FORT MYERS, Fla.- In a matter of days, three Fort Myers city parks will have fully-functioning lightning detectors.

It's the result of an effort championed by a southwest Florida grandmother, who wanted to keep local children safe.

Erleen Sanders was attending her grandson's little league game at the STARS Complex last summer, when a storm came through.  Sanders told WINK News the children were scared and scrambling for shelter.

"It was insane," Sanders said last fall.  "This just can't be happening to us in Florida, the lightning capital of the world."

Since then, Sanders fought to get Weatherbug lightning detectors installed in city parks, replacing the small, handheld devices that were used.

Sanders said her patience has paid off.

"(I'm) greatly relieved and joyful," Sanders said Thursday.

As of last week, a detector is up and running at the Golfview Pool and a second detector was supposed to be installed at the Sam Fleishman Sports Complex.

According to the public works department, wet weather made it difficult for crews to set up equipment on the clay tennis courts at Fleishman.  The department told WINK News that crews will return to install the detector next week.

A third detector is partially installed at the STARS Complex, and is expected to be complete by Feb. 13.

"Better late than never," Sanders said.  "I'm pleased that it's done now, when baseball season is just beginning and so many children will be using the fields."

Sanders said she is talking to members of the Cape Coral City Council about installing the same lightning detectors at their city parks.
