Deep convection associated with Bonnie has decreased over the past 
several hours, with only a small area of convection remaining in 
the northeastern quadrant.  The various satellite intensity 
estimates are in the 30-55 kt range, and based on these and the 
convective trends the initial intensity is reduced to 45 kt.

Bonnie should continue to weaken as it moves over cool sea surface 
temperatures and as it ingests a drier air mass.  The system is 
expected to become a post-tropical cyclone by 24 h, and the global 
models are in good agreement that the system will weaken to a 
trough by 60 h.  The new intensity forecast has some minor 
adjustments from the previous forecast.

The initial motion is now 280/17 kt.  Bonnie or its remnants should 
move quickly westward in the low-level trade winds until the 
system dissipates.  The new forecast track is in the center of the 
tightly-clustered track guidance.
