FORECASTER PASCH

[Innotech]

she weakened overnight. I saw what looked like an eyewall replacement last night, and I figured we'd see a little weakening this morning, before Ivan spins back up to Cat 4 and possibly beyond. sure enough, winds are down, and pressure is up.

[canegrl04]

Ivan is suppose to regain cat 4 status over the next couple of days

[Lowpressure]

This one will keep you very busy cycloneye. Be safe and thanks for the constant high level service you provide. The islands are in serious situation with Ivan.

[Tip]

Early vis pics show a poor signature for a strong CAT3. I'm not sure he's that strong.

[Aquawind]

Sorry been a little preoccupied with things around here..

How fast was Ivan traveling when it developed and when it bombed yesterday? Geesh 23mph is just like the good ole days when things could barely organize..Looks like it might even be speeding up in the forecast..

Gimme the Ivan speed lowdown somebody..

20-21 mph. He's been moving that fast since he formed.

[Aquawind]

Just Wonderful..Thanks Brent

[rainstorm]

i said in chat last night ivan would weaken. i am personally hoping ivan speeds up even more. all of us agree the states should not get hit again

[AussieMark]

he does that by moving quickly .

Hate to see what would happen if he was slow

[rainstorm]

lets see what the recon finds

[Thunder44]

I don't think speed is the issue with this storm. I think it moving north of South American now, and it's preventing inflow on the southern side of the storm.
