[gradsusr] Hurricane Track Map oddities

With each iteration of calls to aminlocx() and aminlocy() as you loop over time steps, try recentering the domain on the previous SLP minimum and restricting the size of the radius — i.e. how far away from the current minimum you want to look for the next minimum. You could also do a check of each new position to make sure it is reasonably close to the previous position and if not to print out an error message. If the hurricane is moving very fast, or there are other systems nearby, you can get spurious results from the SLP minima calculations.

I’ve tried using the cone.gs script to plot the uncertainty track and also the ensemble track map however both appear to be getting confused by a secondary low forming which throws off the tracks? I was wondering if anyone has had this issue when dealing with ensemble tracks before.
