they were not fully at operational altitude at that time. was a wind switch from dropping down more.
they are down in the general area now. straight south winds means the center is ever so slightly to the west.

Re: ATL: INVEST 98L - Discussion
Thankfully this cannot get the convection to sustain , although it has been firing all around the center and glad it's short on time to encounter shear to the NW of the system. Hope it stays that way overnight tonight. In reality that's a good bit of time to allow for beach erosion on already hammered beaches.

Looks like we're going to come down to a judgement call by whoever is on shift. Hopefully we can get an upgrade out of this so that (as with TD10) it can go on official record.

Re: ATL: INVEST 98L - Discussion
That's the thing that frustrates me. Having this fascinating long lived feature, worthy of being labeled a depression it seems, documented at all comes down to a subjective judgment call. If they don't upgrade, this goes down as nothing in the books. If there's a closed center (seems to nearly be as per recon) and deep convection (has been for 2 days) it's a tropical depression. They've initiated advisories on much worse lol

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Is it possible they won't do it so that they don't freak out coastal NC? Its close but it doesn't seem like its going to do much (it did quite enough the first time around )

There is no lower boundary for wind speeds in a TD. Technically, they could initiate advisories and call it a TD with 15 knot sustained winds.

The strength of the wind is not a criterion for a TD> however there are likely 25 to 30 kt winds out there in the heaver squalls to the east.
