KBA99 is a NOAA Weather Radio station that is programmed from the National Weather Service forecast office in Honolulu, Hawaii with its transmitter located on Mt. Ka'ala in Oahu. Although this station primarily serves Honolulu and surrounding islands, several repeater translators are added, broadcasting weather and hazard information for the entire state of Hawaii and can be heard 40 miles into the Pacific Ocean. It also transmits on Oceanic Time Warner Cable digital channel 880 for all of Hawaii.
It is the only NOAA station in the United States that still uses the early version of the "Tom" voice.
Hourly conditions on this station are reported for the following cities - On Oahu: Honolulu International Airport, Kalaeloa, Kaneohe, and Wheeler Field. On Kauai: Lihue, and Barking Sands. On Molokai: Molokai Airport. On Lanai: Lanai City. On Maui: Kahului, Kapalua, and Haleakalā. On The Big Island: Hilo, Kona, and Bradshaw Field.
As of June 25, 2014, translator WWF39 in Hawaii Kai has moved from frequency 162.400 MHz to 162.450 MHz as new upgraded equipment was installed at the station, producing an enhanced signal. This enhancement allows important emergency messages as well as weather forecasts and current conditions to be heard in portions of East Oahu where the broadcast was previously not available.
- All transmitters broadcast with a power output of 1,000 Watts unless otherwise noted.
