... Heat advisory now in effect until 7 PM CDT Wednesday...
* afternoon temperatures in the lower 90s combined with oppressive
humidity levels will produce heat index values in the 105 to 110
degree range late this afternoon and again on Wednesday
afternoon. The advisory is in effect generally along and east of
a line from Mount Vernon Illinois to the Land Between The Lakes
area. West of this line an excessive heat warning is in effect
today. Please refer to the warning for additional details.
* A heat index of 105 is generally considered the threshold
where the body begins to succumb to the effects of the heat...
making heat exhaustion and heat stroke a greater concern if
precautions are not taken.
A heat advisory means that a period of hot temperatures and high
humidity levels are expected. This combination will create a
situation in which heat illnesses are possible. If you work or
plan to spend much time outside... take frequent breaks and drink
plenty of fluids. If possible... stay in an air-conditioned
environment... stay out of the sun as much as possible... and check
up on relatives and neighbors.
