4AM CDT HPC advisory on Arlene's remnants

[Coredesat]

Eh, I figured there are probably a few people here who do follow the HPC advisories. I know I do, so I decided to go ahead and post this. It includes rainfall totals from areas of Florida affected by the heavy squalls to the east of Arlene's center.

Anybody catch the error in the pressure?

30.07" or 998mb.

Well... 998mb is actually 29.47". 30.07" is actually 1018mb.

Anybody catch the error in the pressure?

30.07" or 998mb.

Well... 998mb is actually 29.47". 30.07" is actually 1018mb.

BTW, I should say that Arlene is really "29.47 inches or 998mb."

[Coredesat]

I just noticed that. What's even worse is that they repeat the error when they repeat that information at the end of the advisory. It will probably be corrected in the next advisory, if there actually is one (there probably will be - HPC's maps show Arlene as a distinct feature for at least the next 48 hours before it is absorbed by a front).

I don't expect there to be more than maybe two more advisories, though.

30.07" or 998mb.

Well... 998mb is actually 29.47". 30.07" is actually 1018mb.

Good catch, I missed it. I think most of us just breeze through these at this point inland. I bet if she were cranking up in the Gulf and they made that same error, this board would have lit up like Christmas.

I don't expect there to be more than maybe two more advisories, though.

HPC says they will issue advisories as long as the storm is a flood threat, which could be a couple days. However, the discussion leads us to believe that this won't be a big rain producer.
