Sussex County emergency officials continue to monitor the development of a late-winter storm that threatens coastal and low-lying areas with significant flooding, and are encouraging residents in those communities to move now before the water rises.
The National Weather Service has issued a coastal flood warning and a high wind warning for Sussex County through Thursday, March 7. A storm system moving through the Midwest is expected to intensify into a nor’easter off the Virginia coast Wednesday, swelling tides at least 4 feet above normal and sending heavy rains and high winds ashore. The storm could even wrap up with a coating of snow, possibly 1 to 3 inches, before slowly moving out to sea early Thursday morning.
While no evacuations have been ordered, residents in communities along the Delaware Bay, including Primehook Beach and Broadkill Beach, as well as around the Inland Bays, particularly Angola and Oak Orchard, should be mindful of the forecasts and prepare to move to higher ground while roads are clear. Strong easterly and northeasterly winds over the next 36 hours will push water ashore and into flood-prone areas.
“This nor’easter has the potential to rival some tropical storms and hurricanes we’ve seen in the past when it comes to flooding; it’s expected to be that strong,” Sussex County Emergency Operations Center Director Joseph L. Thomas said. “Areas that have historically flooded stand a very good, almost certain, chance of flooding in this event, which could last through several tide cycles. So that is why we are encouraging residents in these areas to think about going somewhere else.”
Forecasters with the National Weather Service predict wind-swollen tides could last through the morning of Friday, March 8.
Meantime, strong, prolonged winds off the Atlantic Ocean and Delaware Bay - with gusts as high as 55 mph - could pile water onshore and in back bays, scouring beaches and flooding coastal communities. High winds, coupled with already-saturated ground, could bring down trees and knock out power lines throughout the county, Thomas said.
Emergency officials urge the public to be prepared and to monitor local forecasts for any changes or updates. Residents in low-lying areas should act now by moving vehicles, clearing storm drains and checking submersible pumps, Sussex officials said.
