MIAMI (AP) - Floridians, brace yourselves for a chilly couple of days.

An arctic front has made its way to the state, threatening subfreezing temperatures Monday night. The frigid weather is expected to linger until at least midweek.

Gov. Charlie Crist has declared a state of emergency to relax restrictions in getting harvested crops moved to processing centers before the cold kills them.

State officials are urging residents to use safe heating sources and bring pets inside. And the Florida Highway Patrol warns that it's illegal to leave a car running - even if it does keep the inside toasty while you make a quick stop.
