Looks like we have rain headed our way...hopefully it won't be too much of a good thing.

Alot of activity happening to Hermine who was suppose to move straight into Mexico. Still could but with the cone shifting. Interesting to wake up too and to watch today.

Position between the 4 and 7 am advisory -

4 - 21.6N 95.0W

7 - 22.4N 95.3W

We won't get a exact fix until recon.

7 - 22.4N 95.3W

We won't get a exact fix until recon.

When is Recon flying and the motion looks to be a little more north then west.

[Met Tech]

Do they drive around Alaskan highways at extreme high rates of speed testing some weird looking contraption on the top of their roof?

I sure hope that highway event isn't the only thing that contraption sees this year!!

Have to double check but it should be early this afternoon and in time for the 4pm package.

Heading - Agreed, still basically a northerly heading. The general turn to the NNW should evolve over the next 12 hrs.

lol. I was fixing to tell him to overnight it and I could give it a test drive. Of course this pesky thing barely has that much time.

Speaking of which. I need to get with ya about possibly building me one or helping me out in building one. I know you touched on how to do it in the chase thread but wasn't sure if you had already got a patent on it.

One of those off season things to do.

I am having a feeling that we are going to see more rain then we are asking for...That moisture in the Gulf looks pretty ugly on the radar...

[MRG93415]

I see that harris and waller is not in the flood watch, is that gonna change you think or do you think we wont get much rain.

[srainhoutx]

I see that harris and waller is not in the flood watch, is that gonna change you think or do you think we wont get much rain.

That may change later. Houston/Galveston NWS said this morning that it may have to be shifted further E later today after evaluating new data.

[ticka1]

I think alot of it depends on how much rain we get is where Hermine makes landfall. NHC has it for 1:00 a.m. Tuesday - which is tonight. Not a good way to start the work week tomorrow - with lots of rain - if we get it.

[srainhoutx]

Looking more impressive with each new sat image...

[ticka1]

I have to agree with you Srainhoutx. Glad I have no plans today and can watch TS Hermine .....

[srainhoutx]

These are a couple of hour old now, but you can see that it was organizing rather well at that time. It appears that convection on the Western flank has increased greatly since that pass. Hopefully the next pass will catch most of the storm...

[srainhoutx]

CDO (Central Dense Overcast) is developing rather quickly now. Hermine is located in an area of the Gulf that is virtually untouched since Alex. I would not be surprised to see this ramp up rather fast.

[Portastorm]

A quick scan of morning forecast discussions out of NWS South Texas offices looks like 6-12 inches of rainfall for the Valley and 5-10 for inland areas along the path of Hermine, including my area of AUS/SAT.

Those of us who wanted rain ... well, looks like we're going to get it and then some!

[srainhoutx]

RECON will likely find a very impressive system when they arrive...

Edit to add that RECON is airborne and should arrive in about an hour and 30 to 45 minutes...

[Portastorm]

Hermine appears to mean business and is definitely ramping up quickly. Last night I would have scoffed at the suggestion that this storm could be close to a Cat-1 by landfall. That doesn't appear to be so far-fetched as this point.

This one looks like a real flood threat for us in south Texas.
