I think they will on the 2pm advisory or a special advisory. I'd estimate it at 75kt.

Why 75kt? Wait for more recon data, may be 65kt at this time.

Finally she is strengthening. I say Flo can hit 960's tomorrow or lower.

981 + satellite estimates. That is my personal estimate.

But since there is recon, satellite estimates won't be used.

Finally some strengthening... The outflow (particularly in the western semicircle) has looked very good today. I've come to associate the "scalloped" appearance characterizing the outflow in the western half of Florence to moderate to strong intensification. The very large size of the wind field is likely keeping the winds a tad lower than would be expected for a ~980mb storm. Fortunately for Bermuda, Florence's resistance to strengthening up to now has likely spared the island from being battered by a major hurricane. The window is pretty small now for further intensification. That said, it may pick up some intensity solely from an increase in forward speed as the upper-level trough to its northwest picks it up and zooms it north-northeastward. Of course, this would be a highly asymmetric response, with stronger winds to the right of the path and weaker to the left (which is good for portions of the Canadian coast which may otherwise have felt Florence more strongly).

Where is the data that supports the upgrade? Frances had lower millibars in was a tropical storm. Heck last few years I'v seen storms supportive of cat3 pressures not even tropical storms.

I haven't seen any minobs since 524z. That's just as they were passing through the center.

Until the report of 84kts at flight-level just received, which validates the Cat 1 intensity.

That's because it's on tape. Just before 2pm they had announced it was upgraded. They are no longer live.

I've noticed that TWC occassionally goes into a "loop" mode during the overnight hours (particularly when no significant weather is affecting the US; well, when no significant weather is affecting the population centers in the eastern US). If you notice the times when voices crack, etc, you'll see that the sometimes aire the 1100pm-1200am hour for the next several hours (until the early morning crew starts live at like 5am). I've noticed this before, and I assume that's what's going on now.
