WWL is saying that 450,000 people in southeast Louisiana are without power right now. I've heard some rather dimwitted people in my neck of the woods crowing about the "boring" hurricane or complaining about the lack of action in Alabama. Such reactions only prove their ignorance and lack of empathy. A hurricane is only boring if it doesn't come knocking on your door. End of story.

The impressive convection build-up of yesterday evening and last night is proof positive that a well-structured hurricane doesn't need a whole lot of Gulf to maintain itself. I don't see this storm making a lot of northward progress today, unfortunately. Look at that ridge and the dry air! Isaac is bumping himself along a metaphorical brick wall right now.

Don't know if it's just another wobble or the beginning of genuine movement, but to me, the last few frames (GR3) seem to be northward.

Looks west to me. Stair stepping?

Yup, stair stepping with a generally WNW trend over the last 12 hours.

Poor grand isle. It has been sitting in that same band forever.

Agreed. I also heard complaints around my area regarding the "media hype over a tropical storm." Thank heavens for the hype because many people heeded the warnings.

[yzerfan]

WWL says there are now more than 500K people in Louisiana without power.

Looks like a huge Oscillation to me which would cover every direction at some point ...In ENGLISH = Stationary

[Ken711]

TWC seeing the core moving to Baton Rouge over time.

[PTrackerLA]

What kind of conditions can I expect in Lafayette this afternoon/tonight?

[GCANE]

Core is sinking and a boundary layer inversion is setting up.

What's this mean?

[loro-rojo]

TWC is reporting that some NOLA parishes are flooded and that people are stranded in their roofs waiting for rescue.

[mutley]

TWC seeing the core moving to Baton Rouge over time.

Looking at the setup below, I have to wonder.

WHEN?

[Nederlander]

Don't know if it's just another wobble or the beginning of genuine movement, but to me, the last few frames (GR3) seem to be northward.

Movement is WNW...

Is isaac going to stay south of lafayette?

Possible but I highly doubt it

What kind of conditions can I expect in Lafayette this afternoon/tonight?

Conditions will begin to deteriorate this afternoon and tonight with TS force winds and possibly heavy rain. A lot depends on how far west Isaac gets, but be prepared for strong TS winds.
