More west shifts

Fwiw the 12z GFS shows some areas in southeast Texas getting 40+ inches of rain...., take that with a grain of salt of course

What a good site to see the latest models?

[TexasBreeze]

Forecasting the track of this system will be a headache. It could go west or go se or even northeast after landfall. Steering collapses and the system could meander anywhere unpredictably.

Not a likely solution. Steering breaks down along the Texas coastline. The CMC has a strong ridging over the gulf that pushes west.

[mcheer23]

CMC which was consistently near Matagorda, shifted down south the past 2 runs..now the NAVY model who was consistently near Matagorda for the past several runs has shifted down south ...hm. Can't wait for EURO.

Was supposed to head to Bolivar this weekend (VRBO rental), anyone think it would still be ok to head down and ride out the storm?

Not a great idea.

There are two ways off the Bolivar peninsula: the ferry and highway 87. The high tides/storm surge will shut down the ferry and flood highway 87 long before the storm makes landfall. Let me emphasis this. I've driven the beach (4x4ing) from Surfside in Freeport to Sabine Pass on LA border. Bolivar is basically sea level and highway 87 floods at the drop of a hat... especially at the eastern end where it connects with mainland. The ferries are low free-board boats that operate only in good weather and good seas - they shut down as easily as highway 87 floods.

Which means you will be trapped on the peninsula. So if the storm intensifies (and it may, storm intensity is more uncertain than storm direction) and makes a bee line for SE East (which intensifying storms are want to due - shift right/east) and you decide you no longer want to ride it out... well, sorry, too late, your trapped. The only way off is being swept out in the the sea... the third way to get off the peninsula.

Honestly, a quasi barrier island like Bolivar is the last place you should think about heading in the face of a tropical cyclone approaching Texas. You do not want to be here during a storm:

Euro with a pretty significant shift west as well. Man I would have to be the NHC trying to forecast this. Extremely complicated set up to pinpoint a location.

[snowman65]

Something else to be thinking about if you live along the Tx/La border (like me). If we get all of this rain they are projecting, AND they get a significant rain up around Toledo Bend, the Sabine River Authority will be opening flood gates to release water from the lake. The lake is only 12" low right now. Alot of people have still not recovered from the flood back in March, 2016 when they had the big release. I can only imagine what would happen should they have to make another large, extended release to go along with all of the rain that is expected. It could be one of those "pack and never return" situations..

Anyone have the EURO?

As a complete novice, just looking at the visible imagery, this thing appears to be beginning to have influence over the entire southern Gulf. Cloud circulation is far, far outside the center of the low pressure.
