PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE RIVERTON WY
600 AM MDT FRI APR 24 2015

...THIS IS SEVERE WEATHER AWARENESS WEEK IN WYOMING...

THE WEEK OF APRIL 20 TO APRIL 24 HAS BEEN DESIGNATED SEVERE WEATHER
AWARENESS WEEK IN WYOMING. TODAY WE WILL DISCUSS FIRE WEATHER.

WHAT IS FIRE WEATHER AND WHY WOULD IT BE INCLUDED IN SEVERE WEATHER
AWARENESS WEEK?

FIRE WEATHER IS A BROAD TERM USED TO DESCRIBE WEATHER VARIABLES THAT
INFLUENCE FIRE POTENTIAL...BEHAVIOR...AND SUPPRESSION. THE NATIONAL
WEATHER SERVICE ISSUES WATCHES AND WARNINGS WHEN WEATHER VARIABLES
ENCOURAGE EXTREME FIRE BEHAVIOR...JUST LIKE THE NATIONAL WEATHER
SERVICE DOES FOR EXTREME WINTER WEATHER CONDITIONS OR FOR SEVERE
THUNDERSTORMS.

THERE ARE TWO PRODUCTS ISSUED TO WARN OF EXTREME FIRE BEHAVIOR. THE
FIRST IS A FIRE WEATHER WATCH WHICH IS ISSUED WHEN THE WEATHER IS
EXPECTED TO ENCOURAGE EXTREME FIRE BEHAVIOR A COUPLE OF DAYS FROM
NOW...AND IT IS OFTEN UPGRADED TO WHAT IS KNOWN AS A RED FLAG WARNING
ONCE THE TIME OF THE ANTICIPATED CONDITIONS DRAWS CLOSER.

WHEN IS A RED FLAG WARNING ISSUED?

THE MAIN TWO WEATHER ELEMENTS THAT ENCOURAGE EXPLOSIVE FIRE GROWTH
IS VERY LOW RELATIVE HUMIDITY AND BREEZY WINDS. HUMIDITY BELOW 15
PERCENT IN COMBINATION WITH GUSTY WINDS ABOVE 25 MPH...HAVE SHOWN TO
RESULT IN EXPLOSIVE FIRE GROWTH WHEN FUELS ARE CRITICAL. IF THESE
CONDITIONS ARE EXPECTED THEN A RED FLAG WARNING IS ISSUED WITHIN 24
HOURS OF THE EVENT.

A RED FLAG WARNING WILL ALSO BE ISSUED WHEN THUNDERSTORMS WITH
LITTLE OR NO RAINFALL ARE EXPECTED WHEN FUELS ARE CRITICAL. DRY
THUNDERSTORMS CAN INITIATE MULTIPLE NEW FIRE STARTS...WHICH CAN TAX
FIRE FIGHTING RESOURCES.

IF A RED FLAG WARNING IS ISSUED FOR YOUR AREA...THIS IS YOUR SIGNAL
TO BE EVEN MORE CAUTIOUS WITH FIRE.

WILDFIRES CAN BE STARTED BY THE SLIGHTEST SPARK...EVEN FROM SOMETHING
AS PERCEPTIVELY HARMLESS AS PARKING AN ATV IN THE GRASS...THE WARM
MUFFLER MAY START A GRASS FIRE.

CHECK FOR CURRENT BURN BANS FOR YOUR COUNTY...AND PLEASE TAKE
THEM SERIOUSLY. IF YOU PLAN ON DOING SOME AGRICULTURAL BURNING...
PLEASE NOTIFY YOUR LOCAL SHERIFF AND FIRE DEPARTMENT TO ENSURE THAT
IT IS LEGAL AND THAT YOU DO NOT CAUSE ANY FALSE ALARM CALLS.

ALSO PLEASE CALL THE NATIONAL WEATHER SERVICE AT 800-211-1448 FOR A
FORECAST FIRST SO THAT YOU ENSURE THAT RED FLAG CONDITIONS WILL NOT
DEVELOP AND CAUSE YOUR FIRE TO BECOME UNCONTROLLABLE.

...THIS IS SEVERE WEATHER AWARENESS WEEK IN WYOMING...

THE WEEK OF APRIL 20 TO APRIL 24 HAS BEEN DESIGNATED SEVERE WEATHER
AWARENESS WEEK IN WYOMING. TODAY WE WILL DISCUSS LIGHTNING SAFETY...
AND WAYS TO RECEIVE NATIONAL WEATHER SERVICE (NWS) PRODUCTS AND
SERVICES.

...LIGHTNING...

THERE HAVE BEEN 5 LIGHTNING DEATHS AND 62 INJURIES SINCE 2000 IN
WYOMING. LIGHTNING IS RANKED FIRST IN SEVERE WEATHER RELATED
FATALITIES AND INJURIES IN WYOMING FROM 2000 TO PRESENT.

LIGHTNING...BY DEFINITION...OCCURS WITH EVERY THUNDERSTORM.
THUNDERSTORMS TYPICALLY IMPACT THE COWBOY STATE FROM APRIL THROUGH
OCTOBER PEAKING IN LATE SPRING INTO EARLY SUMMER...WITH A SECONDARY
PEAK DURING THE MONSOON IN AUGUST. LIGHTNING IS ONE OF THE DEADLIEST
WEATHER PHENOMENON. MOST LIGHTNING FATALITIES AND INJURIES IN
WYOMING OCCUR IN THE MOUNTAINS...BUT ANYWHERE OUTSIDE IS VULNERABLE
TO LIGHTNING.

LIGHTNING SAFETY BEGINS WITH KNOWING THE WEATHER FORECAST
AND WATCHING FOR APPROACHING STORMS. IF THUNDERSTORMS ARE
IMMINENT...POSTPONE OUTDOOR ACTIVITIES UNTIL THE THUNDERSTORMS PASS.
THIS IS YOUR BEST WAY TO AVOID BEING CAUGHT IN A DANGEROUS SITUATION.
HOWEVER IF YOU ARE OUTSIDE AND HEAR THUNDER...SEEK SHELTER
IMMEDIATELY IN A STURDY BUILDING.  IF A STURDY BUILDING IS NOT
AVAILABLE...TAKE SHELTER IN A HARD TOPPED VEHICLE. DO NOT SEEK
SHELTER IN SMALL SHEDS...UNDER ISOLATED TREES OR IN A SOFT TOPPED
CONVERTIBLE AUTOMOBILE. IF CAUGHT OUTDOORS AND NO SHELTER IS
NEARBY...FIND A LOW SPOT AWAY FROM TREES...FENCES AND POLES. IF YOU
ARE BOATING...GET TO LAND AND FIND SHELTER IMMEDIATELY. WHEN THUNDER
ROARS...GO INDOORS!
