Tips for flood weather

Officials offered the following tips for residents to prepare for approaching storms and potential flooding threats.

• Protect your property from floodwaters and purchase flood insurance.
• Plan for sheltering where you are and for evacuation.
• Evacuate if advised.
• Seek high ground (for flash floods) or stay on high ground.
• Avoid walking or driving in floodwaters. Depth and velocity of the water are not always obvious; the ground or road may suddenly wash away and hidden dangers may exist; do not attempt to evacuate through floodwaters.

• Seek professional review or inspection of structures and utilities before entering buildings that are flooded.
