Rapid deepening is a condition that happens when the minimum sea-level atmospheric pressure of a tropical cyclone goes down at lot very quickly. The National Weather Service describes rapid deepening as a decrease of 42 millibars in less than 24 hours.[1] However, this phrase is usually applied to most storms that are quickly becoming stronger.
