Legendary Long Island Storm Archives

Historical Benchmarks
Category 3 Hurricane September 21, 1938

The 1938 'Long Island Express' Hurricane

186 mph peak gust • 47 mph forward speed • 15+ ft surge

The most powerful tropical cyclone in modern Long Island history. Barreled northward at 47 mph without warning, making landfall near Westhampton Beach. The storm severed Fire Island into multiple pieces, carving modern Shinnecock and Moriches Inlets, and leveling coastal estates across the South Fork.

Legacy: Modern coastal engineering benchmark. Established the importance of barrier dune preservation and permanent inlet jetties.
Post-Tropical Cyclone / Hybrid October 29, 2012

Superstorm Sandy

14 ft record surge • 90 mph gusts • 90% LI power loss

An unprecedented hybrid monster storm that made an abrupt westward turn into southern New Jersey, driving a record-shattering ocean surge straight into Long Island's South Shore. Submerged entire neighborhoods in Long Beach, Freeport, Lindenhurst, and Mastic Beach, creating the Old Inlet breach on Fire Island.

Legacy: Redefined FEMA Base Flood Elevations across Suffolk and Nassau, triggering major house raising and bulkheading projects.
Historic Mesoscale Blizzard February 8 - 9, 2013

Blizzard Nemo

33.5" in Medford • 30.0" in Port Jefferson • 60+ mph gusts

An extraordinary mid-latitude bomb cyclone that merged two distinct jet stream energy packets directly over Long Island. A stalled mesoscale snowband dropped 4 to 5 inches per hour for 8 consecutive hours across central and northern Suffolk, shutting down the Long Island Expressway and stranding hundreds of motorists.

Legacy: Led to permanent NYS Department of Transportation snowgate plows and GPS tracking for county snowplow fleets.
Category 2 Hurricane September 27, 1985

Hurricane Gloria

100+ mph peak gusts • Landfall over Central Islip

Made direct landfall on Fire Island and roared through central Suffolk County. Severe tree-fall and root-plate failure devastated the Long Island Lighting Company (LILCO) electrical grid, leaving 683,000 customers without electricity for up to 12 days.

Legacy: Sparked extensive utility tree-trimming mandates that evolved into PSEG Long Island's modern storm hardening programs.
Severe Drought Wildfire August 21 - 24, 1995

The 1995 Long Island Pine Barrens Wildfires

7,000+ acres burned • Sunrise Hwy closed • National Guard activated

Following a severe summer drought with Keetch-Byram Drought Index (KBDI) exceeding 600, multiple brush fires ignited in the pitch pine forests of Westhampton and Rocky Point. Driven by 30 mph coastal winds, flames leaped over four-lane Sunrise Highway and threatened Gabreski Airport.

Legacy: Created the Central Pine Barrens Joint Planning and Policy Commission and regional prescribed burn protocols.
Long Island Sound & Atlantic Sea-Surface Warming

Long Island Sound and the New York Bight have warmed at nearly triple the global ocean average rate over the past 50 years (+0.45°F per decade). This extra marine thermal energy delays autumn frost, extends coastal growing seasons, and fuels higher precipitation rates in winter nor'easters and summer cloudbursts.
