Such is life with tropical systems.

The gradient of "yeah we could use the rain" to "there is a foot of water in my house" can be quite tight.

The slightly cooler feature near the presumed LLC - is that the beginning of an eye feature?

ETA - I meant slightly warmer tops.

It is but I was more impressed by the rebound of the upper energy level throughout the culmination of the wind shear

Unfortunately it still has a solid 36 hours in all likelihood.

Pardon me for not being up on all the jargon and certainly the science, but how does one reconcile the current computer models showing whatever this storm is bending northeast and hitting MS/AL border with the National Weather Service advisory map regarding “landfall” in Louisiana south of New Orleans?

Lots of lightning in it as well. She looks ready to start a run at becoming a hurricane.

Those models are what are used for the next track update at 10 pm.

Having some idea how they make the track forecast, it suggests the track will be farther east at 10 pm with the model consensus shifting to the east.

10 is a track update.

10 am/pm. 4 am/pm. Those are the full updates with a new track.

1 am/pm. 7 am/pm. Those are the intensity only updates.

This needs to be added to the OP. That question gets asked alot.

Computer models run all day. NHC makes their track/intensity forecast updates every 6 hours - 10a, 4p, 10p, 4a (central time).

Much of what the NHC uses for quantitative guidance is available to the public between updates, so we're seeing what they're going to use to make an adjustment at 10p. They will also make their own subjective adjustments, and then they send it out to us.

They're prone to making very subtle adjustments on the track, and that approach typically leads to the NHC being better than any individual model.

If the 10 PM track shifts to BSL y’all gotta teach me how to set up a security camera to live stream for y’all in Gulfport. Then promise to come get me/drop off steaks and propane if I need help.


What type of camera system is it?

Can you stream directly to live streaming sites using the camera’s interface?

Can you remotely access your cameras currently? If not you may need to setup port forwarding on your router to access the camera streams on your DVR.

Are your cameras IP or Coax based?

I'd say so. Northshore won't even feel 3 inches but won't be able to walk for days after 16 inches.



We got 11 inches a few months ago one Sunday evening. Wasn’t that bad. Wasn’t great. Took a day or so for water to recede back to normal.

16” would suck. Especially with storm surge.
