How Warren County floods

Flash flooding from heavy rain events dominates the flood risk profile in Warren County, North Carolina. Over the last 30 years, the NOAA Storm Events Database recorded 25 flash flood events resulting in 3 deaths, alongside 5 hurricane events and 2 tropical storm events.

Recent historical events illustrate this hazard. In September 2021, a cluster of slow-moving showers and storms produced heavy rain and multiple reports of flash flooding across the county. In November 2020, moisture from Tropical Storm Eta combined with a slow-moving cold front to produce widespread rainfall totals generally ranging from 4 to 6 inches, with localized totals near Rocky Mount approaching 10 inches. Additionally, the passage of Hurricane Isaias in August 2020 brought 2 to 5 inches of rain and gusty winds up to 50 to 60 miles per hour, resulting in flash flooding and minor river flooding.

Historical National Flood Insurance Program records show limited claims activity, consisting of 3 claims in Zone A with an average payout of $0 and an average recorded water depth of 0 inches, and 1 claim in Zone X with an average payout of $0 and an average recorded water depth of 0 inches. Property owners and real estate professionals should pay the closest attention to properties located within designated Zone A flood hazard areas.

Flash Flood · Sep 8, 2021. A cluster of showers and storms producing heavy rain develop across Warren County in central North Carolina along a slow moving mid level disturbance in advance of a slow moving cold front. The heavy rain produced a couple of reports fo flash flooding across Warren County.

Flash Flood · Aug 31, 2020. Warm moist air lifted along a wavy stationary front. This combined with slow moving and merging thunderstorms resulted in heavy rain and flash flooding, including a dam break in Johnston County and two fatalities.

Flash Flood · Nov 12, 2020. Moisture from Tropical Storm Eta was drawn northward into the Mid Atlantic during the day of Wednesday November 11th. Meanwhile, a slow moving cold front approached the area and made its way through central North Carolina during the day Thursday, resulting in widespread showers and isolated thunderstorms. Rainfall totals were generally in the 4 to 6 inches range, although some spots near Rocky Mount saw close to 1…

Significant rain fell across the Coastal Plain, Sandhills and eastern Piedmont of North Carolina as Isaias moved northward through the state along with gusty winds up to 50 to 60 miles per hour.

Flood insurance in Warren County

If a building in Warren County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
