---------------------------------------------------------------------
YELLOW LEVEL WARNING - HEAT - FOR:
=NEW= OKANAGAN VALLEY
=NEW= FRASER CANYON - NORTH INCLUDING LILLOOET
=NEW= SOUTH THOMPSON
=NEW= SHUSWAP.
---------------------------------------------------------------------
IMPACT LEVEL: MODERATE

==DISCUSSION==
THIS IS A HEAT WARNING. TEMPERATURES ARE HIGH AND THERE'S A RISK TO
PUBLIC HEALTH.
WHAT:
DAYTIME HIGHS IN THE MID TO HIGH THIRTIES COMBINED WITH OVERNIGHT
LOWS IN THE HIGH TEENS.
WHEN:
TODAY TO THURSDAY.
WHERE:
OKANAGAN VALLEY, LILLOOET, SOUTH THOMPSON, SHUSWAP
ADDITIONAL INFORMATION:
HUMIDEX VALUES MAY APPROACH THE HIGH THIRTIES ON THURSDAY OVER THE
OKANAGAN VALLEY AND SHUSWAP AS A SOUTHERLY FLOW BRINGS MORE MOISTURE
INTO THE AREAS, INCREASING THE HUMIDITY.
HEAT AFFECTS EVERYONE, BUT THE RISKS ARE GREATER FOR: SENIORS,
PEOPLE WHO LIVE ALONE, PEOPLE WITH PRE-EXISTING HEALTH CONDITIONS
SUCH AS DIABETES, HEART DISEASE OR RESPIRATORY DISEASE, PEOPLE WITH
MENTAL ILLNESS SUCH AS SCHIZOPHRENIA, DEPRESSION, OR ANXIETY, PEOPLE
WITH SUBSTANCE USE DISORDERS, PEOPLE WITH LIMITED MOBILITY.
CHECK ON FAMILY, FRIENDS AND NEIGHBOURS, WHO ARE AT HIGHER RISK,
PARTICULARLY IF THEY LIVE ALONE, TO MAKE SURE THEY HAVE A COOL
SPACE.
WATCH FOR EARLY SIGNS OF HEAT ILLNESS (FEELING UNWELL, FATIGUE,
THIRST, HEADACHE, UNUSUALLY DARK URINE) AS THESE CAN RAPIDLY EVOLVE
INTO LIFE-THREATENING EMERGENCIES.
MOVE TO A COOLER ENVIRONMENT IMMEDIATELY, SUCH AS A SHADED OR
AIR-CONDITIONED SPACE.
DRINK PLENTY OF WATER REGULARLY, EVEN BEFORE YOU FEEL THIRSTY TO
DECREASE YOUR RISK OF DEHYDRATION. THIRST IS NOT A GOOD INDICATOR OF
DEHYDRATION.
NEVER LEAVE SUSCEPTIBLE PEOPLE, PARTICULARLY CHILDREN, OR PETS
INSIDE A PARKED VEHICLE.
IF YOU ARE IN AN OVERHEATED AREA, SEEK A COOL PLACE SUCH AS A
TREE-SHADED AREA, SPLASH PAD, MISTING STATION, OR AIR-CONDITIONED
SPOT LIKE A PUBLIC BUILDING.
