A monster storm is barreling towards Jamaica … and dramatic video from a hurricane hunter shows the eye of Hurricane Melissa … and it looks like it’s going to be a big one.

Check out this clip from the inside of Melissa … meteorologist Jeremy DeHart shared it on social media today and he says it’s from a Teal 74 mission into the heart of the storm.

The video shows walls of clouds forming a cylinder as the plane flies through the eye … and DeHart says, “As clear of an eye as you will see in the Atlantic basin.”

Jamaica is bracing for impact — the storm is expected to hit Tuesday morning — and evacuations are underway.
