Sonoma County Health Officer extends Heat Advisory

En español » 

In response to the National Weather Service’s extension of the Excessive Heat Warning for much of the county, Sonoma County Health Officer Dr. Tanya Phares has extended the countywide Heat Advisory that began Tuesday, July 2 to Tuesday, July 9. The Advisory had been expected to end today. 

The heat alert applies to inland areas of Sonoma County where high temperatures are forecast to be in the mid-high 90s and low 100s, depending on location. Santa Rosa is forecast to remain in the 90s all of next week. 

Such weather conditions can cause heat stroke and worsen chronic medical conditions, leading to severe complications and death. Dr. Phares urges residents to take simple steps to stay cool and help prevent heat-related illnesses.

“Extreme heat is very taxing on the body and significantly increases the potential for heat-related illnesses, especially for those working outdoors or participating in outdoor activities,” said Dr. Phares. “There are many things we can do to reduce heat-related problems and stay safe during hot summer days.” To protect yourself, your family and pets when the weather is very hot, follow the tips below:

• Never leave anyone, including children or pets, in a parked car, even briefly. Temperatures in the car can become dangerous within a few minutes.
• Use air-conditioning to cool down or go to an air-conditioned building, such as a mall or movie theater, or go to one of a number of cooling centers available throughout Sonoma County. (For an updated list of cooling centers and hours of operation, go to to SoCoEmergency.org).
• Drink plenty of fluids. Don't wait until you're thirsty to drink more fluids. Avoid alcohol, caffeine and sugary drinks. If your doctor generally limits the amount of fluid you drink or has you on water pills, ask how much you should drink while the weather is hot.
• Beat the heat with cool showers and baths.
• Stay out of the sun as much as possible.
• When possible, avoid strenuous activity during the hottest part of the day (between 11 a.m. and 5 p.m.) and take regular breaks from physical activity.
• Wear loose, lightweight, light-colored clothing to help keep cool.
• Wear sunscreen and a ventilated hat (e.g., straw or mesh) when in the sun, even if it is cloudy.
• Be aware that some medicines affect the body's ability to sweat and stay cool, including antihistamines, antidepressants, over-the-counter sleeping pills, anti-diarrhea pills, beta blockers and psychiatric drugs. Do NOT stop taking medication unless instructed to do so by your doctor.
• Check on your neighbors, especially the elderly or those in poor health to see if they need assistance.
• Don’t walk your dogs in the heat. Pavement temperatures can be 40 to 60 degrees hotter than air temperatures. Always check the pavement to see if it is cool enough for them to walk on.

Signs and symptoms of heat stroke include the following:

• High body temperature (103° F or higher)
• Hot, red, dry or damp skin
• Fast, strong pulse
• Headache
• Dizziness
• Nausea
• Confusion
• Losing consciousness (passing out)

 If someone near you experiences these symptoms, do the following:

• Call 911 right away- A heat stroke is a medical emergency
• Move the person to a cooler place
• Help lower the person's temperature with cool clothes or a cool bath
• Do not give the person anything to drink
