Southampton Town Supervisor Anna Throne-Holst, speaking on WLNG radio Monday morning, said that officials were concerned that some residents in mandatory evacuation zones had not left.
"We are afraid that some people aren't paying heed to calls to evacuate from low-lying areas," she said.
Southampton Town ordered the evacuation of Dune Road and low-lying areas early Sunday. The town provides a tool on its Web site listing the surge potential for every address in the township. Residents of zone 1 are included in the evacuation order. Ms. Throne-Holst told WLNG that the town may asks residents of zones 2 and 3 to leave today.
Ms. Throne-Holst said she expected the worst of Hurricane Sandy to begin at about sundown tonight and continue to 6 a.m. Tuesday.
"We are seeing some flooding, but we haven't seen the brunt of it yet," she said. "It may be deceptive at this point, but it is going to get really, really bad by 6 tonight."
Comparing Hurricane Sandy to 2011's Tropical Storm Irene, she said, "It's a very different storm . . . I can't emphasize this enough."
"The trajectory is one that we haven't seen in our lifetimes."
Ms. Throne-Holst said that "major" power outages are expected. "This is such a wide storm, it will be a very, very hard job for our utility crews to get power restored."
"The sheer reality of the number of outages . . . people simply need to prepare for that at this point," she said.
The Red Cross has opened a shelter at the Hampton Bays High School at 88 East Argonne Road.
