Special Weather Statement

Special Weather Statement issued June 9 at 2:29PM EDT by NWS Indianapolis IN
Jun 9, 2:29 PM Jun 10, 4:00 AM
Early season heat is upon us, with forecasted high temperatures
for Wednesday and Thursday in the upper 80s to lower 90s. Gulf
moisture surging northward into the state will bring heat indices
into the 95 to 104-degree temperature range during peak heating
both days.

Use the following safety tips for facing the heat safely:

* Stay hydrated, avoiding alcohol and drinks with heavy
caffeine or sugar.
* Dress in loose fitting clothing, light in color.
* Take advantage of shade and air conditioning when possible.
* Take frequent breaks when working outdoors.
* Beware that automobiles heat up very quickly, thus pets and
children should not be left in parked vehicles for any length
of time.
* Vulnerable populations are particularly at risk: elderly,
infants, and people with chronic medical conditions.
