NEW YORK (CBSNewYork) – As more severe weather heads our way, New York City officials are issuing guidance for New Yorkers.

The move comes after National Weather Service officials confirmed an EF-1 tornado hit Stanhope and Hopatcong, N.J.

“The increased potential for severe thunderstorms may create dangerous travel conditions this evening,” NYC Emergency Management Commissioner Joseph Esposito said. “New Yorkers should stay inside during periods of severe weather. If you are outside during a thunderstorm, avoid open areas and immediately seek shelter indoors.”

The Office of Emergency Management issued the following guidance:

If you are caught outside:

  • Stay away from tall, isolated trees and other tall objects.
  • Avoid open areas like fields or parking lots.
  • Stay away from water and wet items.
  • An automobile can protect you from a lightning strike because the current will flow through the car’s metal frame. If you are in a car, do not touch any exposed metal connected to the car.
  • If someone is struck by lightning, call 9-1-1.
  • Do not walk or drive through flooded streets; the actual depth of the water may not be apparent. Turn around, don’t drown!
  • Floodwater can be contaminated. Avoid contact with sewer water, as it poses a serious health risk.
  • Have heightened awareness of cars, particularly when approaching or crossing intersections.
  • Never touch or go near downed power lines, even if you think they are safe.
  • Report any downed power lines and avoid standing in floodwater, as it can carry electrical current.

If you are indoors:

  • Wait 30 minutes after the last clap of thunder before venturing back outside.
  • Charge cell phone batteries, gather supplies, and turn refrigerators and freezers to a colder setting.
  • If you are affected by an outage, turn off all appliances and keep refrigerator and freezer doors closed to prevent food spoilage.
  • Do not use generators indoors. If you lose power and have a disability or access needs, or use Life Sustaining Equipment (LSE) and need immediate assistance, please dial 9-1-1.

What to Do if a Tornado Strikes

  • Go to your basement or the lowest point of your residence. If an underground shelter is not available, move to a small interior room or hallway on the lowest floor and get under a sturdy piece of furniture. Put as many walls as possible between you and the outside.
  • Stay away from windows.
  • Avoid places with wide-span roofs, such as auditoriums, cafeterias, large hallways, or shopping malls.
  • If you are outside, seek shelter inside a sturdy building immediately if a tornado is approaching.
  • Being in a vehicle during a tornado is not safe. The best course of action is to drive to the closest shelter or building. If you are unable to make it to a safe building, do not try to outrun a tornado in your vehicle. Either get down in your vehicle and cover your head with your hands, or abandon your vehicle and seek shelter in a low-lying area such as a ditch. Do NOT take cover under an overpass or bridge.
  • Be aware of flying debris.
  • Stay tuned to your local radio and television stations for the latest storm information.
