  and other lower desert areas, 118-122 for Death Valley and

Drink plenty of fluids...stay in an air-conditioned room...stay
out of the sun...and check up on relatives and neighbors.

is an emergency...call 9 1 1.

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.
