Remains of Nicole Drench Southeast and Mid-Atlantic

A day after Hurricane Nicole battered Florida, the storm merged with another weather system on Friday as it moved north as a tropical depression and then as a posttropical cyclone, flooding parts of the Southeast and mid-Atlantic states with several inches of rain, they said forecaster said.

An excessive rain forecast for Friday by the National Weather Service Weather Prediction Center showed much of the country from Georgia’s northern border to Maine was at low risk of flash flooding. A smaller area further inland — from western North Carolina to eastern Ohio and western Pennsylvania and further north into upstate New York — faced a mild risk of flash flooding.

There is a possibility that creeks could flood the southern and central Appalachian Mountains, particularly in the Blue Ridge Mountains, the weather service said. Flood warnings were in effect from northeast Georgia and northwest South Carolina to western North Carolina and southwest Virginia through Friday evening.

In New York City, weather and government officials warned of strong winds and the possibility of more than 2 inches of rain from Friday night through Saturday morning, which could cause severe flooding in low-lying areas.

Electric utilities in and around New York braced for a possible blackout, and the city activated its flash flood contingency plan, which included checking and cleaning street drains. Officials in charge of the city’s subway system, as well as S-Bahn lines, directed emergency teams to clean out drains, pump out low-lying sections and remove debris from tracks as needed.

Gov. Kathy Hochul said New York State authorities stand ready to help local communities if needed. She advised caution when traveling. “As of Friday night, a late-season weather system has the potential to dump three inches or more of rain in some locations, and I urge all New Yorkers to prepare in the event of a flooding situation,” she said in a statement.

Nicole grabbed 30 mph winds with higher gusts as she moved northeast through the Carolinas on Friday. Tornadoes were possible Friday night in southeastern Virginia and the Delmarva Peninsula, which spans Delaware, Maryland and Virginia, according to the National Hurricane Center.

The central Appalachian Mountains, north mid-Atlantic and New England could get one to three inches of rain through Saturday morning, forecasters said.

Earlier Friday, Georgia was threatened by flash floods and tornadoes. Governor Brian Kemp urged residents to remain vigilant, but did not declare a state of emergency. The Georgia Emergency Management and Homeland Security Agency urged residents to take precautionary measures at high tide. Similar warnings were issued in the Carolinas.

While Florida received the brunt of Nicole’s impact, areas further north braced for heavy rain. Up to four inches were expected for parts of the Southeast and Appalachian Mountains, as well as parts of Tennessee, Kentucky and Ohio by Saturday. Areas along the Blue Ridge could get up to eight inches.

The storm was expected to weaken into a post-tropical cyclone later on Friday, then dissipate as it merges with another weather system intruding from the west. Nicole’s impact will be felt across the eastern United States by Saturday morning, forecasters said.

Nicole made landfall in Florida Thursday as a rare November hurricane, causing severe flooding and devastating coastal erosion on the state’s Atlantic coast.

The storm swept across the state, killing at least four and shutting down hundreds of thousands of customers.

In Volusia County, at least two dozen hotels and condos have been deemed unsafe, prompting the evacuation of about 500 mostly elderly residents.
