Recon has shown that FL winds are having trouble fully mixing down, and there’s a region of increased winds on the east side of the storm. Either it’s a double wind maximum, or the wind field is very oblong.

What is going on here?? To me, not knowing anything it looked like Delta formed a second/different center/eye

I realize that likely isnt possible. Could someone explain what Im looking at? Never tried posting a GIF so added the link also

Looks like the center was moving NW and refired convection. You usually see that with weaker storms where the centers follow or chase convection. Maybe it was just a new burst as the center moved

Large jump in rain rate.
Recon now reporting 54 mm/hr.
Latent energy exchange kicking into high gear.

Delta doesn’t look too photogenic this morning, not that it ever did. Probably won’t intensify much more, if at all. Still will be a big surge producer and a wind maker, but if I’d had to guess a landfall intensity I’d go with anywhere from an 85mph Cat.1 to an 100mph Cat.2 in SW Louisiana. Fortunately it won’t be a Cat.4 like Laura was six weeks ago.

The extent of hurricane-force FL winds to the east could be...problematic. Those translate to TS winds at the surface and are extending the TS wind field, meaning more surge on the E/NE side.

That 36 nm eye could contract a bit and pick up the wind velocity. The meso on the north eyewall is pretty impressive, with lots of lightening.

Also glad it should be moving at a good pace and not leave so much rain behind like sally

This pass through the NE quadrant supports 90-95 kt maximum winds and a pressure of 966-968 mbar.

What is the confidence level for the turn keeping the eye away from Houston?

Latest recon passes showed 965 - 967 mbar central pressure and would be in-line with ~90 knots. I think 95 knots might also be reasonable, but I don't think NHC will do that just yet.

Increase in rain rate to 62 mm/hr.
On target for increasing latent energy transfer becoming predominant.
