The National Hurricane Research Project (NHRP) was initiated in 1955 by the
United States Weather Bureau in response to the devastating 1954 hurricane season, which
saw Hurricane Carol
Hurricane Carol
Hurricane Carol was among the worst tropical cyclones to affect the New England region of the United States. It developed from a tropical wave near the Bahamas on August 25, 1954, and gradually strengthened as it moved northwestward. On August 27, Carol intensified to reach winds of , but weakened...

During the first three years of the Project, scientists used three specially
instrumented Air Force Hurricane Hunters

The Hurricane Hunters are aircraft that fly into tropical cyclones in the North Atlantic Ocean and Northeastern Pacific Ocean for the specific purpose of directly measuring weather data in and around those storms. In the United States, the Air Force, Navy, and NOAA units have all participated in...

structure and energy budget of hurricanes for the first time.

In 1959, the Project was moved to Miami and collocated with the Miami hurricane forecast
office. Simpson left the Project to complete his doctoral degree and Robert Cecil Gentry
was appointed NHRP director. The Department of Commerce leased two DC-6 aircraft and
received a B-57 jet from the Air Force so that NHRP could continue to carry out airborne
experiments on hurricanes. The combination of research project, forecast center, and
aircraft facility was dubbed the "National Hurricane Center

" (NHC). This has caused
later confusion, since 1967 the NHC name has been used exclusively by the forecast center.
However the Project and Research Flight Facility (RFF) remained separate entities, with
their own personnel, budgets, and objectives.

statistical track program (NHC-64), wrote a manual on hurricane forecasting, and evaluate
the accuracy of track forecasts. Starting with Hurricane Esther (1961)
