Flooding is a threat nearly every day of the year. The rain this week reminds Long Islanders that we need to always be prepared for the possibility of flooding. Below is information from the Disaster Information Management Research Center on being prepared. Sometimes floods develop slowly and forecasters can anticipate where a flood will happen days or weeks before it occurs. Oftentimes flash floods can occur within minutes and sometimes without any sign of rain. Being prepared can save your life and give you peace of mind.
