Storm Spotting: A Guide for Homeowners

What is Storm Spotting?

An estimated total of 16 million thunderstorms occur each year. While most storms are harmless, there are certain severe storm types that are known to inflict damage to buildings and can endanger the lives of individuals. With the help of storm spotting, the details of potential weather hazards can be reported to the public ahead of time in order to limit the number of damages, injuries, and fatalities in the event of severe weather.

Storm Spotting: A Guide for Homeowners

Defined as the observation of severe weather and the monitoring of storm development and progression, the act of storm spotting plays an important role in public safety. By identifying the physical structure of severe storms and learning how to identify different types of storms, storm spotting has led to better warning systems and informational statements put out by the National Weather Service and local news stations.

While weather watching has been a popular activity for over a century, trained storm spotters today analyze temperatures, barometric pressure, wind speed, and doppler radar to make weather observations. Playing a vital role in everyday life, storm spotting benefits the general public and local public safety officials.

What is a Storm Spotter and Who Can Be One?

Storm spotters are generally trained individuals who want to learn more about the weather while providing a service to the local community. Since storm spotters are volunteers and not meteorologists, becoming one is relatively easy and is open to anyone who is interested. After attending a free Skywarn training class provided by the National Weather Service, storm spotters will learn about different thunderstorm types and how to file a first-hand report when encountering severe weather.

Storm Spotter Vs. Storm Chaser

Defined as the deliberate pursuit of severe weather, storm chasing is dangerous and is best left to the professionals. Compared to storm spotting, chasers will often travel thousands of miles a year to get up close and personal to severe weather, while storm spotters typically remain close to home. Allowing researchers to observe storms up close to gather data, storm chasers are generally made up of scientists who study weather and want to learn more about severe weather phenomena.

Considerations for Homeowners 

Even if weather patterns may not be the number one deciding factor when moving to a new area, staying up to date with the local weather of a region will lead to better home-buying decisions. Knowing about what severe weather events and weather risks are frequent in the area that are you looking to buy will ensure your safety as a new homeowner. 

If you are looking at homes for sale in Raleigh for example, it is important to educate yourself about the severe weather conditions that the city experiences. Known for its seasonal variation and high risk of thunderstorms, flooding, and potential hurricanes, make sure to prepare for any possible severe weather when buying a house in Raleigh.

Whether you are on the hunt for Raleigh townhomes for sale or single-family homes, it might be a good idea to figure out the cost of homeowners insurance and determine whether or not the area you are looking to buy is at a high risk of natural disasters before moving to Raleigh. If you are looking to sell your home in Raleigh, the same conditions should be thought through before moving to a new area.

How to Become a Storm Spotter 

Once you have decided that you want to become a storm spotter then it is time to attend a storm spotter training class that is offered in your area. This volunteer training program is called Skywarn and is taught by the National Weather Service. Offering both online storm spotting courses and local storm spotting courses, these training sessions feature interactive presentations from meteorologists.

Typically held in early spring during the months of March or April, these training classes normally last around two hours long and are free of charge. Recommended for ages 18 and older and open to the general public, training is held in the evenings during the week and on select Saturdays. Since the location for local training classes may vary, spotters may need to travel up to 15 miles to attend a nearby local session.

What Weather Events Do Spotters Look For? 

Trained storm spotters are taught how to identify severe weather and how to distinguish the different physical structures of severe storms. The most common weather events that storm spotters look for and report include: 

  • Tornadoes 

  • Flash Flooding 

  • Wall Clouds

  • Funnel Clouds

  • Lightning 

  • Winter Weather 

  • Wind 

  • Hail 

  • Marine Hazards 

  • Additional Environmental Hazards

Tornadoes 

Tornadoes develop from severe thunderstorms when warm air meets a cold front. Recognized as a violently rotating column of air that is capable of inflicting mass destruction on any area that it touches, tornadoes can last for more than twenty minutes and can have winds that reach speeds of 200 to 300 miles per hour. The common signs of tornadoes include a dark or green-colored sky, low-lying clouds, large hail, and a loud roaring noise that sounds like a freight train.

Safety Information

Since tornadoes can impact anywhere in the country at any time during the year, there are certain tips and safety precautions to take that will help keep you and your family safe if a tornado strikes.

  • Identify a safe place in the home to gather such as a basement, storm cellar, or interior room with no windows on the lowest floor. 

  • Protect your head and take shelter under something sturdy for additional protection.

  • Do not stay in a mobile home. 

  • Prepare an emergency kit ahead of time including water, non-perishable food, and medication. 

  • Watch out for weather conditions. 

When and What to Report

If you spot a tornado, immediately seek shelter and help alert others in the area by reporting it to the National Weather Service and local newsroom.

  • What damage did you observe? 

  • How long was it on the ground? 

  • When did it start and end? 

  • How wide was it? 

  • How far did it travel?

Additional Tornado Resources 

Flash Flooding 

A flash flood is a rapid flooding of an area caused by heavy rainfall in a short period of time, a hurricane, or a tropical storm. Flash floods are one of the most common natural disasters.

Safety Information 

Since flash floods can occur suddenly and within six hours of heavy rainfall, it is important to be prepared in order to stay safe.

  • Purchase flood insurance. 

  • Seek higher ground as quickly as possible. 

  • Unplug electronic equipment before flooding occurs. 

  • Tie down or bring in any outdoor equipment or furniture that can be damaged during flooding. 

  • Do not drive through flooded roads. 

  • Prepare an emergency kit ahead of time. 

  • Make a record of personal property. 

  • Follow all instructions from public safety officials.

When and What to Report

Since flash flooding can be life-threatening, it is important to report flooding as soon as possible.

  • What roadways, rivers, or streams are flooded? 

  • What is the approximate water depth? 

  • Is the water level continuing to rise, staying steady, or falling? 

  • Is the flooding occurring in a known flood-prone area? 

  • Is there any damage from the flooding or mudslides?

Additional Flash Flooding Resources

Wall Clouds 

A wall cloud is a large low cloud that is located in the area that has the strongest updraft during a thunderstorm. Rotating wall clouds are typically where strong tornadoes form. By identifying the presence of a wall cloud, storm spotters can predict the occurrence of a tornado.

Safety Information

Wall clouds can be as large as five miles in diameter and are normally an early warning sign of a strong thunderstorm or dangerous tornado.

  • Seek shelter as soon as a wall cloud is spotted. 

  • Watch carefully for any signs of rotation. 

  • File a report with the National Weather Service and local newsroom. 

  • If a tornado forms, follow all tornado safety tips.

When and What to Report

The identification of a wall cloud needs to be reported as soon as possible since it can be an early warning that a tornado will touch down within minutes or within the hour.

  • Is the wall cloud rotating? 

  • How long has it existed? 

Additional Wall Cloud Resources 

Funnel Clouds

Referred to as a condensation funnel, a funnel cloud is a funnel-shaped cloud that is made up of condensed water droplets and rotating air. Extending outwards towards the ground, funnel clouds are a rare cloud formation that does not touch the ground. 

Safety Information

Produced by severe thunderstorms, funnel clouds are considered to be the start of a tornado. However, funnel clouds are only dangerous as soon as they touch the ground.

  • If you spot a funnel cloud while driving, pull off the road and seek immediate shelter. 

  • If stuck inside of your vehicle, pull off to the side of the road, protect your body, cover your head, and crouch below the windows. 

  • Always be prepared when leaving your house by keeping a disaster supply kit in your trunk that includes water, first aid supplies, non-perishable food, medication, a blanket, and a flashlight. 

When and What to Report

As soon as a funnel cloud is reported, a tornado warning will be issued.

  • What does the funnel cloud look like?

  • Is the funnel cloud rotating? 

  • Is the funnel cloud touching the ground?

Additional Funnel Cloud Resources

Lightning 

Normally occurring in the clouds, lighting is an electrical discharge between storm clouds and the ground. This spark of electricity caused by imbalances can heat the surrounding air up to 50,000 degrees Fahrenheit which is five times hotter than the surface of the sun.

Lightning at night time lights up the sky and is the precursor to a storm

Safety Information 

Contrary to popular belief, lightning can and will strike the same spot multiple times. Normally occurring during thunderstorms, lightning strikes kill up to 2,000 people every year. 

  • Always seek shelter and stay indoors during a thunderstorm.

  • Avoid water.

  • Avoid electrical equipment.

  • Avoid windows, doors, porches, and concrete. 

  • Do not stay in open vehicles or open structures. 

When and What to Report

  • Volcanic ash accumulation and any damage. 

  • Any injuries or fatalities as a direct result of the weather.

How Do You Stay Safe As A Storm Spotter?

As a storm spotter, personal safety is the number one priority. Since storm spotting can be dangerous and life-threatening, all spotters can ensure their own safety and minimize the risk of injury and deadly situations by following the acronym ACES. Put in place by public safety officials, ACES is a guideline that all storm spotters should follow in order to stay safe.

ACES stands for: 

  • Awareness: Always observe your surroundings and pay attention to changing weather conditions. Place yourself out of harm’s way by monitoring all possible risks. 

  • Communication: Communicate with others around you and update them on your whereabouts.

  • Escape Routes: Always be aware of possible escape routes in case of a dangerous situation. 

  • Safe Zones: Know the closest shelter and safe area available to you if you can not access an escape route. 

Reporting Weather Events

The best way to report severe weather as a storm spotter is through the National Weather Service phone number, email, social media pages, or the Spotter Network. Make sure to follow specific reporting guidelines for your area. When reporting, remain calm, speak clearly, and do not exaggerate the facts. If you are unsure about what you are seeing, make your report, but also express your uncertainty. 

Your report should contain the following: 

  • WHO you are: the trained spotter.

  • WHAT you have witnessed: the particular weather event. 

  • WHEN the event occurred: not when you make the report. 

  • WHERE the event occurred: using well-known roads or landmarks.
