Bob Spieldenner with the Virginia Department of Emergency Management says if you know your house is flood prone, take action now.
Keep exterior basement drains free from debris and protect anything on lower levels that could be damaged from water. Elevate big items like furnaces and hot water heaters. If they get water inside, they won't work and can be expensive to replace. You should also tie down grills and outdoor furniture to avoid it blowing away and causing damage to your home.
Sometimes weather watches and warnings come in time, but not always.
