It’s a unit of atmospheric pressure. Hurricanes happen when a low-pressure system in the tropics builds up and starts to spin and gets fueled by warm air/water coming in. Lower pressures draw in more air/water and correlate to larger storms.

So when the pressure in the eye drops significantly, the storm is going to intensify soon after.
