The National Weather Service has put an Extreme Heat Warning into place for New Castle County and the surrounding region, covering a stretch that runs from this Wednesday through the Fourth of July holiday.
The warning took effect at noon on Wednesday, July 1, 2026, and is set to remain active until 8:00 PM on Saturday, July 4, 2026. That means dangerous heat conditions are expected to grip the area for the entire holiday weekend.
Forecasters are warning that heat index values — which reflect how hot it actually feels when humidity is factored in — are anticipated to climb to hazardous levels during this period. Residents are urged to take the warning seriously and take steps to stay safe in the extreme heat.
Officials recommend staying indoors during the hottest parts of the day, drinking plenty of water, and checking on elderly neighbors, young children, and pets. Cooling centers may be available in the area for those without access to air conditioning.
