ATL: DOLLY - REMNANTS - Discussion

[USTropics]

WPC 5 day total precipitation:



NHC stated in the discussion there could be a possibility of 10 inches in some locations.

Recon is finding a weak LLC down near 21.8N/96.4W. The northern center may be dissipating. Dolly could have several weak centers rotating around a broad low. Pathetic-looking storm...

Just saw the NHC public advisory putting the center at 22N/96.5W. Recon did not find a center at 22N, though. It is definitely south of there:

Vortex says 21.7N / 96.4W. Northern center is dissipating.

Based on the SFMR readings (some reliable in the high 40s) I would go with 50 kt for the current intensity.

Yet another center found near 22.1N/96.8W - that's 33nm NW of the first center found near 21.7N/96.4W. No way it's the same center unless it's moving NW at 30 kts. Looks like multiple weak vortices. Another one is dissipating up near 23N.

Yet another center near 21.5N/96.3W. They're all over the place!

Interesting to see what they find in the NE quad under the convection if they make it there.

[ScottNAtlanta]

It sure looks like the center is reforming SW. Convection is wrapping around it too in that area.
Recon is finding lower pressures than at the vortex NW of where the last VM was sent...I think the center is somewhere in the BOC...pick a place...any place.

She's keeping her options open

Too many centers to keep track of. Just move ashore, Dolly! Euro indicates something interesting in the Gulf at day 10.

Not too much time before landfall, but appears to my eyes that shear has definitely decreased. Notice storm tops now beginning to move in anticyclonic nature north of the "center"

[Sanibel]

The convection looks like it was getting ready for business. You can see a vortex vigorously spinning while diving SW into Tampico.

Tropical Storm Dolly is looking much better organized this evening, a testament to lower shear as the storm approaches the Mexican coastline. Based on satellite presentation alone, I'd estimate winds have increased to around 60 mph.

The center reformation is also going to allow for more rain to impact this area. Earlier, the NHC was anticipating 10 inches in some locations. They have upgraded that to 15 inches now:

The primary threat from Dolly will come from heavy rainfall, with
precipitation totals possibly approaching 15 inches in a few
locations. These rains will likely cause flash flooding and
mud slides in regions of mountainous terrain. This threat will
continue even after the center moves inland.

[CrazyC83]

Looks like it is making landfall. Based on SFMR readings from earlier in lighter rain, I would agree with a 50 kt landfall intensity.

Agreed a very professional discussion. Some snippets:

Tracking the center of Dolly this afternoon has been, to say the
least, challenging.

With the center relocation, it is extremely difficult to estimate
the initial motion, but my best guess is 270/10 kt

[CrazyC83]

I can see the center on radar now...

It's getting very close to landfall, might make landfall tonight.
