Hurricane Dorian is rapidly intensifying on Friday, as it is a category 4 hurricane with winds of 140 MPH, the NOAA Hurricane Hunters found during its flight through the storm.

During its flight through the core of Dorian, it found the pressure dropped from 970 MBs to 950 MBs during the evening. By 11 p.m., the pressure dropped even more to 948 MBs.

Hurricane warnings have been issued for the northern Bahamas, including Freeport and Nassau.

No watches have been issued for the U.S. yet, but hurricane watches are expected for the Florida coast Saturday.

The storm is still expected to maintain category 4 intensity through Tuesday. Forecast models still disagree on whether Dorian makes a direct landfall in Florida, or narrowly miss the state as it turns north.
