I won't be surprised to see a WSW jog as that heavier band wraps around the W side of the 'center.' The HRRR has been fairly accurate in suggesting that may well happen...;)

Srain, I swear I was thinking the same exact thing.

Sure looks like this may indeed be a coast rider, at least in the short term. At some point it will kick out to the north, but that could end up being across east Texas. It will be central LA, or further west when it does.

watching TWC just now and it showed a "future track" and to me it sure looks like it heads west along the coast. Now I am but a weather "groupie," but is anyone else seeing the same thing?

Don't know if anyone looked at this HGX discussion yet....

.DISCUSSION...
A QUICK UPDATE OUT FOR THE SHOWERS LINGERING IN THE NORTHERN
COUNTIES AND TO RAISE CHANCES AFTER MIDNIGHT FOR SOME SHOWERS IN
THE EASTERNMOST COUNTIES.

ISAAC MADE LANDFALL IN PLAQUEMINES PARISH ON THE MOUTH OF THE
MISSISSIPPI WITH A WOBBLE TO THE NORTH BUT IS NOW WOBBLING BACK TO
THE WEST AND MAY MAKE ANOTHER LANDFALL LAFOURCHE PARISH.

MAY BE UPDATING AGAIN LATER THIS EVENING BASED ON ISAACS MOTION
AND LATEST RUNS THAT BECOME AVAILABLE IF THEY HAPPEN TO TREND
WEST.

I saw that too but they said it will go off to the north. Hurricane Central said it is moving NW. They said advisory shows due west motion since 7:00, but the official track is NW

Eventually heading off to the north is correct, but when is the question. They are wrong about its current heading. No way is it NW.

Dont think he will make it to TX, but every mile he gets closer and closer to us, the more we will feel! I remember this morning hearing we wont be feeling any effects...well that changed throughout the day...according to QPF 2"-4" of rain now for BPT area.

I don't see any westward movement what so ever. If anything a slight movement to the northwest but more than likely dang near stationary. I've looked at 5 different radar loops and none show a westward movement.

Who knows. But HGX mentions in their discussion...

The NHC doesn't all of a sudden change directional heading based on short-term wobbles or perceived movement. The heading/movement is blended. Last night was an example.

Next complete advisory is out at 10.
