Tropical Storm Bonnie was a pesky, hard to forecast and preseason tropical cyclone that developed in the southwest Atlantic. Bonnie was responsible for 2 deaths, and $640,000 in damages. Originating from a cut off low near the Bahamas on May 25, the precursor disturbance organised relatively quickly, before becoming a tropical depression on May 27 as the system developed a low level circulation. Moving to the northwest, the system became a tropical storm over the Gulf Stream, besides unfavourable shear, and attained peak winds of 45 mph before succumbing to increasing shear and land interaction as the system neared landfall. Making landfall on May 30 as a tropical depression, Bonnie weakened to a remnant low later that day, before moving back out into the Atlantic. Over the next few days, Bonnie slowly reorganised, and on June 2, the cyclones remains regenerated into a tropical depression, and then, besides hostile shear, took forecasters by surprise and reintensified into a tropical storm the following day. However, after moving out of the Gulf Stream on June 4, Bonnie weakened to a tropical depression, before opening out into a trough of low pressure, which was absorbed by a frontal system over the central Atlantic 2 days later.
