REMARKS:
Marcia underwent a period of very rapid intensification during Thursday. CIMSS
winds show approximately 15 knots of deep layer shear over the system.
The satellite signature improved markedly during the day with an eye becoming
visible from about 03Z, and it remains clear. Confidence of the LLCC position is
therefore high.
Using EIR from MTSAT DT 6.5 has been derived for the past 3 hours. CI raised to
6.5 due the consistency of those results over that time.
Recent movement has been to the south.
