In the second day of the Border Fire, authorities issued additional evacuations across Southern Californian communities between Campo and Potrero as triple-digit heat fueled the blaze, growing from 1,900 acres to 7,500 acres, nearly 12 square miles.
Crews worked throughout the day during record-breaking heat to battle the Border Fire, which ignited Sunday and quickly grew Monday from 1,900 acres to 7,500 acres in a matter of hours. Cal Fire officials said the wildland fire was 5 percent contained.

"As we came out of Potrero, there was fire on both sides of the road, so I guess it was a good thing we got out when we did," evacuee Andy Lindsay said at the evacuation location on Sheridan.
Lindsay spent six days in an evacuation center during the Harris Fire in 2007. In 2007, the Harris Fire burned more than 90,000 acres in the same area, killing one person and badly burning another. The fire also destroyed 253 homes.
"Hopefully we won't be here for five or six days like we were last time," he said.
Sunday night the California Governor’s Office of Emergency Services secured a Fire Management Assistance Grant from the Federal Emergency Management Agency to help ensure the availability of vital resources to suppress the fire.
The FMAG also enables local, state and tribal agencies to recover eligible costs.
Record-breaking heat across San Diego County was expected to continue Monday as a heat wave passed through Southern California. NBC 7 Meteorologist Jodi Kodesh forecasted valleys in the low 100s, mountains in the upper 90s and deserts with highs at 119.
The National Weather Service said an excessive heat watch will be in effect for parts of San Diego County and Imperial County, including valleys, mountains and deserts, from Sunday morning through next Thursday evening.
Communities that will feel the heat the most include: El Cajon, Santee, La Mesa, Poway, Pine Valley, Julian, Escondido, San Marcos, Lake Arrowhead and Big Bear.
