What would the higest pressure be for a hurricane

Some hurricanes have had pressures that never went below 1000mb. However, it's very rare.

Examples:
Hurricane Bob 1985
Hurricane Frances 1986
Hurricane Danny 2003

Under normal circumstances, a small 65 kt hurricane in the deep tropics would have a pressure around 995mb. That drops as it grows and latitude increases. In the most extreme cases, tropical storms have had really low pressures - the lowest I remember ever seeing in an advisory is 958mb.

I cant seem to find the Floater on Debby. Does anyone have a link to that? Thanks.

[Texashawk]

So, if Debby sits too long and gets strong enough, would it be more influenced by the ridge of high pressure, pushing it more west, or does it not matter at this point and she's going NE no matter what?

[Lorenzo]

What is the blob off the yuctan could it develop and head to sw Florida .And is there anything else we have to watch?

[Peach]

General question from someone who is only an avid weather watcher: Is Debbie an 'average' size tropical storm? The NHC listed size, and the book info I have from books indicates she is not large. Is the fact she is in the gulf what makes her seem large to me?

The overall circulation is not a tight one as normally occurs in most of Tropical Cyclones so on that regard, is not small.

Thank you, rain has died down some in NE Fla., but I keep reading and hearing 5-10 unches. The St. Mary's river, which is/was still low, even after Beryl, is rising. Some living near the river are leaving.

It's hard to get a hurricane without a central core or any deep convection over water. It's struggling right now in a harsh environment.

I agree. Amazing that the pressure dropped to 990 mb though.
