NOAA Weather Radio station WNG591 operates on 162.500 mHz and transmits out of Coudersport, Pennsylvania. The station serves Cameron, McKean, and Potter counties in Pennsylvania, and Allegany and Cattaraugus counties in New York. Alerts broadcast on this station are transmitted by NWS State College (CTP) for Cameron, McKean, and Potter counties in Pennsylvania. NWS Buffalo (BUF) covers the two New York counties.

Although WNG591 does not appear to serve Cameron, PA, or Allegany and Cattaraugus, NY, I can confirm they do. I have gotten isolated alerts for Cameron County in PA before relayed over WNG591. I have also gotten Buffalo alerts for Allegany and Cattaraugus NY relayed over WNG591.
