The National Weather Service warned LeFlore County residents to brace for another possible riot of storms and flash flooding Thursday evening and today.
Storms overnight Tuesday dumped almost 5 inches of rain in parts of the county, broke and uprooted trees and washed out some roads.
A flash flood watch for most of eastern Oklahoma was in effect through tonight, according to the NWA Tulsa office.
A flash flood watch means rapidly rising water or flooding is possible and people in the area should be ready to act if they see flooding or a warning is issued.
The weather service said a large thunderstorm complex forming over the high plains was tracking southeast and could spawn damaging winds, hail and rain Thursday night, decreasing during the day and moving out of the area by tonight.
A clam, somewhat cooler weekend is forecast with a chance of storms returning early next week.
Despite the cooling effect the system was expected to bring into the area, heat indexes as high as 102 degrees were predicted in parts of southeastern Oklahoma Thursday, the NWS said.
