The National Weather Service Miami, Florida is a local weather forecast office of the National Weather Service (NWS) that serves six counties in South Florida – Broward, Collier, Glades, Hendry, Miami-Dade, and Palm Beach – as well as the mainland portion of Monroe County. This office was originally established in 1879 as a Signal Corps station near the Jupiter Inlet Light, before becoming a Weather Bureau Office (WBO) in 1891. The WBO at Jupiter was moved southward to Miami in 1911, due to the city's rapidly growing population. In 1930, a separate Weather Bureau Airport Station (WBAS) was established at the Miami Municipal Airport. The WBAS was later moved to the Miami International Airport in 1942 and remained there until ceasing operations in 1975.
Under the leadership of Grady Norton, the joint hurricane warning service, which was a predecessor to the National Hurricane Center, was moved from the WBO Jacksonville to the WBO Miami in 1943. The Weather Bureau was renamed the National Weather Service in October 1970. Thus, WBO Miami became NWS Miami. As part of an organizational restructuring plan in the 1990s, an NWS office in West Palm Beach was merged with NWS Miami. Since 1995, this office of the NWS has been located on the campus of Florida International University and adjacent to the National Hurricane Center.
