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.
