Interesting discussion about the Swirl over the mouth of MS river becoming the dominan CoC after it moves inland.
Tropical Storm Cristobal Discussion Number 25
NWS National Hurricane Center Miami FL AL032020
400 PM CDT Sun Jun 07 2020
At least two low-level vortices have been noted rotating
cyclonically within the broad inner-core circulation, with one swirl
located southeast of the advisory position approaching the
Mississippi Delta and the other swirl located inland to the
northwest of Grand Isle, Louisiana. The larger swirl in the
southeastern quadrant will likely become the dominant low-level
circulation center later tonight after that feature moves inland
and frictional convergence tightens up the broad inner-core wind
field a little bit. The initial intensity remains 45 kt based on
data from surface observations and NOAA Doppler radar velocity data
from Slidell and Mobile, along with a satellite intensity estimate
of T3.0/45 kt from TAFB.
