Precautionary/preparedness actions... 

An excessive heat watch means that a prolonged period of hot
temperatures is expected. The combination of hot temperatures and
high humidity will combine to create a dangerous situation in
which heat illnesses are possible. Drink plenty of fluids... stay
in an air-conditioned room... stay out of the sun... and check up
on relatives and neighbors.

Young children and pets should never be left unattended in
vehicles under any circumstances.  This is especially true during
warm or hot weather when car interiors can reach lethal
temperatures in a matter of minutes.
