Michael:  And one more - contourf will die if you there are no contours 
at the requested levels.  The error message looks like this:

Traceback (most recent call last):
  File "plotprecip.py", line 52, in <module>
    cs = m.contourf(x,y,data,clevs,cmap=cm.s3pcpn)
  File "/Users/jsw/lib/python/matplotlib/toolkits/basemap/basemap.py", 
line 2425, in contourf
    CS = ax.contourf(x,y,data,*args,**kwargs)
  File "/Users/jsw/lib/python/matplotlib/axes.py", line 5017, in contourf
    return mcontour.ContourSet(self, *args, **kwargs)
  File "/Users/jsw/lib/python/matplotlib/contour.py", line 460, in __init__
    self.ax.add_collection(col)
  File "/Users/jsw/lib/python/matplotlib/axes.py", line 1140, in 
add_collection
    self.update_datalim(collection.get_datalim(self.transData))
  File "/Users/jsw/lib/python/matplotlib/collections.py", line 142, in 
get_datalim
    offsets, transOffset.frozen())
  File "/Users/jsw/lib/python/matplotlib/path.py", line 481, in 
get_path_collection_extents
    raise ValueError("No paths provided")

To trigger this, try running the plotprecip.py basemap example.
