  1. Storm Surge: An abnormal rise of the sea along a shore as a result, primarily, of the winds from a storm.
  2. Watch: Adverse conditions are possible in the specified area of the WATCH, usually within 36 hours. May be applied to thunderstorms, tornadoes, floods, or hurricanes.
  3. Warning: Adverse conditions are expected in the specified area of the WARNING, usually within 24 hours. May be applied to thunderstorms, tornadoes, floods, or hurricanes.
