The maximum wind in the delta on Tuesday via the western Caribbean was 145 miles (Type 4).

The rapid intensification of the delta was due to an environment High sea heat content Nowhere in the tropical Atlantic bed, low air cut and sufficiently humid air, a The infamous area for rapid intensification in October, According to Sam Lillow, a NOAA scientist based in Boulder, Colorado.

The small size of the delta also helped to intensify very quickly.
