Heat advisory issued for SLO County. How long will triple-digit temperatures last?
Triple-digit temperatures are set to scorch parts of San Luis Obispo County this week, according to the latest forecast from the National Weather Service.
High heat is expected throughout the week, said Bryan Lewis, a meteorologist for the National Weather Service.
“There’s a little bit of uncertainty” about when temperatures will start to drop, he said, but it is not unusual to see triple-digit temperatures during this time of the year.
An upper-level, high-pressure system centered over North Central California is limiting off coastal winds that typically act as a natural air conditioner for San Luis Obispo County, Lewis said.
The weather service warned that temperatures up to 105 are expected.
