...HEAT ADVISORY IN EFFECT UNTIL 8 AM EDT WEDNESDAY...
...EXCESSIVE HEAT WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH THURSDAY EVENING...

* WHAT...For the Heat Advisory, heat index values near 100. For the Excessive Heat Watch, dangerously hot conditions with heat index values possibly exceeding 100 degrees.

* WHERE...Genesee, Lapeer, Livingston, Oakland, Macomb, Washtenaw, Wayne and Monroe Counties.

* WHEN...For the Heat Advisory, until 8 AM EDT Wednesday. For the Excessive Heat Watch, from Wednesday morning through
Thursday evening.

* IMPACTS...Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities, or those
vulnerable to heat stress over several days.

* ADDITIONAL DETAILS... High temperatures once again exceed 90 degrees today, for the 6th day in a row at Detroit and Flint, and for the second day in a row with high humidity. Scattered to numerous showers and thunderstorms bring little relief as wet ground only adds to humidity while temperatures barely settle to lows around 70 tonight. This is followed by the peak of conditions Wednesday and Thursday with high temperatures in the mid 90s and heat index possibly exceeding 100. The cumulative impact on heat health stress is expected to be considerable and could require an Excessive Heat Warning until a cold front moves into the area by Friday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Monitor the latest forecasts and warnings for updates on this situation. Be prepared to 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.
