* WHAT. Dangerously hot conditions with heat index values up to 100 possible. * WHERE. Portions of central, south central, southwest, and west central Michigan. * WHEN.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has declared an Air Quality Advisory for Monday, June 17, for elevated levels of ozone in parts of southwest Michigan. Pollutants within those areas are expected to be in the Unhealthy for Sensitive Groups (USG, Orange AQI) range. The Air Quality Advisory is in effect for the following counties in southwest Michigan. Berrien and Cass Temperatures and humidity will continue to increase as we begin the new week. Temperatures in the 90's and dewpoints around 70 degrees will add to the misery index for the week. This pattern looks to persist through the week. With winds at all levels of the atmosphere coming from the hot southwest, Air Quality will certainly be an issue, this week. With conditions not expected to change, drink plenty of fluids, stay in an air-conditioned room, stay out of the sun as much as possible, and check up on relatives and neighbors. It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with respiratory diseases such as asthma. People and businesses are urged to avoid activities which lead to ozone formation. These activities include: * refueling vehicles or topping off when refueling; * using gasoline powered lawn equipment; * using charcoal lighter fluid. Positive activities include: * driving less; * telecommuting; * and delaying or combining errands.

* WHAT. Dangerously hot conditions with heat index values around 100 degrees. * WHERE. Portions of northern Indiana, southwest Michigan and northwest Ohio. * WHEN. From Monday morning through Friday evening. * IMPACTS. Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. A lack of cooling overnight will increase impacts on the body as well for those lacking sufficient means of cooling. * ADDITIONAL DETAILS. Heat indices into the mid to upper 90s are possible next weekend beyond the time of the watch. The prolonged nature of the event may magnify impacts as we move into the latter portions of the week. In addition, widely scattered showers and storms Monday and Tuesday could limit the heat impacts in some areas.
