February 11, 2016Online interactive journal outlines 2015 South Carolina historic rain and flooding
The historic heavy rainfall event of Oct. 1-5, 2015 produced record rainfall rates and totals in South Carolina. Finding information about that event is now easier due to a new online interactive journal from the S.C. Department of Natural Resources (DNR) State Climatology Office. The S.C. State Climate Office hopes the site will help everyone better understand the State's vulnerability to flood so that we can work together to be more aware and resilient.

Important Flood Safety Information
- Over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water.
- Second highest percentage of flood-related deaths is due to walking into or near flood waters.
- People underestimate the force and power of water. 6 inches of fast-moving flood water can knock over an adult. It takes just 2 feet of rushing water to carry away most vehicles. It is NEVER safe to drive or walk into flood waters.
- Homeowners' insurance does not cover flood damage.
- South Carolina has 199,300 National Flood Insurance Program policies which ranks 6th in the nation. If you live in a Special Flood Hazard Area or high-risk area and have a Federally- backed mortgage, your mortgage lender requires you to have flood insurance.
- Anyone can be vulnerable to flooding. Even if you live in a low-risk area you can purchase flood insurance so long as your community participates in the National Flood Insurance Program (NFIP). People outside of the high-risk flood areas file 20-percent of all NFIP claims.
