Upending plans at the last minute, Red Bank Regional High will not reopen for in-person classes Monday, according to an announcement made shortly before dawn.

An email sent to the school community at 5:29 a.m. read, in full, “RBR will be in full remote mode on Monday, Nov. 30th.”

No further information was immediately provided on the school website.

After four weeks of all-remote instruction, the school had planned to resume a hybrid schedule, in which about half of its students would be in classrooms Monday, Superintendent Lou Moore said in an announcement Wednesday.

COVID-19 cases have been rising in the three towns that comprise the school district. As of Sunday, Red Bank has had 673 since March, up from 407 on November 1; Little Silver, has had 138, up from 84; and Shrewsbury has seen 155, up from 97, according to the Monmouth County government.

The county also reported four new deaths from the virus Sunday, for a total 808 since the start of the pandemic. Another 92 fatalities are classified as “probable” results of the illness.
