A meteorologist for a television station in Rochester was fired Sunday after he uttered a racial slur on air while describing a city park named after the Rev. Dr. Martin Luther King Jr.

Jeremy Kappell, a News10NBC meteorologist, used a derogatory term for black people as he was describing a picture of the park during a Friday broadcast about the weather, inserting the slur between “Luther” and “King.” A clip of the segment began circulating over the weekend, drawing furious reactions and calls for reprimand.

Reached by phone on Monday evening, Mr. Kappell confirmed that he was fired Sunday. He said that he had not intended to use the word during the unscripted broadcast but had misspoken. Mr. Kappell said he had been a meteorologist for the television station since October 2017 and had two years left on his contract.

He released a video Monday evening responding to his firing, saying that he had jumbled his words. He apologized to those who felt hurt.
