The advisory, which began Sunday afternoon, will remain in effect until 8:00 PM Wednesday.\n\n&#8220;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,&#8221; the Weather Service warned. Record-setting high temperatures are possible through Wednesday.\n\nHealth officials stress the importance of staying hydrated and cool during this heat wave. Residents should drink plenty of fluids, stay in air-conditioned spaces when possible, avoid prolonged sun exposure, and check on elderly relatives and neighbors who may be more vulnerable to heat-related illnesses.\n\nRelief is on the way. The Weather Service says showers and thunderstorms are expected to arrive Wednesday afternoon and evening, which should break this early season heat wave.\n\nStay with TV Delmarva for continued weather updates.","protected":false},"excerpt":{"rendered":"<p>A Heat Advisory is in effect for New Castle County through Wednesday evening, with heat index values reaching up to 98 degrees and
