PERIOD. THE OVERNIGHT LOW TEMPERATURES WILL REMAIN RATHER WARM AS
WELL WITH TEMPERATURES IN THE FOOTHILLS AND MOUNTAINS IN THE LOWER
TO MID 70S. IN ADDITION...TROPICAL MOISTURE MOVING ACROSS THE AREA
FROM MEXICO WILL CAUSE INCREASING HUMIDITY AND RISING HEAT INDEX

THIS EXTENDED PERIOD OF HOT WEATHER COMBINED WITH RISING HUMIDITY

RELATED IMPACTS. WHEN POSSIBLE...RESCHEDULE STRENUOUS ACTIVITIES
TO EARLY MORNING OR EVENING. WEAR LIGHTWEIGHT AND LOOSE-FITTING
CLOTHING WHEN POSSIBLE AND DRINK PLENTY OF WATER. NEVER LEAVE
CHILDREN...THE ELDERLY...OR PETS IN ENCLOSED AUTOMOBILES EVEN FOR
A SHORT PERIOD OF TIME.

WITH THE HOT TEMPERATURES THIS WEEKEND...DRY CONDITIONS WILL PREVAIL
AWAY FROM THE COAST. THIS WILL RESULT IN ELEVATED FIRE DANGER IN
SOUTHWESTERN CALIFORNIA DUE TO THE CRITICALLY DRY VEGETATION ACROSS
THE REGION.
