...WHEN THUNDER ROARS...GO INDOORS...

THUNDERSTORMS PRODUCE SOME OF THE MOST DANGEROUS WEATHER ON EARTH...
INCLUDING TORNADOES...FLASH FLOODS...LARGE HAIL...AND DESTRUCTIVE
STRAIGHT LINE WINDS. HOWEVER...THE MOST DANGEROUS ASPECT OF
THUNDERSTORMS IN COLORADO IS USUALLY LIGHTNING.

IN ADDITION TO PRODUCING HUMAN CASUALTIES...LIGHTNING ALSO IGNITES
MOST FOREST AND RANGELAND FIRES IN THE CENTENNIAL STATE. MANY OF
THESE WILDFIRES OCCUR WHEN LIGHTNING IS GENERATED FROM
THUNDERSTORMS WHICH PRODUCE LITTLE OR NO RAINFALL.

WHEN LIGHTNING THREATENS...GET TO A SAFE SHELTER AS QUICKLY AS
POSSIBLE. SAFE SHELTERS INCLUDE SUBSTANTIAL FULLY ENCLOSED
BUILDINGS...SUCH AS HOUSES...CHURCHES,,,OR STORES...AS WELL AS
VEHICLES WITH METAL ROOFS. ONCE INSIDE A SUBSTANTIAL BUILDING OR
METAL TOPPED VEHICLE...KEEP ALL WINDOWS AND DOORS CLOSED...SINCE
LIGHTNING CAN PASS THROUGH AN OPEN AIRWAY.
