  In this paper we study the dynamics of the trapped region using a frame
independent semi-tetrad covariant formalism for general Locally Rotationally
Symmetric (LRS) class II spacetimes. We covariantly prove some important
geometrical results for the apparent horizon, and state the necessary and
sufficient conditions for a singularity to be locally naked. These conditions
bring out, for the first time in a quantitative and transparent manner, the
importance of the Weyl curvature in deforming and delaying the trapped region
during continual gravitational collapse, making the central singularity locally
visible.
