Hurricane Amanda was the first recorded Category 5 hurricane in the Eastern Pacific, and the strongest ever over the Central Pacific, breaking the record set by Ioke in 2006. The second storm of the year, Amanda formed from a slowly developing disturbance well to the south of the coast of Mexico on 16 May. Thereafter, the cyclone gradually intensified into a hurricane, before undergoing rapid intensification to Category 4 strength. Strengthening slowed thereafter as the cyclone was plagued by wind shear; however, Amanda reached Category 5 strength twice before crossing the IDL.

Origins

The tropical wave that would go on to become Amanda left the coast of Africa on 1 May 2020. Due to the presence of high wind shear over the Atlantic, the system was not monitored by the NHC for development. The wave passed westwards, and entered the Eastern Pacific late o May 9. At this point, the NHC began tracking the system on the 2 day outlook due to the forecast or a favourable environment and significant model support. However, dry air interfered in the development of the tropical cyclone, and the disturbance could only slowly coalesce. Finally, the disturbance coalesced enough for the NHC to issue advisories on Tropical Depression One-E at 0000 UTC on May 16.
