From the TROPICAL STORM FRANKLIN DISCUSSION NUMBER 9 (NHC) at 11am
Quote:
EVEN THOUGH THE CENTRAL PRESSURE IS STILL ABOVE 1000 MB. THE INITIAL INTENSITY IS BEING INCREASED TO 60 KT FOR THIS ADVISORY...BUT THE INTENSITY COULD BE HIGHER SINCE FRANKLIN IS EMBEDDED IN A REGION OF MUCH HIGHER THAN AVERAGE SURFACE PRESSURES.
From what I understand, the important thing to know is the surrounding pressure - it's the pressure *difference* that is one indicator of intensity.,,,
