When you look at this map it appears that the storm would move NNW according to that map,but I saw the west wobble.

[toad strangler]

Isaias is about as disorganized a hurricane as I've seen in a while. Hurricane winds only in a small area NE of the center. Center on the western edge of convection. Max wind west of storm only about 60 mph 35-40 miles NW of center. TS winds extend only 40-60 miles west of the center. Terrible satellite presentation. Shear quite evident.

truth

Doesn't look like a hurricane at all. On presentation itself it looks like a depression at best. Dry air and shear knocking the teeth out of Isaias.

A few showers coming on shore south Florida now. Is it possible the environment moistens up?

And to make it worst the dry air being entrained into it causing all that cooling downdrafts on the NW quadrant.

The lowest was 985.1. Not sure why they went almost 10 mb higher.

[Highteeld]

978 extrap (this censor has been generous last few days)

Miss Piggy:

973 mb.
Some one has a bad calibration.

[NDG]

2 dropsondes were dropped in eye by AF recon, one showed 991mb and the other one 987mb, but the VDM shows 993mb.

[Ian2401]

getting very close to landfall in Andros

[Chemmers]

Is the 978 mb true?

[GCANE]

I don't see any weather stations on Andros.
Anyone else see one?

[Highteeld]

Is the 978 mb true?

highly unlikely to be accurate

[lhpfish]

Looks like it’s going right over the middle of Andros

[GCANE]

Is the 978 mb true?

Obviously a calibration error in the instruments somewhere.
Would be good if a surface ob would verify.

[SFLcane]

Good Morning All. Woke, saw the storm, ewww, horrible satellite presentation. Stay safe ya'll

Ah.. going back to sleep. I will enjoy my breezy rain day conditions.

[StormingB81]

I’m here in coastal Brevard ready to chase from my backyard lol don’t mind my post because if you’re nervous mine will make you freak out lol...bring on a hurricane it would be the most normal thing to happen in 2020 lol
