Bring outdoor possessions inside. Move valuables and essential items to upper floors. Sandbags should be stacked well away from the building to avoid damaging walls. If major flooding is expected, flood the basement with clean water to equalize the water pressure on the outside of basement walls and floors. Round up pets.
Evacuation Use travel routes recommended by local authorities.
Keep a radio on for news and updates. Watch for flooding at bridges, viaducts, and low areas. Be alert for thunder and lightning that may signify rain and more flooding ahead. Don't drive over flooded roads. It's impossible to tell how deep the water is, or if portions of the roadway have been washed out.
