The Upstate has been a bit stormier than usual this summer.

“The last two to three weeks, nearly every afternoon, we’ve had severe storms come through the county and they’ve been more severe and numerous than ever,” said Doug Bryson, director of the Spartanburg County Office of Emergency Management.

Afternoon storms are in the forecast again this week through the weekend. Although that isn’t unusual for July in Spartanburg, there have been more severe storm warnings than in previous years, according to meteorologist Jeffrey Taylor of the National Weather Service at Greer.

“It’s been fairly busy thus far,” Taylor said. “But we’ve had summers where we’ve issued more warnings. This summer is not unprecedented.”

What’s causing the increased chances for afternoon pop-up storms is an abundance of tropical moisture in the Southeast. With daytime heating, storms form and some can become severe, although most storms die out in 35 to 40 minutes and affect a limited area, he said.

“They can produce locally severe weather,” Taylor said.

Typically the summer weather patterns keep cold fronts well to the north, but already some have dipped through the state, also helping to trigger strong storms, hail, strong winds and heavy rainfall, he said.

Meanwhile, already this hurricane season there have been three named storms, the latest being Chris off the Carolina coast that was not forecast to make landfall.

The National Hurricane Center has predicted an above-normal season with 10 to 16 named storms with winds of 39 mph or higher, five to nine of which could become hurricanes with winds of 74 mph or higher, including one to four major hurricanes with winds of 11 mph or higher.

An average hurricane produces 12 named storms, of which six become hurricanes — and three become major hurricanes. The season runs June 1 to Nov. 30.

Taylor said just because an above-normal season is expected, it doesn’t mean that any will make landfall. Predicting a hurricane will hit the United States that far in advance is still nearly impossible even with all of today's technological advances, he said.

Bryson said of those that do make landfall, the ones that come up from the Gulf of Mexico are far more likely to affect the Upstate than ones that come in from the Atlantic Ocean.

Such was the case in late May — even before the start of hurricane season — when remnants from Subtropical Storm Alberto drenched the Upstate and mountains of western North Carolina, where flash flooding and landslides occurred.

Whether it be tropical storms, tornadoes or hurricanes, Bryson said he’s always monitoring the weather so he can notify first responders and utility companies. First responders include police and sheriff’s offices, fire departments, emergency medical services and the Department of Transportation crews.

“You never know exactly where they’re going to hit,” he said of damaging storms. “The big thing is we take these warnings and notifications very seriously. We don’t send them out unless we absolutely have to. We would always (rather) err on over-warning than under-warning — than people get property damage or people get hurt.”
