Powerful Storms

Very high winds and torrential precipitation reduce visibility to zero and can make Perception checks and ranged weapon attacks difficult. Powerful storms are divided into the following types.

• Blizzard: The combination of high winds, heavy snow (typically 1d4 feet), and extreme cold make blizzards deadly for those unprepared for them.
• Hurricane: In addition to very high winds and heavy rain, hurricanes are accompanied by floods. Most adventuring activity is extremely difficult under such conditions.
• Tornado: With incredibly high winds, tornadoes can severely injure and kill creatures pulled into their funnels.
• Windstorm: While accompanied by little or no precipitation, windstorms can cause considerable damage simply through the force of their winds (see Winds below).
