Wildfiretoday.com  Map showing heat detected by a satellite over the Border fire at 1:20 p.m. PDT June 20, 2016 (the red icons). The brown icons represent heat detected at 2 a.m. June 30. It is likely that in areas with light fuel, such as grass, the fire burned and then cooled before the satellite overflight and was not detected in those areas. Therefore, the fire may be larger than indicated by the satellite data.

The map above shows Monday’s eastward movement of the Border Fire at 1:20 p.m. It became well established on the north side of Highway 94.

At 3 p.m. CAL FIRE reported the fire had burned 1,900 acres, and “triple digit temperatures and single digit humidity are creating extreme fire behavior and increased activity is being experienced”.

Evacuations are still in effect.

Live video from the Fox TV station in San Diego at 7 a.m. PDT Monday showed very little activity on the Border Fire near Potrero, California just north of the Mexico border. It was generating smoke but much of it was hanging in the valleys or drifting off to the west. There were a few areas with active flame.

Highway 94 is closed and the evacuation order for Potrero remains in effect. The evacuation shelter is at the Campo Elementary School, 1654 Buckman Springs Road.

At 7:30 a.m. PDT CAL FIRE reported the fire had burned 1,900 acres and destroyed four outbuildings. There have been three firefighter injuries that required transport to medical facilities. They expect to have a very significant number of aircraft supporting firefighters today. An incident management team has been ordered.

Border fire mapThe Border Fire started in triple-digit temperatures at 11 a.m. today and by 7:15 PDT had grown to 1,500 acres (according to CAL FIRE) and forced the complete evacuation of Potrero, 18 air miles southeast of the San Diego metropolitan area. It is burning near the Mexico border north of Tecate, Mexico close to the intersection of Highways 94 and 188, requiring the closure of Highway 94.

Numerous structures are threatened and some cellular phone service has been knocked out by the fire.

The high temperature at Potrero today was 104 degrees with 9 percent relative humidity. It will be even hotter on Monday with a forecast for the fire area of 111 degrees, 8 percent relative humidity, and winds out of the north and northwest at 13 to 18 mph. These predicted weather conditions will present a challenge for firefighters having to work in that environment, but the weather will also be conducive to additional fire growth.
