The states on the list can change on a daily basis.
California, Georgia, Iowa, Indiana, Louisiana, Mississippi, Nevada and Tennessee were the new states added.
Last week, Gov. Cuomo, along with New Jersey Gov. Phil Murphy (D) and Connecticut Gov. Ned Lamont (D), announced a joint incoming travel advisory requiring a 14-day self-quarantine for travelers arriving from states with "a positive test rate higher than 10 per 100,000 residents over a 7-day rolling average".
The initial eight states remaining on the list are Alabama, Arizona, Arkansas, Florida, North Carolina, South Carolina, Utah, and Texas. In recent testing results, 524 people NY state residents were reported to have COVID-19 - that's down from over 18,000 positive results at the pandemic's peak in April in the Empire State.
Any travelers from states that meet either of the two thresholds on coronavirus infection rates are being told they have to self-quarantine for 14 days upon arriving in Connecticut, New York, or New Jersey.
"As an increasing number of states around the country fight significant community spread, NY is taking action to maintain the precarious safety of its phased, data-driven reopening", Cuomo said in a statement.
This morning's announcement means 16 states are now under the travel advisory. The seven-day rolling average for the percentage of positive tests in New York City, which was once the nation's epicenter of the virus, was was 1.1% as of Monday.
"If you are violating the quarantine, you can be subject to a judicial order and mandatory quarantine", Cuomo said last week.
New Jersey has a similar quarantine, but unlike NY, it's not enforceable or mandatory.
