 By 1500 UTC on September 27, the National Hurricane Center declared Bonnie extratropical, since it was losing tropical characteristics. Bonnie re-acquired tropical characteristics, and the National Hurricane Center resumed advisories on the storm by 2100 UTC on September 28. However, post-analysis indicated that Bonnie remained tropical during that time period. Bonnie re-strengthened to a strong tropical storm before vertical wind shear weakened it while approaching the Azores. Shortly before becoming extratropical on September 30, Bonnie passed through the Azores as a moderately weak tropical storm. One location in the Azores reported tropical storm force winds. In addition, one man was killed by a rock fall on the island of São Miguel. No damage was reported in association with Bonnie.
