Gov. Andrew Cuomo revealed new yellow zones in areas of Westchester County due to rising cases of COVID-19.

They include parts of Peekskill, a portion of the village and town of Ossining, the more populated sections of Tarrytown and Sleepy Hollow, the heart of New Rochelle, and Yonkers.

Schools are allowed to remain open. However, 20% of in-person students, faculty and staff over the next two weeks will have to be tested for the virus.

If the positivity rate is lower than the yellow zone's current seven-day positivity rate, testing at that school will no longer be required. If it's not, 20% of in-person students, faculty and staff will have to be tested biweekly.

Restaurants and bars can remain open. They may offer indoor and outdoor dining, but no more than four people can sit at each table.

Houses of worship are limited to 50% capacity.

Westchester County Executive George Latimer said during his briefing Thursday that people have to listen to health guidelines, continue wearing masks and to socially distance to get COVID-19 under control. He also told his constituents to think closely about the choices they make over the Thanksgiving holiday. He said the risk of spreading the virus should outweigh the joy of seeing family this year.

According to Latimer, there are currently 3,975 cases of COVID-19 in Westchester County, up 400 cases over several days. There are 135 people hospitalized with the virus, the most since the spring.

“Additional steps have to be taken. How severe those regulatory steps are is yet to be determined and the governor has laid out a slow and steady process for less severe to the more severe,” said Latimer. “We hope that we can work together to avoid going to the next level up."
