Multiple records were shattered Tuesday and San Diego County residents kept an eye on the skies as a fire weather warning continued into the second day.
The National Weather Service issued a fire weather warning until 6 p.m. Wednesday meaning any fires that develop will likely spread rapidly especially through Tuesday.
In Vista, temperatures up to 107 degrees were recorded Tuesday, according to the National Weather Service. That tops 96 degrees recorded in 1965. The average this time of year for Vista is 76 degrees.
Poway also saw temperatures in the 107-108 range, according to the NWS.
With record-breaking temperatures and near-zero humidity, the conditions were ripe for a fast-spreading fire and local fire agencies have staffed up in advance.
The U.S. Forest Service increased the threat index for Santa Ana-driven wildfires. On Monday, the agency said any fires that erupted "may grow rapidly." On Tuesday, the Forest Service said that "upon ignition, fires will grow rapidly and will be difficult to control."
Fire crews in the county were also prepared, in case of any wildfires.
"When the weather gets hot and dry, we have to be prepared," said John Buchanan with the North County Fire Protection District.
Excessive heat warnings were in effect for inland communities like Escondido, El Cajon, San Marcos, La Mesa, Santee, and Poway. Vista, Carlsbad, Encinitas, Chula Vista, National City, and San Diego were also under an excessive heat warning, according to the NWS.
In Campo, winds were blowing at 45 mph, forcing truck drivers to pull over for safety reasons. Signs posted along Interstate 8 also warned motorists of High Wind Danger.
Eighty-five schools will be on a minimum day schedule Tuesday and Wednesday due to expected excessive heat, the San Diego Unified School District officials said.
