With respect to TC Winston, the Nadi RSMC has now completed their reanalysis of the intensity of TC Winston. They have now found a peak intensity wind of 150 knots with peak minimum central pressures in the 884-886 hPa range (Nadi adjusted its TC module to come up with the revised minimum central pressure data). When performing Dvorak Analysis, the following were arrived at:
At 20/02:0000UTC - Analysis based on Warm Medium Grey (WMG) Eye in Cold Medium Grey (CMG) Surr with banding yields a Current Intensity(CI) value of 8.0. A CI value of 8.0 yields 10-minute mean wind intensity of 150 knots (as opposed to the original value of 160 knots) A CI value of 8.0 was analyzed from 20/02:0000UTC till 20/02: 0600UTC.
Nadi recognized that their original pressure values needed to be revisited, and so they readjusted their TC Module columns/figures inputs in order correct the pressures.
As such, the revised version of SPEArTC reflects updated wind and pressure data for TC Winston from 18UTC on 02-19-2016 through 06UTC on 02-21-2016 in the revised dataset. The determination of these values is purely under the purview of RSMC Nadi and their internal procedures; SPEArTC merely reflects the data provided; so if anyone has any disagreements with the data for TC Winston, you will have to take that up with RSMC Nadi; I have no control over that other than to have pointed out to them that their previous values were in world record territory; and so, the values are now still rather intense, but no longer in world record territory.
