Delta was first born as Tropical Depression Twenty-Six late Sunday night while it was only 75 miles south of Kingston, Jamaica.
By Monday morning, it was already Tropical Storm Delta, the 25th named storm of the 2020 Atlantic hurricane season.

That's the fastest tropical-depression-to-Category-4 intensification rate on record in the Atlantic Basin, according to Sam Lillo, a NOAA scientist based in Boulder, Colorado, and Tomer Burg, a PhD candidate at the University of Oklahoma.
Lillo and Burg found Hurricane Keith was the previous such record-holder, doing so in 42 hours also in the western Caribbean Sea east of Belize in late September and early October 2000.

These rapidly intensifying tropical cyclones could become more common in a warming world, according to a recent study by Kerry Emanuel, an MIT scientist.
By 2100, the chance of a hurricane's winds increasing by 70 mph or greater in 24 hours right before landfall is expected to be once every 5 to 10 years, according to Emanuel. That's an increase from a rate of once every 100 years in the late-20th-century climate.

Hurricane Delta is likely to be the 10th named storm to landfall in the mainland United States during the 2020 Atlantic hurricane season, breaking a record that has stood for more than a century.
Delta is expected to hit the northern Gulf Coast Friday into early Saturday. When it does, the mainland U.S. will have seen 10 landfalls from tropical storms and hurricanes this year since the barrage began in late May.
That would break the 1916 record of nine mainland U.S. landfalls in a season, according to Phil Klotzbach, a tropical scientist at Colorado State University.
Four of the landfalls so far in 2020 have been from hurricanes, including Hanna, Isaias, Laura and Sally. Delta is currently forecast to be the fifth hurricane landfall of this year.
Five U.S. hurricane landfalls would be more than double the average of one to two hurricane landfalls per year, according to NOAA's Hurricane Research Division.

After Oct. 4, an average hurricane season delivers another two named storms. So it's possible we're not done after Delta, as far as U.S. impact is concerned.
