Tropical Storm Cristina Discussion Number  22
NWS National Hurricane Center Miami FL       EP052020
500 PM HST Sat Jul 11 2020

Cristina continues to maintain a broken ring of convection around 
its center, and there has been little change in either the 
organization or the various satellite intensity estimates since the 
last advisory.  Based on that, the initial intensity is held at 50 
kt.

The initial motion is westward or 270/12.  The track forecast 
guidance remains in excellent agreement that Cristina should 
continue generally westward through the forecast period on the south 
side of the subtropical ridge.  Only minor adjustments have been 
made to the previous forecast track, and the new forecast is in the 
middle of the tightly clustered guidance.

The cyclone is over sea surface temperatures near 23C, and the 
temperatures cool along the forecast track for the next 60 h or so. 
This should cause Cristina to weaken to a depression in about 48 h 
and degenerate to a remnant low shortly thereafter.  The latest 
global models forecast the remnant low to weaken to a trough between 
96-120 h, and the NHC forecast thus shows dissipation by 120 h.  The 
new intensity forecast is otherwise unchanged from the previous 
forecast.
