Notes:

• Online data here go back 36 hours. However, you can go back much further (years) in time at our archived data site.
• The station plot legend is shown here.
• Use highest density setting for most regions outside of North America.
• Station idenitiers (for centerring the map) can be specified as ICAO identifiers (e.g. KALB) or WMO number (e.g. 72518) or latitude,longitude pairs (e.g. 42.75,-73.80). This feature will center the map at that location and will enable the user to zoom in or out by setting the zoom factor. The zoom factor does not work for a standard pre-defined region.
• The 912x650 size works best for full page 8.5"x11.5" printing, if you select the landscape orientation using the "Properties" or "Preferences" option of the print window.
• NCEP frontal position data are updated every 3 hours and are valid for 00Z,03Z,06Z,09Z,12Z,15Z,18Z, and 21Z and usually become available anywhere from 1h+30m to 1h+50m after the valid times. Choosing an intermediate valid time will generate a map for the previous valid time. A blank map will be generated if the latest data are reqested for the most recent valid time and data have not yet been received.
