Severe Thunderstorms & Tornadoes: What Rowan County Needs to Know

As part of Severe Weather Preparedness Week in North Carolina, today’s focus is on severe thunderstorms and tornadoes — two of the most dangerous spring weather threats we face here in Rowan County.

Understanding how these storms work — and how alerts are issued — can help you make faster, safer decisions when warnings are issued.

What Makes a Thunderstorm “Severe”?

Not every thunderstorm is considered severe.

A storm officially becomes severe when it produces one or more of the following:

• Wind gusts of 58 mph or stronger

• Hail 1 inch in diameter or larger (about the size of a quarter)

• A tornado

Severe thunderstorms can also produce intense lightning, torrential rain, and localized flash flooding — even if they don’t meet official severe criteria.

In Rowan County, severe storms are most common in the spring and early summer, but they can happen any time of year.

How Do Tornadoes Form?

Tornadoes develop from powerful thunderstorms, typically from a type called a supercell thunderstorm.

Here’s the simple breakdown:

1. Warm, moist air near the ground rises.

2. Cooler, drier air sinks.

3. Strong winds at different heights begin to rotate.

4. That rotation can tighten and intensify.

5. If it reaches the ground — a tornado forms.

North Carolina averages dozens of tornadoes each year. While many are brief and weaker, some can be strong and long-lasting.

Watch vs. Warning: What’s the Difference?

This is one of the most important things to understand.

Tornado Watch

• Conditions are favorable for tornadoes.

• Stay alert.

• Review your plan.

• Be ready to move quickly.

Tornado Warning

• A tornado has been detected by radar or confirmed by spotters.

• Take shelter immediately.

• Move to your safe place without delay.

The same concept applies to Severe Thunderstorm Watches and Warnings.

A Watch means “be prepared.”
A Warning means “take action.”

Why Rowan County Can See Both Spin-Up and Long-Track Tornadoes

Rowan County sits in the North Carolina Piedmont, where we can experience different types of tornadoes.

Spin-Up Tornadoes

These are often brief and can develop quickly along lines of strong storms. They may:

• Form with little lead time

• Be short-lived

• Cause localized damage

Long-Track Tornadoes

These are typically associated with stronger, organized storm systems. They can:

• Stay on the ground for miles

• Produce more significant damage

• Impact multiple counties

Our location between the mountains and the coastal plain allows us to experience both types depending on the setup.

What You Should Do Now

Before the next storm develops:

• Identify your safe place (lowest level, interior room, away from windows).

• Make sure you have multiple ways to receive warnings.

• Talk with your family about what to do when a warning is issued.

• Practice moving to your safe location quickly.

Preparation now means fewer decisions when seconds matter.

Tomorrow, we’ll focus on how to receive severe weather alerts and provide details about the statewide tornado drill happening this week.

Stay weather aware, Rowan County.
