HEALTH INFORMATION...If smoke is thick or becomes thick in your
neighborhood you may want to remain indoors. This is especially
true for those with heart disease, respiratory illnesses, the very
young, and older adults. Consider limiting outdoor activity when
moderate to heavy smoke is present. Consider relocating
temporarily if smoke is present indoors and is making you ill. If
visibility is less than 5 miles in smoke in your neighborhood,
smoke has reached levels that are unhealthy.
