Who to call, before and after

The hazards South Carolina actually faces

• Hurricane and storm surge

  Peak season: Sep

  Storm surge, not wind, is the deadliest part of a hurricane for most coastal households — it can arrive hours before landfall and reach well inland of any beachfront. Evacuation zones are set by surge modeling, not by category number, which is why a weaker storm on a bad track can flood a zone a stronger storm on a better track never touches. Knowing your zone before the season, not during the warning, is the single highest-leverage step.

• Extreme rainfall and flash flood

  Peak season: Sep–Oct

  Flash flooding is the deadliest hazard tied to rainfall, and most of those deaths are people driving into water they underestimated — six inches of moving water can stall a car, twelve can float one. Rainfall intensity, not just total inches, is what overwhelms storm drains and low-lying roads in a window of an hour or less.

• Hail and derecho

  Peak season: Apr–Jul

  Hail and derecho winds arrive inside the same thunderstorm complex, often with less lead time than a tornado warning because the threat is the whole storm line, not a single funnel. Large hail totals more property-damage claims nationally than any other severe-storm hazard, and derecho wind gusts can match hurricane-force winds hundreds of miles from open water. Vehicles under cover and loose yard items secured before the line arrives are the cheap fix.

Rules worth knowing
