This morning’s rain and the threat of thunderstorms later today has forced the cancelation of Riverhead’s annual Memorial Day Parade, officials with the American Legion said.
The rain, which began to fall early Monday, is expected to continue into the evening hours, according to the National Weather Service in Upton, which issued a hazardous weather advisory. Flash flooding is possible, the NWS reported.
Parades have also been canceled in Southold Town.
A ceremony at Calverton National Cemetery is planned for 1 p.m.
