Observations of the Sgr A complex with the VLA reveal that the diffuse structure surrounding Sgr A East and West consists of two extended components. One is a 20-pc-diameter halo which appears to be associated with the nonthermal Sgr A-E shell source, and which is elongated along the galactic plane. The second component is a set of narrow radio protrusions from the Sgr A-W complex which run perpendicular to the galactic plane. A few of these protrusions appear to merge smoothly with the arms of the inner ''3-armed spiral'' structure of Sgr A-W. These protrusions are discussed in the context of a model of a directed wind; magnetic fields may play some role in directing and collimating them.
