Weatherlogics Surface Viewer

The surface maps are updated four times per hour at +10, +20, +30, and +40 minutes past the hour. Even though the map updates numerous times per hour, all observations are from the top of the hour. The map updates more than once because some observations from the top of the hour are slow to arrive and may not be available for the first update which occurs at +10 minutes. The update times are when updates are triggered in the server, so the new maps may not appear on this website until a few minutes later.
