 We're expecting widespread rainfall totals across portions of the Texas Gulf Coast, much of eastern Texas of 5 to 10 inches. We don't know exactly where that heaviest rainfall is going to fall. It will depend on the details of barrels tracked, but the potential is there for some isolated totals to exceed 15 inches in some locations, and that's going to lead to the potential for some fairly significant flash flooding, especially as we get into the day on Monday.
