ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM Tropical Storm Bonnie Discussion Number 47 NWS National Hurricane Center Miami FL EP042022 200 AM PDT Sat Jul 09 2022 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.
