ATLANTA (CBS46) -

A rare high wind warning was briefly issued for Atlanta Thursday night.

Such warnings are only issued if there are sustained winds of 40 mph, or wind gusts of 58 mph. The warning is basically issued for severe thunderstorm winds without the actual storm.

How rare?

The high wind warning was the first such warning issued in Atlanta since at least 2000, according to Kent Frantz at the National Weather Service in Peachtree City. That's more than 15 years! 

Wind gusts over 60 mph

The warning lasted for about an hour and a half after very high wind speeds were seen in  Atlanta, including a 60 mph wind gust on our exclusive WeatherBug Network. The high winds caused several trees to fall throughout metro Atlanta. 

Why so strong?

The reason for the brief, strong wind is actually quite simple.

Wind is simply air flowing from high to low pressure. Most of the time, highs and lows are pretty far away from each other, creating low wind speeds that we barely notice. But on Thursday night, a small area of high and low pressure developed right over metro Atlanta! Since they were so close to each other, the wind between them flowed faster, producing a brief period of unusually high winds.
