TULSA, Okla. (AP) — Forecasters say dry and windy weather will keep Oklahoma vulnerable to wildfires over the next couple of days. The National Weather Service says strong gusts will make it easy for any fires that start Tuesday and Wednesday to spread. Forecasters say that by Thursday, significant rain chances should dampen the threat somewhat. On Monday, a number of fires spread in northeast Oklahoma. One fire burned in Okmulgee, Creek County and northern Tulsa Counties. Copyright 2012 The Associated Press.
