Delaware<\/strong> is bracing for oppressive heat<\/strong> this Friday, July 25<\/strong>, with an extreme heat warning<\/strong> in effect for New Castle County<\/strong>, and a heat advisory<\/strong> issued for Kent<\/strong> and Sussex counties<\/strong>. The warnings are active from 10 a.m. to 9 p.m.<\/strong>, as humid and dangerously hot air<\/strong> moves into the region.<\/p>\n <\/p>\n According to the National Weather Service in Mount Holly, New Jersey<\/strong>, heat index values<\/strong>\u2014which represent how hot it feels<\/em> when humidity is factored in\u2014will climb between 100 and 106\u00b0F (37.7 to 41.1\u00b0C)<\/strong> across Delaware<\/strong>, New Jersey<\/strong>, southeastern Pennsylvania<\/strong>, and northeastern Maryland<\/strong>.<\/p>\n <\/p>\n In Delaware<\/strong>, here’s what Friday\u2019s heat index<\/strong> could feel like:<\/p>\n Wilmington<\/strong>: 105\u00b0F (40.5\u00b0C)<\/strong> <\/p>\n Health risks<\/strong> increase sharply with these kinds of conditions. Exposure to this level of heat and humidity<\/strong> can lead to heat-related illnesses<\/strong>, especially among vulnerable populations like children, older adults, and those with chronic health issues.<\/p>\n Adding to the dangerous conditions, there\u2019s a chance for severe thunderstorms<\/strong> to develop Friday afternoon and evening<\/strong>. While the entire state of Delaware<\/strong> could see storms, the most significant threat<\/strong> is expected north of Georgetown<\/strong>, particularly across New Jersey<\/strong> and eastern Pennsylvania<\/strong>.<\/p>\n <\/p>\n The primary concern will be locally damaging wind gusts<\/strong>, though large hail<\/strong> and heavy rain bursts<\/strong> are also possible.<\/p>\n Looking ahead to the weekend<\/strong>, humid conditions<\/strong> will persist, although temperatures won\u2019t be quite as extreme. Still, the risk of strong storms<\/strong> continues, especially on Saturday, July 27<\/strong>, when heavy downpours<\/strong> could trigger flash flooding<\/strong> in parts of the region.<\/p>\n <\/p>\n The National Weather Service<\/strong> warns that although the heat wave<\/strong> may ease slightly over the weekend, the humidity<\/strong> will still be uncomfortably high, especially during the daytime hours.<\/p>\n A heat advisory<\/strong> is triggered when heat index values<\/strong> are expected to exceed 100\u00b0F (37.7\u00b0C)<\/strong> during the day, and nighttime temperatures stay above 75\u00b0F (23.8\u00b0C)<\/strong>. An excessive heat warning<\/strong>, on the other hand, is issued when extreme heat<\/strong> is imminent or already occurring.<\/p>\n When the heat index<\/strong> climbs:<\/p>\n <\/p>\n These conditions limit the body’s ability to cool itself. High humidity levels<\/strong> reduce the rate of evaporation<\/strong> from sweating, making it harder to regulate body temperature<\/strong>.<\/p>\n Stay alert as Friday\u2019s heat<\/strong> builds and afternoon storms<\/strong> become more likely, particularly in northern Delaware<\/strong> and nearby states.<\/p>\n","protected":false},"excerpt":{"rendered":" Delaware is bracing for oppressive heat this Friday, July 25, with an extreme heat warning in effect for New Castle County, and a heat advisory issued for Kent and Sussex counties.
