  We examine the growth of the Weyl curvature in two examples of naked
singularity formation in spherical gravitational collapse - dust and the Vaidya
spacetime. We find that the Weyl scalar diverges along outgoing radial null
geodesics as they meet the naked singularity in the past. The implications of
this result for the Weyl curvature hypothesis are discussed. We mention the
possibility that although classical general relativity admits naked singularity
solutions arising from gravitational collapse, the second law of thermodynamics
could forbid their occurrence in nature. The method can also be used to compare
the relative importance of initial data and that of the energy-momentum tensor
in deciding the metric solution in any general case.
