Instructions in this archived message

Move to higher ground now. Act quickly to protect your life. Stay away or be swept away. River banks and culverts can become unstable and unsafe. Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks.
