Lightning Prediction System

The Recreation Services Department has installed LIGHTNING PREDICTION SYSTEMS at several parks throughout the City.  All machines have been activated on Friday, August 10, 2007.  When these machines detect a lightning strike possibility in close proximity, they sound an alert horn, and a strobe light begins flashing.  When the probability of a nearby lightning strike ceases, the machine sounds an “all clear”.

Signage will be displayed with the following message:

THIS PARK HAS BEEN EQUIPPED WITH AN AUDIBLE AND VISUAL LIGHTNING WARNING SYSTEM

Lightning is a deadly hazard that must be respected.  Everyone should immediately seek shelter any time they believe lightning threatens them, even if a signal has not been heard.

A warning from our electronic lightning prediction system, will be indicated by the sound of one 15 second blast of the horn (also indicated by a flashing strobe light on the unit).  This will signal the suspension of all park activities.  You should immediately seek an appropriate, safe shelter.

You may resume activities only after three 5-second blasts of the horn have sounded and the strobe light stops flashing.

USE OF THIS PARK IS AT YOUR OWN RISK.  THE CITY CANNOT GUARANTEE THE EFFECTIVENESS OF THE WARNING SYSTEM.  IF YOU SEE LIGHTNING ANYWHERE NEAR THE AREA, YOU ARE ADVISED TO TAKE SHELTER IMMEDIATELY UNTIL THE THREAT HAS PASSED.

The following parks are equipped with this system:

  • deHoernle
  • Hillsboro/El Rio
  • Lake Wyman
  • Meadows
  • Memorial
  • Patch Reef Park
  • Sand Pine
  • Sugar Sand
  • Swim & Racquet Center

USE OF THIS PARK IS AT YOUR OWN RISK.  THIS PARK IS NOT PROTECTED BY A LIGHTNING WARNING SYSTEM.  IF YOU SEE LIGHTNING ANYWHERE NEAR THE AREA, YOU ARE ADVISED TO TAKE SHELTER IMMEDIATELY UNTIL THE THREAT HAS PASSED.
