Observation 6 - basically first pass through the eye. Probably encounter greater winds on later observations.

Maybe it could get < 910? It looks certainly feasible.

The winds have not dropped. That recon report came from the NW quadrant. The highest winds are typically found in the NE quadrant

Good job Cyclone. Where are you able to find the update on the vortex messages so quickly. The best I can do is the FTP on the NHC site, not as quick as yours.

Actually, one second doesn't technically count (one minute is the standard).

But, still, that first report is not the final determination.

There it comes more rapid than the NHC site.
