providing little chance for relief. This combination will create
a dangerous situation in which heat-related illnesses are
likely... especially for those living in un-air conditioned homes
or apartments. People in the warning area are advised to avoid
poorly ventilated areas and prolonged work in the sun. Use air
conditioning in your house or apartment if it is working
correctly. If you do not have air conditioning... keep your house
or apartment well ventilated with fans... and try to spend some
time in an air conditioned environment to give your body a break
from the heat.
