When thunder is audible, danger exists. Embrace the 30–30 rule: seek a safe enclosure if flash-to-bang is thirty seconds or less, then wait thirty minutes after the last rumble. Avoid isolated trees, fence lines, and hilltops. Spread the group, crouch minimally if caught outside, and remember vehicles offer excellent protection. Phones help with alerts, not invincibility, so move early.
Hail cores ride dark, rain-wrapped shafts near storm centers. Pair radar with visual cues, then pivot toward robust structures—visitor centers, vehicles, or substantial shelters—rather than flimsy rest stops. Cyclists should protect helmets and hands; hikers guard eyes and joints. Keep entrances clear of windward debris, anchor anything loose, and maintain morale with quick calories as the turbulence briefly roars.
Outflow boundaries can slam camps with sudden microbursts, flipping unsecured tents. Stake guylines aggressively, choose ground with good drainage, and face doors leeward. If dusty walls advance, goggles and buffs protect eyes and lungs. Keep electronics sealed, decide whether to ride it out or retreat early, and map safer windbreaks like embankments or sturdy buildings before squalls surge.
