Heat advisory in New Castle County through Wednesday evening<\/strong><\/p>\n NEW CASTLE County<\/strong>, in Delaware<\/strong>, is currently under a heat advisory<\/strong> effective from 11:00 a.m. on Tuesday, June 18<\/strong> through 8:00 p.m. on Wednesday, June 19<\/strong>. After a gloomy and unseasonably cool Father’s Day<\/strong>, where highs barely reached 65\u00b0F (18\u00b0C)<\/strong>, residents are now facing a sharp rise in heat and humidity<\/strong>.<\/p>\n The heat index<\/strong> is expected to climb to around 99\u00b0F (37\u00b0C)<\/strong> due to high temperatures<\/strong> near 86\u00b0F (30\u00b0C)<\/strong> and elevated humidity levels<\/strong>, increasing the risk of heat-related illnesses<\/strong>.<\/p>\n <\/p>\n What to expect across Delaware<\/strong><\/p>\n New Castle County<\/strong>: Temperatures on June 18<\/strong> will peak around 86\u00b0F (30\u00b0C)<\/strong> with an 80% chance of showers and thunderstorms<\/strong> during the afternoon. By Wednesday, June 19<\/strong>, highs could reach 91\u00b0F (33\u00b0C)<\/strong> with another 80% chance of storms<\/strong>, especially after 2:00 p.m.<\/strong>, some of which may become severe<\/strong>. The skies are expected to clear by the weekend<\/strong>, with sunshine<\/strong> and highs in the low 80s\u00b0F (27\u201328\u00b0C)<\/strong> on Thursday, June 20<\/strong>, the high 80s\u00b0F (31\u00b0C)<\/strong> on Friday, June 21<\/strong>, and the low 90s\u00b0F (32\u201333\u00b0C)<\/strong> by Saturday, June 22<\/strong>.<\/p>\n Kent County<\/strong>: No official heat advisory<\/strong> is in place, but the region will still experience highs in the low 90s\u00b0F (32\u201333\u00b0C)<\/strong> on June 18<\/strong>, followed by afternoon thunderstorms<\/strong>. On June 19<\/strong>, highs will stay around 93\u00b0F (34\u00b0C)<\/strong>, again with the potential for showers and storms<\/strong>. Like New Castle, sunny and hot weather<\/strong> will dominate the weekend.<\/p>\n Sussex County<\/strong>: Similarly, Sussex<\/strong> is not under a heat alert<\/strong>, but temperatures will soar into the 90s\u00b0F (32\u201334\u00b0C)<\/strong> on Tuesday<\/strong>, with storms possible in the afternoon<\/strong>. The June 19<\/strong> forecast mirrors that of Kent<\/strong>, with highs near 93\u00b0F (34\u00b0C)<\/strong> and another round of showers and thunderstorms<\/strong>. Expect sunshine and rising temperatures<\/strong> from Thursday through Saturday<\/strong>, with mid-80s\u00b0F (29\u00b0C)<\/strong> on June 20<\/strong>, upper 80s\u00b0F (31\u00b0C)<\/strong> on June 21<\/strong>, and low 90s\u00b0F (32\u201333\u00b0C)<\/strong> on June 22<\/strong>.<\/p>\n <\/p>\n Understanding heat advisories and heat index<\/strong><\/p>\n A heat advisory<\/strong> is typically issued within 12 hours<\/strong> of the onset of dangerously hot conditions<\/strong>, usually when the heat index<\/strong> surpasses 100\u00b0F (38\u00b0C)<\/strong> and nighttime temperatures remain above 75\u00b0F (24\u00b0C)<\/strong>. While the specific criteria can vary by region<\/strong>, the general guidance is based on the risk of heat exhaustion or heat stroke<\/strong>.<\/p>\n The heat index<\/strong> reflects how hot it feels<\/strong> to the human body<\/strong> when relative humidity<\/strong> is added to the air temperature<\/strong>. On humid days<\/strong>, sweat evaporates more slowly, limiting the body\u2019s ability to cool itself. This makes the air feel significantly hotter<\/strong> than the actual temperature.<\/p>\n <\/p>\n The National Weather Service<\/strong> classifies heat index readings as follows:<\/p>\n Caution<\/strong> (80\u201390\u00b0F \/ 27\u201332\u00b0C): Fatigue<\/strong> possible with extended activity or exposure. Conditions across Delaware<\/strong> will continue to be oppressive<\/strong> through midweek<\/strong>, with daytime highs<\/strong> and humidity<\/strong> making it critical to understand how the heat index<\/strong> affects the body.<\/p>\n","protected":false},"excerpt":{"rendered":" Heat advisory in New Castle County through Wednesday evening NEW CASTLE County, in Delaware, is currently under a heat advisory effective from 11:00 a.m. on Tuesday, June 18 through 8:00 p.m. on Wednesday, June 19.
