KHB34

KHB34 is a NOAA Weather Radio (NWR) station that serves a part of the South Florida metropolitan area on an assigned frequency of 162.550 MHz; it can also be heard about 60 miles (100 km) east into the Atlantic Ocean, nearly to the Bahamas. Programming originates from NOAA's National Weather Service (NWS) weather forecast office (WFO) in Miami, Florida, with the transmitter located in Andover/Miami Gardens. It continuously broadcasts weather and marine forecasts, as well as civil hazards information, for the following counties in the South Florida region: Miami-Dade and Broward. The radio station plays a vital role in alerting the general public to hazardous weather conditions in an area prone to severe weather events such as lightning storms, tornadoes, waterspouts and hurricanes. The signal also reaches North Key Largo and inland parts of mainland Monroe, eastern Collier, far southeastern Hendry, and most of Palm Beach counties – however it does not issue alerts for those areas.

There are other adjacent NWR stations that serve the forecast area. WNG663 (162.425 MHz) also covers Miami-Dade from Princeton, near Homestead, as well as mainland Monroe and the Upper Keys. Other stations programmed by the Miami-South Florida WFO include: KEC50 Mangonia Park/West Palm Beach (162.475 MHz) to the north, serving Palm Beach County and the adjacent coastal waters; WXM58 Belle Glade (162.400 MHz) to the northwest, in western Palm Beach County near Lake Okeechobee; and WWG92 Naples (162.525 MHz) to the northwest, near Florida's west coast, serving Collier, Hendry and a portion of mainland Monroe County.

Recognizing the need to serve the local area's large Spanish-speaking population, NWS added a low-power station in June 2012, WZ2531 (162.500 MHz) transmitting from Hialeah - the first dedicated Spanish language NWR station in Florida. Its broadcast, featuring a computer-synthesized voice known by the nickname "Javier", covers Miami-Dade and Broward counties.
