Horror Story Idea

So, it's brewing the same as big Hurr-y-cane Irma. A story that is.
A gang/couple decide they can use the biggest threat to the rich along the florida coast to snag some jewelry and high-end items as the storm hits. Then no one will be the wiser about any alarms. But they run into some thing...and they'll wish their fate lay in the hands of a storm instead of--what?
