#NOAA42 #Isaac: On east-west pass, lightning display here. Winds at flight-level from east, suggesting flight-level center is south of us.
These poor guys still can't pinpoint the center.. Going to be interesting to see what the 0z runs initialize with
I've heard in the past, that if lightning is present during a hurricane/tropical storm..it either means its intensifying..or actually diminishing in intensity. Not sure how reliable that is, so maybe someone with more knowledge than I have, can address that issue.
Yes this is somewhat true.. but you have to have one main surface center... and it stacks up through the atmosphere. With Isaac right now, we have a disorganized system, mainly due to easterly winds i think... not really "dry air"... Lightning occurs mainly in Tropical Systems when you get "Hot Towers"... also known as Thunderstorms.. which usually with a High built above a hurricane, these towers can shoot up high and there's "wind" causing the lift, motion, etc. Isaac is not really intensifying ATM, based on what i see.

Hey Blinhart - I'm south of you in Vermilion Parish. Not liking the idea of a storm, but hey- that's part of living where we do. Just be prepared and watch.

We know all about the high building into the southeast. You have mentioned this 1000 times tonight.

Re: ATL: ISAAC - Models
Just looking at the core blob of convection, this appears to be moving somewhere between 270/280 in general with the heaviest convection further south. Unless it either starts a quick turn NW, and/or reforms heavy convection further north, it will miss Hispanola all together............by a decent margin.
Like you said many times before Aric, look at the movement of the blob in general.

Re: ATL: ISAAC - Models
Guess I am a little anxious to see what the 10pm updated track shows... my house is about 6 miles inland on the AL/MS state line in Grand Bay. Not in a flood zone but still wouldn't want a major bearing down on me. I know what Frederic did to this area back in 1979, taking a similar path.

Lots of anxious folks for sure all along the gulf coast. All we can do is be prepared and deal with whatever comes our way the best way we can.

Re: ATL: ISAAC - Tropical Storm - Discussion
question..
If the 5 pm advisory said the llc was to be at 16.6 in 12 hours, but the center is already at 16.5 as per recon findings tonight also heading WNW/NW might this not shift the track back east a bit?
