AccuWeather has the details you need to know about heat stroke, a serious health condition, and heat exhaustion, which can precede it.

"In fact, the only place in the Bay Area immune to moderate-to-high heat illness risk is the coast," said Nicco.

The Centers for Disease Control and Prevention says "those at greatest risk for heat-related illness include infants and children up to four years of age, people 65 years of age and older, people who are overweight, and people who are ill or on certain medications."

"We have a touch of humidity out there, which makes it even more dangerous because it's harder for your body to cool down," said Nicco. "That humidity is going to start to sliding away, later on tonight and tomorrow (Saturday), but the heat will remain and as long as that humidity is around we have a slight chance of an isolated thunderstorm. The best chance is going to be over the ocean."

"Heat warnings will likely be extended through next week, as the heat will hang around for the next seven days," said Nicco.
