COLLIER COUNTY, Fla. - Lightning is a huge concern for residents and guests of Collier County. Barry Williams, the Director of the County's Parks and Recreation department said lightning prediction and detection systems are already in place at three of the county's large parks.

"We have tournaments that play here, a couple thousand on the fields, you want them to know when there's lightning in the area," said Williams.

And that's the job of Thor Guard. This system measures the electrostatic in the atmosphere, then warns people of lightning. It helps Derek Renauld do his job at the Sun-N-Fun Lagoon inside North Collier Regional Park.

"The advantage of having technology to help us with that is our eyes can constantly be on the water," said Renauld.

The technology is also installed at Veterans and Vineyards parks. The county wants to add more of these detection systems to more parks. It costs taxpayers $15,000 to to pay for and install one of these systems. It will soon be found at a new community center in East Naples.

"That project, that park will be built in the next few months so we will be installing it in there as well," said Williams.

And parents said it's worth it.

'It makes me feel more safe with my three girls," said Scott Smith.

Williams said a lot of their sites are shared with the School District and those sites already have lightning detection systems.
