  possible with overnight low temperatures at or above 75 degrees.

* WHERE...Portions of northern Indiana, southwest Michigan, and
  northwest Ohio.

* WHEN...Heat Advisory until 8 AM EDT Sunday. Extreme Heat Watch

* IMPACTS...Heat related illnesses increase significantly during
  extreme heat and high humidity events. Hot temperatures and high
  humidity may cause heat illnesses.

* ADDITIONAL DETAILS...Cumulative effects of long-duration heat will

  little relief, especially for vulnerable populations.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

Monitor the latest forecasts and warnings for updates.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks in
shaded or air conditioned environments. Anyone overcome by heat
should be moved to a cool and shaded location. Heat stroke is an
emergency! Call 9 1 1.
