Officials up and down the Northeast coast warned that Hermine could hit the region with strong winds and possible storm surge, as forecasters predicted that it could strengthen back into a hurricane later on Sunday.
Still, storm trackers said Hermine’s path was unclear. By Sunday morning, it had moved away from the coast, centered about 295 miles southeast of Ocean City, Maryland. Hermine’s top sustained winds remained at 65 mph as it moved east-northeast at 12 mph.
The National Weather Service said a tropical storm warning remained in effect for Rehoboth Beach in Delaware, which could experience wind gusts of up to 50 mph and “life-threatening” storm surges during high tide late Sunday and into Monday.
Virginia Beach also remained under a tropical storm warning Sunday, with the weather service describing conditions as “breezy to windy.” No significant rainfall was expected for the area, although scattered rain may occur in parts of southern New England and in the mid-Atlantic states.
In New Jersey, tropical storm-force winds could whip up on Monday, and record flooding remained a threat south of the Atlantic City area.
The National Hurricane Center maintained its tropical storm watch for Martha’s Vineyard and Nantucket and said dangerous storm surges would continue along the coast from Virginia to New Jersey.
“The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline,” the Hurricane Center said in a morning advisory.
Hermine already caused two deaths, damaged properties and left hundreds of thousands without electricity from Florida to Virginia. It spawned a tornado in North Carolina and closed beaches as far north as New York.
“This is not a beach weekend for anyone in the Mid-Atlantic to the northeast,” said Eric Blake, a hurricane specialist at the National Hurricane Center in Miami.
Hermine rose up over the Gulf of Mexico and hit Florida on Friday as a Category 1 hurricane before weakening to a tropical storm across Georgia.
Forecasters expected Hermine to regain hurricane force on Sunday as it travels up the coast before weakening again to a tropical storm by Tuesday.
And since sea levels have risen up to a foot due to global warming, the storm surges pushed by Hermine could be even more damaging, climate scientists say.
Michael Mann at Pennsylvania State University noted that this century’s one-foot sea-level rise in New York City meant 25 more square miles flooded during Superstorm Sandy, causing billions more in damage.
“We are already experiencing more and more flooding due to climate change in every storm,” said Michael Oppenheimer, a geosciences professor at Princeton University. “And it’s only the beginning.”
