Bay Area to endure 2-week warm spell as temperatures run 10 to 20 degrees above average
SAN FRANCISCO (KGO) -- Temperatures are expected to climb significantly this weekend across the Bay Area, bringing a major heat risk to inland areas.
ABC7 Eyewitness News meteorologist Drew Tuma says high temperatures will run 10 to 20 degrees above average, with some locations potentially reaching record highs. A heat advisory has been extended through Wednesday, with forecast highs ranging from 90 to 103 degrees.
The expected heat poses a significant health concern. Heat is the leading weather-related cause of death, exceeding fatalities linked to thunderstorms, flooding and tornadoes.
The prolonged stretch of hot weather is also expected to continue beyond the weekend. Tuma says the warm spell will persist for the next two weeks.
Residents are urged to prepare for extended periods of hot weather as temperatures remain well above seasonal norms through the first half of October.
Spare the Air Alerts issued for weekend
The Bay Area Air District has issued Spare the Air alerts for Saturday and Sunday because of a forecast of hot weather and light winds that is expected to lead to elevated pollution levels. But on Sunday, it was extended through Monday, Oct. 5.

The National Weather Service has issued a Heat Advisory for 11 a.m. Saturday through 10 p.m. Wednesday for most of the Bay Area besides some places along the coast and in the North Bay because of expected triple-digit inland temperatures.
The air district said the weather conditions are expected to produce elevated concentrations of ozone, otherwise known as smog.
On Spare the Air days, outdoor exercise is advised only in the early morning hours when smog levels are lower. The pollution is particularly harmful for young children, older adults, and people with respiratory and heart conditions, according to the air district.
