Lol these models... 18z GFS shows Marco as a naked swirl riding the Louisiana coast into southeast Texas similar to last nights EURO run.

The GFS also has Laura tracking further w thru hr 90. Looking closer to central or w la.

I have a feeling this will be a close close call

Yeah I don’t think we’re clear of Laura.

Yes. A weaker storm would go more west.

I dont understand this. If there is a high pressure system to the east, why would a weaker storm go more west? I always thought stronger storms get pushed by ridges more than weak ones

Stronger storms are more influenced by the steering currents than weaker ones. They’re basically a lot more sensitive and can feel ridges/troughs from miles upon miles away. Something like that.

Yep - Stronger storms have high pressure overhead, which bounces or feels it's way around ridges and towards troughs. A weak, sheared off system is more affected by lower altitude winds.

Having said that, I would not place my bets yet either either Marco or Laura yet.

When is Laura expected to clear Cuba? I imagine it’s going to be hard to get a good read on Laura’s track until then.

Monday afternoon.


Looks like the GFS 18z run shifted west some.

Marco is still projected to turn west after landfall. Have not given up yet, although a bust is probable.

If Marco turns 100 miles earlier, we all could get very wet.

...and on cue, there's the GFS shift.

A small margin of error is making a huge difference in landfall location. The models have been like a drunk handling a firehose...

A chuckle before my 6 mile run. Thanks as always to the good Doctor in the house.

I don’t think we’re out of the clear for either system. I don’t really think the models have a good handle on either of these systems.

LOL That's the best analogy I've heard about the models in a long long time. These models have been terrible all year so I'm going to keep watching just like everyone should be.

Well that's intriguing

That was yesterday’s

This is from yesterday’s run! Has today’s started yet?

I wouldn’t be surprised to even see a possible wsw movement with Marco as it nears the coast of Louisiana.

Hmon cat 5 headed to Galveston

I believe these are from 12z today.

If I remember correctly, the hmon has been up and down the Texas coast over the past few runs. It had a Galveston hit at 0z, middle tx coast at 6z, and tx/mex border at 12z.
