San Francisco Frontiers - Battle rages against Chile forest fires one week in

More than 5,600 local firefighters, with backup from personnel flown in from Mexico, Colombia and Spain, were actively battling 89 priority fires out of a total of 311 burning a week into the disaster, officials said.

"We are entering the most complex part of the week," Interior Minister Carolina Toha said Wednesday.

"We have an alert for high temperatures for today, tomorrow and the next day in several regions of the country, requiring the mobilisation of a very large effort... to prevent the fires from spreading," she told reporters.

Fires have razed more than 309,000 hectares (763,000 acres) in the Maule, Nuble, Biobio and La Araucania regions, officials say -- an area equivalent to one third of Puerto Rico.

The official death toll was adjusted downward Wednesday by two to 24, with the number of people injured by the fires reaching 2,180.

A total of 1,180 homes have been destroyed, leaving more than 5,500 people homeless.

"If the temperature rises and the wind increases, we may indeed have more problems, and we already have many fires," Lieutenant Colonel Carlos Javier Martin Traverso, head of a Spanish military contingent providing help in Chile, told AFP.

He expressed concern about the so-called "triple 30" factor -- humidity under 30 percent, temperatures over 30 degrees Celsius (86 Fahrenheit) and winds above 30 kilometers (18.6 miles) per hour -- which, if present, could make for a fire of "great magnitude, virulence and potency."

Chile is in the grips of a 13-year drought.
