However... all interested parties should take necessary precautions
immediately.

Precautionary/preparedness actions...

Most flood deaths occur in automobiles. Never drive your vehicle into
areas where the water covers the roadway. Flood waters are usually
deeper than they appear. Just one foot of flowing water is powerful
enough to sweep vehicles off the Road. When encountering flooded
roads make the smart choice... turn around... dont drown.

Be especially cautious at night when it is harder to recognize the
dangers of flooding. If flooding is observed act quickly. Move up to
higher ground to escape flood waters. Do not stay in areas subject to
flooding when water begins rising.
