Ivan with Double Eyewalls? Weakens a bit

11PM
Ivan is holding at a category 4 level for now. The track remains very similar to the 5PM. The current forecast track has it skirting along the west coast of Florida into the big bend, but again even a slight error really can change this.

The good news is that shear is expected to develop so we may have another storm that weakens right before any landfall, but the otuflow is so good right now, it may not weaken as much as I'd hope. Intensity forecasts are by far the most prone to error, and this will have to be watched.

Original Update
Hurricane Ivan is back to Category 4, after an impressive run earlier today as a category 5.

It's expected to fluctuate in intensity, and again, the forecast track has moved a bit to the left. However the longer term forecast is still quite uncertain. It will be interesting to watch the model trends.

It may be going through a double eyewall cycle, which would explain the weaker winds. This would allow it to restrengthen once again once this cycle is over.

Also, Tropical depression 10 has already came and went, it's now has dissipated.

More to come later today.

** SITE NOTE ** Although we are working on improving the site hardware and bandwidth (thanks to donations and help from others), we are still using the old system currently, with slight modifications. Therefore the site may go down from time to time, although not for very long. We are continually working on improving the response without removing usefulness. We have new hardware on order and should be in sometime next week.
