1.5 megaton ground-burst at MacDill AFB, Tampa, FL USA:

Tampa Bay has an average depth of approximately 3m (12ft); it isn't mentioned but given the overpressure from the explosion it is likely a great portion of the bay would, for a few moments, cease to exist. Much of it would be flash-vaporized and fall on the rest of Hillsborough County and points west and northwest as heavy water rain fallout. Seawater rushing back in after the initial detonation would hit the sun-hot surface of the tarmac and flash into even more radioactive steam.
The comment in...I want to say it's Howling Wilderness? Or may be another module...about exotic wild animals that had "escaped from a theme park"? Yeah, Busch Gardens, Tampa is about 5 miles from the outer edge of the blast. Those animals would be dead within a day from the 3rd degree burns they'd suffered. If not, then from fallout, and failing that from starvation if they were locked in enclosures.
