PLAIN...ESPECIALLY THOSE THAT DO NOT HAVE AIR CONDITIONING.
VERY WARM OVERNIGHT LOWS IN THE 70S TO LOWER 80S CAN BE EXPECTED

HEAT DISCOMFORT.

THE GUSTY SANTA ANA WINDS WILL ALSO BRING WIDESPREAD HUMIDITIES

CONDITIONS COMBINED WITH THE EXTREMELY DRY FUELS WILL PLACE MUCH
OF LOS ANGELES AND VENTURA COUNTIES UNDER EXTREME FIRE DANGER
THROUGH MONDAY. FOR MORE DETAILS...PLEASE REFER TO THE LATEST RED
FLAG WARNING PRODUCT.

THE HOT TEMPERATURES WILL CREATE A SITUATION IN WHICH HEAT
ILLNESSES WILL BE POSSIBLE...ESPECIALLY FOR THE ELDERLY AND
CHILDREN. DRINK PLENTY OF FLUIDS...STAY OUT OF THE SUN DURING PEAK
HEATING...AND NEVER LEAVE KIDS OR PETS IN VEHICLES AS TEMPERATURES
CAN QUICKLY REACH VERY DANGEROUS LEVELS.
