When do northern splash pads close for storms?

Splash pads in storm-prone northern climates follow strict severe-weather protocols. Lightning is the primary trigger — the National Lightning Safety Council's 30-30 rule says close immediately when thunder follows lightning by less than 30 seconds (within 6 miles), and stay closed until 30 minutes after the last thunder. Many automated systems use lightning detectors with 10-mile thresholds. Other triggers: tornado watches and warnings (immediate closure), severe thunderstorm warnings, hail of any size, sustained winds over 35 mph that turn spray into airborne hazards. Heavy rain alone usually doesn't close pads but will if it overwhelms drainage. Reopening varies — small pads may flip back on within an hour, while large facilities may close for the day after major storm damage.
