From this article.
Where I live in western NY south of Buffalo, NY. I am able to listen to WCBS AM 880, New York, KYW AM 1060 Philadelphia, and WBAL AM 1090, out of Baltimore, to name just a few AM Radio stations available when the nighttime skywave sets up. I was listening to WCBS radio on the night the storm was hitting New York, when high tide was coming WCBS radio was on generators, but still putting out a booming signal, they however had begun to simulcast on a local New York FM station, because they were afraid they would have to shut down the AM broadcast, but I am unaware if they ever did. For those not familiar with the east coast, many of the Philadelphia, TV stations, are local TV coverage, for much of New Jersey, including many of the places devastated by hurricane Sandy. No doubt the broadcast media has done much to help save lives in this terrible storm.
As we move into Day 2 of Hurricane Sandy (now reclassified as Superstorm Sandy), TV news crews from Washington to Boston are working at full force providing wall-to-wall coverage, armed with precautions including ropes to tether satellite masts, cash in case of getting stranded and out-of-market reinforcements.
