[Steve]

I've never been so dead center in such a tiny little cone. I'm as ready as I can be. I have a grand toddler in the hospital set to be discharged tomorrow. I have to go to work in east Biloxi in the morning to finalize preparations. East Biloxi floods in an average rainstorm. I hope it doesn't come in early.

Be careful HeeBz. I think the timing is about 11 or midnight if it hits Harrison county. That’s not to say there won’t be bands 4, 5, 6 hours ahead of landfall. It’s a small storm for sure, and it’s depicted to be that by most model simulations. But still. Power lines, tree limbs, ponding, some surge in the rivers and back bay should be expected with Gordon if it hits you guys.

[Steve]

Yeah, it's a mess right now. Unless something changes, I don't see this strengthening much more.

So far the mesoscale depictions have a decent looking TS for y’all tomorrow around landfall.

The High Pressure to the North moving further South is not likely to happen, correct? This would be the least likely scenario, I would think.

Extremely unlikely. Just because folks throw out alarmist "what if" scenarios, doesn't mean there is any science behind it. Model output and official track forecasts have been quite consistent on the forward speed/direction for days now, and Gordon is behaving as forecast in this regard.

I'll do my best, Steve. I hope to get settled in somewhere around noon. I still feel this could get stronger overnight. Will have to see in the am.

Pressure has risen to 1007

[galaxy401]

If Gordon becomes a hurricane tomorrow, is it possible the pressure can still be over 1000. Background pressures seem quite high over there.

[MississippiWx]

Recon is going to come in for at least one more pass soon. We will see if the convection over the center has helped lower pressures again.

[MississippiWx]

If Gordon becomes a hurricane tomorrow, is it possible the pressure can still be over 1000. Background pressures seem quite high over there.

I doubt it would be over 1000, but it could be a good bit higher than normal. The background pressure is certainly very high thanks to the stout ridge over the East Coast.

[Blinhart]

What is the possibility of this having a CoC relocation further SW???
