[Hurricanewatcher2007]

Going a ways into the 970s I would say since winds are still 80+ kts with that 980mb pressure

THey are not at 1500 ft are they ??

No, more like 3000

Meters.

They are at 700 mbar / 10,000 ft which is the standard height for flying hurricanes. They fly 850 mbar (and sometimes lower) for tropical storms.

Isnt that massive tail to Ida's east going to create rain for Florida as Ida heads north?

[cycloneye]

12 CMC is intense at landfall in Louisiana.

[lonelymike]

Need to note that hurricane force winds are only out to fifteen miles. Enough to blow Ivanhater and Dean4storms out to sea but nothing else.

[PTPatrick]

not get a wobble war started, but it looks to be getting a little N of forecast points again. Probably will shake back out soon. Ida must have gotten a few drinks in Cancun. Its a shame hurricanes cant just move in a straight line.
