I told you so. No trip to IAH for this sucker. Next....

Hi Res satellite imagery loop suggests Alex continues to organize. A bit of dry air to the SW, but convestion ramping up near the center on the North, East and South simi circle. Would not be surprised to see at least a Cat 2 at landfall.

What is the trough's current status?

Some clues from WV Imagery...

Thanks again for bringing up the heavy rainfall concern singlemom. We appear to be on the dirty side of Alex with landfall expected to our S and W. The NE quadrant usually will contains a tremendous amount of tropical moisture that can feed into the area E of where landfall occurs. That can persist for several days as the moisture feed off the Gulf continues and relaxes. I suspect that even a N MX landfall will allow for a chance of tropical showers and storms throughout the weekend. If Alex tracks closer to our area, that opens the door to many other issues. Needless to say we need to keep an eye on the situation as it unfolds.[/quote]

Thanks again, Srain, for the spot on analysis and response. That's what I've been wondering about and it really hasn't been discussed that much as this has been one odd storm. Byte, I've been concerned about the points you've brought up this morning. I love the insight the night crew brings me. This is one of the best boards out there and I sure have appreciated it.

Speaking of rain totals, HPC has upped again total rain amounts for SE TX, especially along the coast..

How much confidence do you have in what rain we will get here in SE Texas?

If those rain bands could lift just a few miles, my area would be getting in on some rain now...But those bands are looking pretty impressive SW of here.....

Alex STILL not a hurricane with the 11 a.m. advisory.

Here's a silly question:

I keep looking at pics like this one, and I keep seeing this rather large area of convection to the northeast. With all the focus of where Alex is going to land, what about that rather large area to the Northeast? Where's that going to set up shop? Or is *that* the area that is supposed to make the left turn *any time now*? Inquiring noobs want to know.

Well Alex is so gosh dang big, that low pressure is just maintaining the size?

I was about to mention those 55 kt flight level winds with the northern outer band.

Possible center. Waiting on vortex message.

What of that northern piece of Alex? Will it come back and consolidate with the rest of the system?

RECON may have turned NE prior to center as well.
