crests do not break. | Wind felt on face; leaves rustle; wind vanes move. | | **3** | **Gentle Breeze** | 7–10 knots, 8–12 mph, 12–19 km/h | 2–4 ft, 0.6–1.2 m | Large wavelets; crests break; foam of glassy appearance; perhaps scattered white horses. | Leaves and small twigs in constant motion; light flags extended. | | **4** | **Moderate Breeze** | 11–16 knots, 13–18 mph, 20–28 km/h | 3.5–6 ft, 1–2 m | Small waves; frequent white horses. | Raised dust and loose paper; small branches moved. | | **5** | **Fresh Breeze** | 17–21 knots, 19–24 mph, 29–38 km/h | 6–10 ft, 2–3 m | Moderate waves; many white horses and chance of spray. | Small leafy trees sway; crested wavelets form on inland waters. | | **6** | **Strong Breeze** | 22–27 knots, 25–31 mph, 39–49 km/h | 9–13 ft, 3–4 m | Large waves; white foam crests; spray. | Large branches in motion; whistling heard in telegraph wires; umbrellas used with difficulty. | | **7** | **Moderate Gale** | 28–33 knots, 32–38 mph, 50–61 km/h | 13–19 ft, 4–5.5 m | Sea heaps up; white foam and spindrift from breaking waves. | Whole trees in motion; walking against wind requires effort. | | **8** | **Gale** | 34–40 knots, 39–46 mph, 62–74 km/h | 18–25 ft, 5.5–7.5 m | High, long waves; edges of crests break into spindrift; foam is blown in well-marked streaks along the direction of the wind. | Twigs break off trees; walking is difficult. | | **9** | **Strong Gale** | 41–47 knots, 47–54 mph, 75–88 km/h | 23–32 ft, 7–10 m | High, rolling waves; dense streaks of foam; spray affects visibility. | Slight structural damage (chimneys and roofs). | | **10** | **Storm** | 48–55 knots, 55–63 mph, 89–102 km/h | 29–41 ft, 9–12.5 m | Very high waves with long overhanging crests; dense foam in great patches; heavy rolling sea. | Seldom experienced inland; trees uprooted; considerable structural damage. | | **11** | **Violent Storm** | 56–63 knots, 64–72 mph, 103–117 km/h | 37–52 ft, 11.5–16 m | Exceptionally high waves; small and medium ships lost to view; sea covered with long white patches of foam. | Rarely experienced inland; widespread damage. | | **12** | **Hurricane** | > 64 knots, > 73 mph, > 118 km/h | = 46 ft, = 14 m | Air filled with foam and spray; sea completely white with driving spray; visibility almost zero. | Devastation. | _Source:_ with some changes made by Johnn. ## Example Game Effects | Force | Name | Dangers | Environment | Ranged Attacks | Visibility | Communication | | --- | --- | --- | --- | --- | --- | --- | | **0** | Calm | None | Torches burn straight. | Normal | Normal | Normal | | **1** | Light air | None | Candle flames flicker slightly. | Normal | Normal | Normal | | **2** | Light breeze | None | Leaves rustle;
