CURRENT ADT Analysis Discussion

2.3 CI# is good , But considering the Raw T# of 3.2 . , And has 0 MSLP.
Note the following anomalies in the Cloud reads, Center Temp : -16.9C Cloud Region Temp : -41.0C ~ Rapid Peak ?
Also Constraint Limits : 0.7T/6hr ~ Not alot holding it back from getting stronger , In the near future.
No Flags are on either
Looks healthy

Recon is finding winds to support these T#'s and estimated winds...in fact, it looks like the estimated winds on this might be a tad low.

2.4 2.5 3.0 ~~ Good healthy growth in the CI#


Center Temp : -18.7C Cloud Region Temp : -38.4C

Continual Growth

I think you are right in that the ADT Estimate seems to be a little to low ,
And has the center to close to the coast , I think the actual center may be further off the coast

The MSLP Adjustment is off

You are very correct
