Long Island is digging out after a historic snowstorm dumped more than two feet of snow across parts of the region, including an unofficial 29.1 inches recorded in Islip.

While major roads are gradually reopening, officials warn that dangerous conditions will linger for days.

Travel bans issued by Governor Kathy Hochul, Suffolk County Executive Edward Romaine, and Nassau County Executive Bruce Blakeman were largely respected. Nassau police rescued about 75 stranded motorists but reported no violations.

Suffolk police recorded only four active crashes late Monday morning, while New York State Police assisted nearly 50 motorists and handled more than two dozen accidents.

Even as highways clear, black ice remains a serious threat.

Warmer air temperatures later this week will melt snow, but frozen ground will cause water to refreeze overnight.

Robert Sinclair of AAA Northeast cautioned that posted speed limits apply only under ideal conditions.

Drivers are urged to reduce speed, leave extra space, and stay alert.

Old Westbury Police Chief Stuart Cameron also announced increased patrols due to concerns about reckless driving on icy roads.

• Clear the tailpipe: Blocked exhaust pipes can cause carbon monoxide poisoning.

• Clear the entire vehicle: Remove snow and ice from the roof, hood, and windows. It’s required by New York law and prevents hazards for other drivers.

• Warm up safely: Start your car only after ensuring the tailpipe is clear.

• Check your wheels: Ice buildup can affect alignment and handling.

• Drive carefully near trucks: Snow can fall from large vehicles.

• Keep distance: Leave plenty of room in front, behind, and beside your vehicle.

The storm left behind heavy, wet snow — sometimes called “heart attack snow” — which poses serious health risks.

Dr. Alan Job of Northwell Health warns that overexertion can cause back and wrist sprains, herniated discs, and even cardiac emergencies.

Doctors Recommend:

• Take breaks and work in short shifts.

• Hydrate and warm up if fatigued.

• Lift with your legs, not your back.

• Shovel smaller loads.

• Stretch your back, hamstrings, and quadriceps before and after.

Anyone experiencing chest pain, dizziness, or shortness of breath should stop immediately and call 911.

Suffolk Fire Rescue advises:

• Keep safety guards in place.

• Never reach into a jammed machine while running.

• Refuel and operate snowblowers outdoors only.

While Long Island begins to recover, officials stress that caution — both on the roads and in driveways — remains essential in the days ahead.
