EL CENTRO - Imperial County Fire Department suspects the nine haystack fires in as many days are connected.
"Anytime you have a large amount of fire with the same consistency like the ones we have here,” Imperial County Deputy Fire Chief Salvador Flores said, “where a haystack burns in the evening usually around 10:30 to about midnight in this area, that's a pattern."
Extinguishing haystack fires is very difficult fire officials said. It's a large fuel load. Usually they are separated from any other flammable material, but sometimes they are close to other stacks or fields.
“The amount of radiant heat can actually start another fire," said Flores.
The Imperial County Fire Department is working with local authorities and asking for help from the community.
"We're working closely with Imperial County Sheriff's Department. We're still in the investigation phase. There are some leads that are coming in and we ask the public that if they know anything to please give us a call. And of course, if they see any suspicious activity to call 9-1-1 immediately," Flores said.
Imperial County Sheriff's Office said they're increasing patrol in the area of fire activity.
