Photo: Peconic Avenue in Riverhead Flooded

Residents who are still on the roads -- town officials have declared a state of emergency, meaning drivers are advised to stay off the roadways -- will find that traversing Peconic Avenue in Riverhead has become impossible. The road, which leads to the Riverside traffic circle, is entirely flooded.
