I don't see anything I'd call donuts, but they are keeping off-shore. Notice the shoreline.

Yeah.. Matagorda will get the brunt of the surge and winds and rain...

It does appear to keep jogging further and further N though. It's radar watching time now so we will see where it eventually ends up.

They might bump it up 5mph, but I think Harvey running out of GOM real estate to do much more...

It is definitely up to a C3, just give the NHC time to make it official.

I thought from the beginning of intensification yesterday with all the models, that 940 was probably the lowest he would go. My estimate may have been high.

I'm no pro-met, but a 125 mph and 935mb peak seems very attainable to me.

Me either but I'm not sure he's got much more time or ocean real estate to help achieve that....
