Florida Gov. Charlie Crist declared a state of emergency Monday as wildfires fed by drought conditions threatened homes and businesses and forced the closing of part of Interstate 95. The fire situation has been very unpredictable and the winds have basically caused what fires that developed in the state on Sunday. Governor Charlie Crist activated the National Guard to help battle the blazes and help with evacuations. Dense smoke forced the closure of several roads, including I-95 for a seven-mile stretch in Brevard County near Malabar. The interstate was also closed for a short time Monday morning near Cocoa. Some of the fires were likely set by arsonists.
