(Smyrna, DE) – This afternoon, the National Weather Service has upgraded the heat advisory to an “Extreme Heat Warning” for all three counties, starting today, July 1st, through July 4th. The hottest weather is expected on Thursday and Friday.
An Extreme Heat Warning is issued when dangerous heat is occurring or imminent. This advisory should be taken seriously, and preparations should be made now.
The State of Delaware is closely monitoring the weather as we approach the Fourth of July weekend and is working with our local county partners to ensure our communities are prepared. As such, the Delaware Emergency Management Agency and the Department of Health and Social Services are sharing important information on how individuals can best prepare and assist the most vulnerable.
Heat Safety
- Monitor the weather projections from the National Weather Service and local news agencies.
- Practice Heat Safety measures including:
- Staying hydrated, avoiding alcohol, and considering beverages with electrolytes.
- Take breaks in the shade as often as possible
- Check on the elderly and those without air conditioning.
- Limit strenuous outdoor activities.
- Understand the signs of heat exhaustion and heat stroke.
- Use sunscreen (SPF 30 or higher) every two hours.
- Wear lightweight, loose-fitting, and light-colored clothing.
Those at the highest risk:
- Young children and infants are particularly vulnerable to heat-related illnesses and death, as their bodies are less able to adapt to heat than adults.
- Older adults, particularly those who have pre-existing medical conditions, take certain medications, are living alone, or have limited mobility, may experience multiple heat-related health impacts.
- People with chronic medical conditions are more likely to have a serious health problem during a heat wave than healthy people.
- Pregnant women are also at higher risk. Extreme heat events have been associated with adverse birth outcomes such as low birth weight, preterm birth, and infant mortality.
Knowing the Signs of Heat Exhaustion and Heat Stroke
Heat Exhaustion:
- Dizziness
- Extreme thirst
- Heavy sweating
- Nausea
- Weakness
Heat exhaustion can quickly lead to heat stroke. It is recommended to act fast by moving to a cooler area, loosening tight clothing, sipping cool water, and seeking medical help if symptoms do not improve.
Heat Stroke:
- Confusion
- Dizziness
- Loss of Consciousness
Heat stroke can cause death or permanent disability if emergency treatment is not given. Call 911, move the person to a cooler area, loosen tight clothing, and slowly cool with water and ice.

Animal Heat-Related Safety
Essential Heat Precautions
- Provide shade and water — Pets should have access to cool, shaded areas and fresh water at all times. The safest place during excessive heat is indoors.
- Follow excessive heat warnings — Dogs may not be left outdoors during a National Weather Service excessive heat warning.
- Avoid leaving pets unattended outside — Overheating, entanglement, or injury can happen quickly when no one is present.
- Never leave pets in vehicles — Even mild temperatures can become dangerous. A car can reach nearly 90°F in 10 minutes when it’s only 70°F outside. Call Delaware Animal Services at 302-255-4646 or 911 if you see an unattended pet in a hot vehicle.
Walking Dogs Safely
- Choose cooler times of day — Early morning or late evening walks reduce heat exposure.
- Check pavement temperature — If the surface is too hot for your hand, it’s too hot for paws.
Signs of Heat Stroke
- Watch for symptoms — Excessive panting, drooling, weakness, collapse, or unsteadiness can indicate heat stroke. Severe cases may include seizures or bloody diarrhea.
- Seek immediate veterinary care — Heat stroke is life-threatening and requires urgent attention.
Special Considerations
- Flat faced breeds — Dogs like Pugs and Bulldogs overheat more easily and should remain in air-conditioned spaces during warm weather.
