A tornado watch in New Jersey means that conditions are favorable for the development of tornadoes in and near the watch area. It doesn’t mean that a tornado has been sighted or is imminent, but rather that atmospheric conditions are present that could lead to tornado formation.
The National Weather Service (NWS) issues a tornado watch when atmospheric instability, moisture, and wind shear combine to create an environment conducive to severe thunderstorms capable of producing tornadoes. Wind shear refers to changes in wind speed and direction with height, which can cause rotation in thunderstorms, potentially leading to tornado development.
When a tornado watch is issued for New Jersey, it’s crucial to stay informed and be prepared. Here’s what you should do:
- Stay Informed: Monitor weather updates from the NWS, local news channels, and reliable weather apps. Pay close attention to any warnings that are issued.
- Have a Plan: Discuss a tornado safety plan with your family or household. Designate a safe room or shelter, ideally an interior room on the lowest level of your home, away from windows.
- Assemble a Disaster Kit: Ensure you have a well-stocked disaster kit that includes essential supplies such as water, non-perishable food, a flashlight, a battery-powered or hand-crank radio, a first-aid kit, and any necessary medications.
- Secure Outdoor Objects: Bring loose outdoor objects inside, such as lawn furniture, trash cans, and decorations. These items can become dangerous projectiles in strong winds.
- Be Aware of Warning Signs: Be vigilant and watch for signs of approaching severe weather, such as dark, greenish skies, large hail, a loud roar like a freight train, or a rotating cloud base.
If a tornado warning is issued for your area, which means a tornado has been sighted or indicated by radar, immediate action is required. Seek shelter immediately in your designated safe room or basement. If you are in a vehicle, abandon it and seek shelter in a sturdy building or a low-lying area, covering your head and neck. Avoid seeking shelter under bridges or overpasses, as these can actually amplify wind speeds.
New Jersey, while not typically associated with the large-scale tornado outbreaks seen in the Midwest, is still susceptible to tornadoes. They are often weaker and shorter-lived, but can still cause significant damage. The risk is higher during the spring and summer months, but tornadoes can occur at any time of year.
Understanding the difference between a tornado watch and a tornado warning is essential for safety. A watch means conditions are favorable, while a warning means a tornado is imminent or occurring. By staying informed and taking appropriate precautions, residents of New Jersey can minimize their risk during severe weather events.
