Yeah I posted it earlier in the general thread. Though high shear, I wonder how much more this can intensify, and if it does, how would that effect its outcome here.

Why is this thing so sluggish?
-
Not much to move it. Once the upper-level trough starts to close it, it'll shoot off to the northeast.

Tavores, here's a better version of the NHC track map. You had the 5-day cone turned on earlier, and I've turned it off to only show the 3-day cone here to illustrate the warnings better. Andrea is just going to be a big flood threat with some severe weather possible based on what I see. It's not going to have much warm water or light wind shear to allow the winds to increase, so NHC only has 45 mph winds at most in this forecast. Hope everyone in the Southeast takes appropriate actions.

Sidenote: Score 1 to the GFS for sniffing this puppy out 2 weeks in advance. :thumbsup:

I'm tellin' ya. You'll be surprised how often the GFS can pick up on tropical disturbances. Not all the time it is right, but most of the time it is. :thumbsup:

Agreed. I notice that quite a bit.

Apparently a lot Craig, I woke this morning to a 60mph TS with a 997mb pressure. :o

There were 5 different tornado warnings sparked off within an hour between 2:30am and 4:00am this morning by Andrea for Hillsborough and Manatee Counties. And here's how she looks right now..
The larger box is Tornado Watch #242, in effect until 11:00am this morning

What a wild time to be in FL right about now. All FL folks here and in general I hope are staying safe and out of the water although that should come with common sense not to be out there anyway.
I'm still impressed at how rapidly Andrea got itself together overnight into today. RECON did find max outbound flight level winds as high as 71 kts (80 mph rounded off).

Whoa hello

...ANDREA ABOUT TO MAKE LANDFALL OVER THE FLORIDA BIG BEND... ...RAINS AND WINDS TO SPREAD NORTHWARD ALONG THE SOUTHEASTERN U. S. COAST TONIGHT AND FRIDAY...
5:00 PM EDT Thu Jun 6
Location: 29.5°N 83.4°W
Moving: NE at 17 mph
Min pressure: 993 mb
Max sustained: 65 mph

Wow, Andrea made landfall not far from where I said it would a couple of days ago. (Near Cross City, FL)
-
Andrea was just declared post-tropical at the 5 PM EDT advisory as it has caught the baroclinic zone of an upper level trough to become extratropical. However, thanks to the new rules that came from Sandy last year, NHC is going to continue issuing advisories on Andrea until it no longer poses a threat to the East Coast. The winds are only at 45 mph, but those winds can only be found offshore or along the coast. Thus, severe weather and flooding are the primary threats to watch.
-
Torrential downpours here. Waterspout over the water just south of here. :thrilled:

I cringed when I first saw this but we only ran into heavy rain from Tallahassee to I-75. All is well now. :thumbsup:
-
There was Severe Flooding in Fall River, MA last night into this morning. Alot of cars were either stranded or pulled over throughout the side streets and RT 24 and I-195.
-
NHC has issued the final advisory for Andrea. I hope everyone along the East Coast is okay.
-
Well, goodbye Andrea until 2019. Unfortunately, this will not be the last storm of the 2013 Atlantic Hurricane Season, but hopefully, it will not be as active as the prognosticaters are saying. Maybe an unexpected El Nino will show up, or maybe there'll be more shear in the upper levels than expected.
