Dang, that's one big storm... even if it comes in at Matagorda - it seems Houstonians are in for a lot of wind and rain...

Does look like it will take up most of the gulf in cloud cover, especially when it reaches it's maximum forecast intensity. The eye to Orlando is about 400 miles as the crow flies, so Ike looks around 800 miles wide.

Eclipse over

Cloud tops much colder near the core on the post eclipse 1KM GOES 12 than pre, and the dry air is clearly being overrun.

question - how can Ike be so big, look so impressive, have a low pressure, and still be just a mid-level Cat 1? Not that I'm complaining in the least, it just doesn't seem to add up...

[Cyclenall]

962 mb extrap shows the pressure is dropping at a good rate. How many category 1 hurricanes have had a pressure that low?

[Chris_in_Tampa]

Could the pressure gradient between Ike and the ridge possibly be contributing to the increased winds on the NE edges of the storm?

I am sure that as he gets over the affects of Cuba giving the really low pressure winds will start to ramp up here through out the day today.

962 mb extrap shows the pressure is dropping at a good rate.

Lowest extraps from last 3 passes:

03:04:30Z 966.9 mb
05:53:30Z 964.6 mb
07:08:00Z 962.4 mb

2.3 drop in 109 minutes, then 2.2 drop in 77 min

Afaik, the size is the reason why he isn't that strong...It's about the gradient between two pressures... The one with the tighter gradient is the one which will have the stronger winds... The difference in pressure within a small distance is greater with smaller systems, and thus have stronger winds (If the storm was small with this pressure I'd assume the winds would be a lot more)

What the heck is with the teeny tiny eye on IR? Something bizarre about such a small pinhole in such a sprawling, disorganized looking system.

Seems like those winds are starting to respond to the pressure

Code: Select all

Level                 Wind Direction             Wind Speed
962mb (Surface)     55° (from the NE)         91 knots (105 mph)

Is that FL or surface winds?

[xironman]

It was from the dropsonde, maybe the instrument was messed up. It does seem a lot higher than surrounding area.

[bob rulz]

If those are really the winds are we going to see a special advisory or will they just wait until 5am?

[Hockey007]

Ike is gone!!!! It's over, no more evacuations, it dissipated!
Yeah, this is an error on the satellite, the newer images actually have ike in the picture.

[xironman]

From the VDM it looks like they disregarded it.

[Hurricanewatcher2007]

Ike currently takes up about 1,000 miles from its furthest north point to its furthest south point. and that may be off a little because some of Ike is off of the map that I am using.
