Narrative:
VOR runway 13L approach to jfk. First officer started down from MDA (800 MSL). We received a low altitude alert from tower. We appeared to be high on the VASI. Altimeters were set correctly. First officer leveled off momentarily, and then resumed descent. Moderate rain may have partially obscured VASI, which showed high at time of descent.
