Local Flooding
Flooding can occur after prolonged rainfall over several days causing a river or stream to overflow and flood the surrounding area. Flash flooding can occur after intense rainfall of one inch or more an hour. Flash floods often give very little warning, developing in a few minutes or a few hours. A flash flood watch means flooding or flash flooding is possible in your area. Stay tuned to local television and radio for updates or advice. For the late evening and early morning hours, it is recommended that you purchase a NOAA weather radio, which automatically announces impending dangerous weather situations.
It is important for residents and business owners in flood prone areas to monitor local television and radio for flood updates in order to have time to take protective measures with their property. The city does not notify individual property owners during minor flooding events. For things you can do to protect your property during flooding click here.
