale Analysis (RTMA), Upper Air Plots and Skew-T Plots.NCEP/EMC Cyclogenesis Tracking Page
This site displays models' projected path of low pressure areas all in one image. Once on the site, click the latest time in the left frame. From that you'll see a page full of different regions and models. If you are looking for a storm that doesn't happen to be near North America, such as in the Caribbean or across the Atlantic basin, scroll down the page and there is a table for the Atlantic basin. There are a variety of models to choose from, such as a multiple model, GFS, NCEP Ensemble, NAM, SREF Ensemble, UKMET (UK Meteorological), FNMOC (Fleet Numerical Meteorology and Oceanography Center) Ensemble, CMC (Canadian Meteorological Centre) and CMC Ensemble.The images show the path of a low with a line and also display the forecast pressure, which is quite helpful. You can view the text files if you cannot read the pressure on the images.Visit the Environmental Modeling Center at NCEP for more information and modeling. You can also visit the Climate Prediction Center (CPC) for other information on temperature and precipitation outlooks along with U.S. Drought Information. Two important areas of the CPC include the El Niño - Southern Oscillation (ENSO, also known as El Niño / La Niña - About on Wikipedia) and the Madden - Julian Oscillation (MJO - About on Wikipedia)
Scroll down in the right column of the page to "Model Data". You can select from a large variety of map types, select which model run you want to view (especially if the default run that loads is incomplete), which forecast hour you want to view (which also allows you to animate the entire run) and also select an opacity if you want to be able to view other features on the map. You can also zoom in and out and also pan the map. The WunderMap also has other model data available such as the ECMWF, NAM and Rapid Update Cycle (RUC) along with a massive amount of other weather features.
North American Region: Wind 850 and mslp or Geopotential 500 hPa and Temperature at 850 hPa
African Region (including eastern Atlantic): Wind 850 and mslp or Geopotential 500 hPa and Temperature at 850 hPa
You can learn more about the ECMWF Integrated Forecast System (IFS) here.
See the description under the GFS section for how to use the WunderMap interface.
The National Hurricane Center has now incorporated their NHC/TAFB Experimental Gridded Marine Forecasts into the proposed replacement of the National Weather Service Graphical Forecast Page. Select "Oceanic" as the geographic region and next to it select the forecast element you want to view. You can use the slider to view a different time period. You can learn more about how to use the interface here. You can view more information here on the NHC's site about the addition.
This site goes into more depth about the forecast track of lows. It shows you the line where the center is expected to travel along with some pressure and other data expected at the core. The phase diagrams are a very valuable resource to look at to learn more about the core of potential and current storms.
This site has great graphics that you can view, especially for the GFDL and HWRF. In addition to this part of the site and the cyclone phase diagrams, you can also visit some more experimental areas of the site.

This site is similar the FSU site. On this site the long range GFS is available.
The WunderMap contains excellent model imagery from the ECMWF and GFS that you can zoom in on and animate. (The HWRF is also available for active cyclones.) The WunderMap also has some of the most impressive weather overlays on the web in Google Maps. To access model imagery in the WunderMap scroll down in the right column of the page to "Model Data".
On the tropical weather page for the Atlantic you will also see additional model imagery (Click "Computer Models") for active storms with a great deal of other information on tropical cyclones. This part of the site also includes some of the SHIPS intensity model data on the model imagery.
This site tracks waves before and after they may or may not reach invest status. It also contains model data for the waves.Tropical Cyclone Guidance Project (TCGP) at National Center for Atmospheric Research (NCAR)
This site has select NHC model data plotted on images as well as model intensity data charted. It also has an archive of imagery, the latest SHIPS text output for a storm and links to other content. This site has the model system that the Colorado State model site had.e-WALL - The Electronic Map Wall at Pennsylvania State University (PSU)
Lots of models, including the GFS, UKMET, CMC and other data, including satellite imagery.
Click here for Tropical Atlantic e-WALL. (Notice in the left column the satellite views, including floaters.)
This folder contains a very detailed SHIPS output. The latest files, like the text model data folder, are at the bottom.
The compressed files in this folder contain the raw text data that Tropical Atlantic processes to present on our site. The easiest way to view this data is the processed output that we or another site generates.
