* WHAT...Heat index values up to 98. * WHERE...In Delaware, New Castle County. In Pennsylvania, Eastern Chester County. * WHEN...Until 8 PM EDT Wednesday. * IMPACTS...Hot temperatures and high humidity may cause heat illnesses. * ADDITIONAL DETAILS...Record setting high temperatures are quite possible through Wednesday, with maximum heat indices nearing 100 degrees during peak heating each afternoon. Given the intensity of this early season stretch of heat and humidity, we are not acclimated to it yet and therefore impacts could be greater if precautions are not taken. Showers and some thunderstorms arrive later Wednesday afternoon and evening which will break this early season heat.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
