HERE ARE SOME LIGHTNING SAFETY RULES:
ANY LIGHTNING SAFETY PLAN SHOULD INCORPORATE THE 30/30 RULE. THE 30/30 RULE STATES PEOPLE SHOULD SEEK SHELTER IF THE FLASH TO BANG DELAY /LENGTH OF TIME IN SECONDS BETWEEN A LIGHTNING FLASH AND ITS SUBSEQUENT THUNDER/ IS 30 SECONDS OR LESS AND THAT THEY REMAIN UNDER COVER UNTIL 30 MINUTES AFTER THE FINAL CLAP OF THUNDER.
MOVE INSIDE A WELL CONSTRUCTED HOUSE... A LARGE BUILDING... OR AN ALL METAL VEHICLE. STAY AWAY FROM ELECTRICAL APPLIANCES AND DO NOT USE CORDED TELEPHONES.
IF YOU ARE IN A BOAT... GET OFF THE WATER AND INTO A SUBSTANTIAL BUILDING... OR AT LEAST INTO AN ENCLOSED AND ALL-METAL VEHICLE WITH THE WINDOWS UP. IF YOU'RE CAUGHT IN AN OPEN METAL BOAT... LIE DOWN IN THE BOAT WITH CUSHIONS BETWEEN YOU AND THE METAL SIDES AND BOTTOM.
IF YOU ARE CAUGHT OUTDOORS... GET DOWN TO AVOID BEING THE HIGHEST POINT FOR A LIGHTNING DISCHARGE. IF YOU'RE CAUGHT IN A FLAT OPEN FIELD OR IF YOU FEEL YOUR HAIR STANDING ON END... CROUCH DOWN AND COVER YOUR HEAD WITH YOUR HANDS SO THAT ONLY YOUR FEET WILL TOUCH THE GROUND.
MOVE AWAY FROM MOTORCYCLES... SCOOTERS... GOLF CARTS... BICYCLES... TRACTORS... AND OTHER METAL FARM EQUIPMENT. AVOID WIRE FENCES... CLOTHES LINES... METAL PIPES... DRAINS... RAILROAD TRACKS... AND OTHER METALLIC OBJECTS.
AVOID LONE TREES AND THE TALLEST TREES. IF CAUGHT IN THE WOODS... PICK A SMALL GROVE OF TREES AS YOUR SHELTER AND STAND AT LEAST 5 FEET FROM THE TRUNK OF THE NEAREST TREE TO AVOID FLYING BARK IF THE TREE IS STRUCK.
AVOID STANDING IN A SMALL ISOLATED SHED OR OTHER SMALL UNGROUNDED STRUCTURE IN OTHER AREAS.
IF IN A GROUP OF PEOPLE IN AN OPEN AREA... SPREAD OUT BEFORE YOU KNEEL DOWN.
ON WEDNESDAY... A TORNADO DRILL WILL BE CONDUCTED BETWEEN 9 AND 10 A.M.
For the "small-time" weather consumer, lightning data is one piece of weather information that can be hard to come by (especially in realtime). There are only a couple of providers of commercial lightning data in the U.S., which makes re-distributing the data cost-prohibitive for all but the largest commercial vendors. That is why you won't find lightning data on MWN.
However, many times thunderstorms (which just means that a storm has lightning) can be inferred through radar data. MWN's StormView Radar is provided by one of the leading web-radar companies in the south and is, in fact, used by several TV stations for their web-based radar feed. The colors of the returns (or echoes) on a radar map indicate the relative severity of the storm. On StormView Radar, anything colored orange, red, or higher has a fairly high likelihood of containing lightning. As we nowcast on Facebook and Twitter, we'll also be sure to let you know if a storm is electrified so that you may adjust your plans if necessary to maintain your safety.
