Interesting note in the 5:00PM Discussion:

We would like to thank the crew of the latest Air Force Reserve
mission for their incredible service today. After beginning their
mission this morning before the center first moved onshore, the crew
went above and beyond, returning to Curacao to refuel, and then
heading back to Puerto Rico to catch Maria’s center when it first
moved back off the coast. The data collected by the crew was
incredibly important for us to analyze Maria’s intensity and
structure after moving across the island, and we are grateful for
their effort.
