Precautionary/preparedness actions... A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Vehicles caught in rising water should be abandoned quickly. If your vehicle stalls...abandon it and seek higher ground immediately. Rapidly rising water may engulf your vehicle and its occupants and sweep them away. Move to higher ground.
