...High heat index values expected today...

Very warm temperatures coupled with high humidity will produce
heat index values between 103 and 107 degrees. Heat index values
may be highest along the coast with higher humidity. A heat
advisory may yet be required later today if heat index values of
108 or higher become likely. Heat index values should be lower
Monday and Tuesday with increased cloud cover due to shower and
thunderstorm activity. This may limit high temperatures to the mid
90s instead of the upper 90s.

Whether or not heat advisories are issued, you need to protect
yourself and others from the impacts of the heat. If outside, stay
hydrated, take breaks in the shade as often as possible and limit
strenuous activities. If driving, never leave kids, pets or
anyone with limited mobility alone in a vehicle for even a few
minutes as rapidly rising temperatures could reach dangerous or
even deadly levels. Remember to look before you lock! Know the
signs of heat stress and seek medical attention if you suspect
that you or someone else is experiencing heat illness.
