Jeanne Strengthening Now a Category 3 Hurricane

10:45AM
Hurricane Jeanne is now category 3 with 115MPH winds pressure down to 955 and strengthening...



Forecast track shifted left a bit more, more of a threat to Palm Beach County and Martin county. Still could turn north, but that is getting less likely. The new NHC forecast track does take it up the peninsula after it makes landfall, however.

Hurricane watches are now also up for parts of the Florida west coast.

You should not focus on the exact track within this map, the storm is a large area and the track may be off many miles. All areas in the warning area need to prepare.


more to come.

Original Update
Overnight Jeanne strengthened some, pressure went down to 957 and windspeed went up 5mph. The structure of the storm is still good. This morning's aircraft recon found clouds in the eye, but still a closed eyewall, meaning during today as it moves over more warm water it could strengthen. The NHC even said possibly to Category 4. The current Dvorak T numbers (satellite windspeed estimates) also seem to back up this claim of strengthening. (6.5T)

Jeanne is currently nearing Abaco island in the Bahamas.



However, things that would keep it from that strength are the large size of the eyewall (if it begins to shrink watch out), and some of the dry air around it. Jeanne has been handling the dry air around it ok so far. So the forecast is for a major hurricane landfalling on the east coast. Even though pressure had dropped overnight it isn't dropping as fast now..

The track has shifted a little west. So it includes going up the peninsula... Through Charley, Frances affected areas. The forward speed has increased, and the eye is now visible on the Miami long range radar. The worst of it will occur overnight tonight, but rainbands from the storm will begin this afternoon.

You should not focus on the exact track within this map, the storm is a large area and the track may be off many miles. All areas in the warning area need to prepare.


This track could veer left or right... If if veered left, it would take it into West Palm Beach, and, if so, would bring the worst to the northern part of Palm Beach county. If it veers to the right it would bring Brevard county and Indian River counties into the worst of the mix. The northern half of the storm is the more dangerous (although I still wouldn't want to be in the southern semicircle either) around the eyewall. Recon is interesting though, although they had found pressures around 957 earlier, they haven't reported back as high of max flight level winds which suggests to me that jeanne may be restructuring a bit.

Anyway, since the hurricane center has brought it up, I'd be prepared for a category 4 system striking, and hope and pray for less.

And at this point heed the advice of local officials and listen to local media.
