Sufficient conditions for a map having nonwandering critical points to be ${\mit\Omega} $-stable are introduced. It is not known if these conditions are necessary, but they are easily verified for all known examples of ${\mit\Omega} $-stable maps. Their necessity is shown in dimension two. Examples are given of Axiom~A maps that have no cycles but are not ${\mit\Omega} $-stable.
