How Phillips County floods

Flash flooding and river flooding drive the flood risk profile in Phillips County, shaped by 12 flash flood events, 6 general flood events, and 1 tropical storm over the last 30 years. Heavy rain events can occur throughout the year, such as multiple rounds of rain that flooded roads across the county in December 2020, and heavy rainfall from an upper-level low system that caused flash flooding in East-Central Arkansas on June 9, 2021.

National Flood Insurance Program records indicate claims across multiple zones, with the highest volume concentrated in Zone A at 284 claims averaging a 2-inch recorded water depth and $9,333 in payouts. Unshaded Zone X accounts for 74 claims with an average 2-inch water depth and $6,909 payouts, while Zone X claims average a 3-inch water depth with $34,046 payouts across 31 claims.

Homeowners and real estate agents working in Zone A and unshaded Zone X should pay the closest attention to property risk, as these areas account for the vast majority of historical flood insurance claims in the county.

From the storm reports

Flash Flood · Apr 5, 2025. The front eventually sagged south back into the Mid-South during the early morning hours of April 5th. Strong low-level moisture transport into the frontal zone resulted in heavy rain and training storms across northern sections of the Mid-South, mainly north of I-40. A bow echo developed along and just south of the slowly advancing front. This feature crossed the entire forecast area producing 13 tornadoes, inclu…

Flash Flood · Jun 9, 2021. An upper low continued to meander across the region on June 9, 2021. Weak upper-level disturbances rotated around the upper low and interacted with a very moist air mass across the Mid-South to produce several rounds of heavy rain across East-Central Arkansas and North Mississippi. There were several instances of flash flooding.

Flood · Dec 31, 2020. Several rounds of rain moved across east-central Arkansas late in 2020. A few roads were flooded across Phillips County.

Flash Flood · Jun 23, 2020. A cold front sagged into the Mid-South and stalled across east-central Arkansas into northwest Mississippi. A strongly unstable airmass combined with enough wind shear to produce numerous thunderstorms. One became severe and produced damaging winds in Helena - West Helena along with some flash flooding.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Phillips County

If a building in Phillips 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.
