DISCUSSION
-----------------------------------
Deep convection associated with Rene appears to have lost some
organization overnight.  Although there have been several pulsating
bursts of convection overnight, the convection that was persistent
over the center during the evening is now confined to the southern 
portion of the circulation.  A blend of the latest subjective and 
objective satellite intensity estimates yields an initial intensity 
of 35 kt, but this could be generous.  ASCAT data later this 
morning should help to determine if Rene is still a topical storm. 
Mid-level dry air appears to be the primary reason why Rene has 
struggled to strengthen over the past few days, and although the 
shear is expected to remain low today, the dry air is likely to 
prevent strengthening.  On Sunday, Rene is forecast to approach an 
area of strong west-northwesterly flow aloft, and this increase is 
shear is likely to cause the cyclone to weaken.  Most of the global 
models continue to significantly weaken Rene early next week, and 
both the ECMWF and GFS suggest that the cyclone will degenerate 
into a trough of low pressure by days 4 or 5.  The NHC forecast 
continues to maintain Rene as a tropical cyclone throughout the 
forecast period, but if the current trends it is becoming unlikely 
that Rene will survive as a tropical cyclone for the entire 5-day 
period.
