JACKSONVILLE, Fla. -- Action News walked the path of the storm with our local National Weather Service crew.
Al Sandrik knew with just a single glance how serious this storm was.
"You think this was a tornado?" reporter Kristen Sell asked him as they walked. "Oh yeah. I've seen enough tornadoes. This was definitely a tornado," he said.
The crew stopped every few feet to survey the aftermath. Sandrik said wind speeds from this EF-2 likely topped 120 miles per hour.
He's documenting the damage instantaneously with an app on his iPhone.
"It's called a damage assessment tool. It has all of the information we need to go along and do an assessment of a storm like this," he said.
He went up to the destruction and pointed the phone. It calculated the wind speed and gives gave it a GPS location. After walking the perimeter, he was left with one positive.
"We got lucky that people didn't get hurt. We had a severe thunderstorm warning out, but some of these systems are very, very hard to see on the radar. They spin up very, very quickly," he said. "The tornado is down, and gone."
The National Weather Service crew has 60 days to determine what the tornado's actual intensity was. It'll then add all itsfindings into the permanent national record.
