IF device_XYZ is a mobile weather station
is located in zone_000 average wind speed is
greater than 40 average temperature is
greater than 5 weather forecast announces
high avalanche hazard THEN zone_000 is a
dangerous zone
IF ski_run_123 is a slope is located in
a dangerous zone THEN lock ski_run_123
IF boat_471 is a small boat is located in
zone_123 is available has capacity for
more than 4 passengers THEN boat_471 can
evacuate people from zone_123
