Atlantic Beach Tornado Strikes Long Island
On Thursday, August 20, 2026, a waterspout moved ashore at Atlantic Beach, Nassau County, and produced an EF-1 tornado that touched down on the South Shore of Long Island. The vortex traveled roughly a third of a mile on land, with a path width of about 100 yards, and generated wind gusts between 86 mph and 110 mph, according to the National Weather Service (NWS). The tornado ripped apart the Sun & Surf Beach Club and damaged the nearby Silver Point Beach Club, destroying or heavily damaging between 30 and 50 beach cabanas and shattering vehicle windows. No serious injuries were reported; one club employee sustained a minor head injury and declined medical care.
Dover, Delaware Tornado Impacts Capital
Later that evening, a second tornado touched down in Dover, Delaware. The NWS classified it as at least EF-1 with estimated peak winds of 105 mph. The funnel struck the downtown area, ripping roofs off the Days Inn and the Super Lodge along North DuPont Highway, toppling power poles, and damaging a Kraft-Heinz facility. Police reported downed trees, flooded roadways and power outages, but confirmed that no injuries occurred.
Background & Context
Tornadoes are uncommon in the Northeastern United States, especially on Long Island, where only nine have been recorded in Nassau County since 1950. Meteorologists noted that a strong low-pressure system, moist maritime air, and vertical wind shear created the conditions for the waterspouts that became tornadoes.
Data & Statistics
- Long Island: EF-1; wind speeds 86-110 mph; path ? 0.36 mi long, 100 yd wide; 30-50 cabanas damaged; ~200 people present at the club.
- Delaware: EF-1; peak winds 105 mph; roof loss at two hotels; power outages affecting > 40,000 residents; no injuries.
- Rainfall: 2-5 in across Nassau County and up to 5 in in Suffolk County, contributing to flash-flooding on the Long Island Expressway and parts of New Jersey.
Official Statements & Responses
Nassau County Executive Bruce Blakeman declared a state of emergency, activated the Emergency Operations Center, and ordered first-responders to search cabanas “cabana by cabana” for trapped occupants. Dover Mayor Robin Christiansen issued a state of emergency, urged residents to stay home, and lifted the declaration on Friday, August 21, 2026, to allow cleanup to proceed. The NWS confirmed both tornadoes after reviewing radar data, video, and damage surveys, and announced ongoing investigations into possible additional tornadic circulations. Local police warned motorists to expect debris, blocked lanes and delayed travel.
On-the-Ground Reports
Residents described a “whistling” or “train-like” sound preceding the tornado, followed by a sudden, violent wind that lifted cabanas, furniture and vehicle windows. Lifeguard Daniel Moran said the destruction eclipsed that of Hurricane Sandy on Long Island. In Dover, a woman described being trapped in a hotel room as the roof was ripped away, while a driver recounted debris striking his car and forcing a stop on North DuPont Highway.
Conflicting Reports & Gaps
Initial coverage varied on whether the Long Island event was a confirmed tornado. Some outlets reported a “possible tornado” pending NWS verification, while others cited an immediate confirmation. The exact number of cabanas destroyed also differed, with figures ranging from 30 to 50. The NWS has yet to release a final EF rating for the Delaware tornado, leaving the precise intensity open.
