Hurricane Erin Threatens Dangerous Coastal Conditions Along US East Coast, Sparks Warnings and Evacuations in North Carolina’s Outer Banks

Hurricane Erin, a high-end Category 2 storm with winds nearly reaching Category 3 status, is causing life-threatening rip currents and dangerous surf along much of the US East Coast. The hurricane is expected to bring destructive waves and storm surge to North Carolina’s Outer Banks, although it is not forecast to make landfall.

The impact of Erin is already being felt on US coastlines, with at least 75 rip-current rescues conducted along North Carolina’s southern coast on Monday. Wrightsville Beach has issued a no-swim advisory through Friday due to these hazardous conditions.

A tropical storm watch is currently in effect for the middle of North Carolina’s coast, extending north past Kitty Hawk, including the Pamlico Sound. This means that tropical-storm-force winds (39 to 73 mph) are possible within the next 48 hours in this area.

Dare and Hyde counties, which encompass most of the Outer Banks, have issued local states of emergency with mandatory evacuations for Hatteras and Ocracoke islands. To the south, tropical storm warnings remain in effect for the Turks and Caicos Islands and the southeast Bahamas. A tropical storm watch is also in place for the central Bahamas.

Erin’s outer bands have caused flooding, power outages, and airport closures on affected islands in recent days. Puerto Rico has also experienced flooding and widespread power outages due to Erin’s outer bands.

The hurricane exploded in strength over the weekend to become a Category 5 storm, fueled by very warm water. Although its category has since changed, its threat remains significant. Erin is expected to fluctuate between a high-end Category 2 hurricane and a Category 3 hurricane through at least midweek.

The impact of Erin will be felt primarily through water: large, pounding surf, dangerous currents, and coastal flooding during high tides. Extensive beach erosion is likely in the Outer Banks, with waves of 20 feet or more forecast this week, according to the National Weather Service. This could lead to severe flooding inland due to the destruction of protective dune structures.

Multiple homes in the Outer Banks have collapsed into the ocean in recent years, including at least three around this time last year from Hurricane Ernesto’s waves. At least two homes in Rodanthe are considered “very, very vulnerable” to collapse this week.

In addition, the tides around the Outer Banks will reach their highest levels of the month on Wednesday and Thursday. Adding Erin’s large waves to the mix could cause serious coastal flooding.

Bermuda also lies in Erin’s path of influence, with forecasters expecting the island to see very rough seas and possibly tropical storm–force winds later this week.

The most active stretch of the Atlantic hurricane season typically occurs in mid-August, and this year is no exception. The National Hurricane Center is monitoring two areas for possible tropical development in the same part of the Atlantic where Erin tracked last week.

The first area of disorganized showers and thunderstorms is over the open tropical Atlantic and has a medium chance of developing into a tropical depression or tropical storm within the next week.

Another area near Africa’s Cabo Verde islands has a low chance to develop over the next few days before it encounters more hostile atmospheric conditions at the end of the week.

The next two tropical storms that develop in the Atlantic will be named Fernand and Gabrielle.
