Up from 20%

A weak low 470 miles south of Honolulu, Hawaii continues to
produce disorganized convection. Development, if any, would be
slow to occur as this area slowly drifts west.
* Formation chance through 48 hours...low...near 30 percent

I'm not saying they don't but that shouldn't be a factor when determining an upgrade.

Doesn't mean they should shove it to the side the same way the IMD and the JTWC do with certain systems. The NHC does not miss a thing.

I believe they are also short staffed there. They are not a stand alone office, but instead are a part of the WFO Honolulu office

Their headquarters are located in the NWS office at the University of Hawaii. They rotate 4-5 forecasters. Shouldn't be hard to for a small write up on a storm headed OTS.

T2.5 and a POD of 30 percent. Eeek. This has been a tropical cyclone for about 2 days now. I hope it's given a proper reanalylsis, especially since it has appears to have reached TS intensity. It would be an understatement to say that the TWOs issued on this have been seriously underdone.
