How Panola County floods

Flash flooding from severe storms and heavy rainfall dominates the flood risk profile in Panola County, accounting for 35 out of 39 recorded flood events over the last 30 years, alongside two tropical storms and two general floods. Recent events include a flash flood on May 30, 2024, driven by a convective system propagating from the southern High Plains, and repeated heavy rainfall from slow-moving thunderstorms on June 5, 2021. Additional flash flooding occurred on May 11, 2023, due to an upper-level low-pressure system funneling moisture into East Texas, and on May 5, 2022, associated with a surface low and stationary front.

National Flood Insurance Program records indicate historical payouts in areas outside standard mapped high-risk zones. Properties located in Zone X_UNSHADED recorded 5 claims with an average payout of $7,001 and an average recorded water depth of 2 inches. Properties in Zone UNKNOWN logged 2 claims with an average payout of $16,080 and an average recorded water depth of 3 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties outside designated high-risk zones, such as those in unshaded or unmapped areas, where localized heavy rainfall and flash flooding have historically caused property damage and generated insurance claims.

In flood insurance claims here that reported a flood depth, the average was 2 inches.

From the storm reports

Flash Flood · May 30, 2024. Remnants of a pre-dawn mesoscale convective system (MCS) that developed over the southern High Plains propagated downstream into the Ark-La-Tex region during the afternoon hours on May 30th. Diurnal heating and weak convective inhibition allowed for renewed development of severe thunderstorms along the leading edge of this long-lived MCS. Surface temperatures warmed into the 80s ahead of this convection across Eas…

Flash Flood · May 11, 2023. An upper level low pressure system slowly ejected northeast across the piney woods of East Texas during the evening through the morning hours of May 10th-11th. A southerly low level jet present ahead of the low spilled copious amounts of low level moisture north into East Texas and Western Louisiana, with strong large scale forcing ahead of the low enhancing numerous shower and thunderstorm development which moved…

Flash Flood · May 5, 2022. A surface low was centered over the southern Texas Panhandle with a stationary front extending through southern Oklahoma into southern Arkansas eastward into northern Mississippi. A dry line extended southward from the surface low through west Texas into the Big Bend Country along with a cold front draped southwest from the surface low into southeast New Mexico. Aloft, an upper-level low was initially centered jus…

Flash Flood · Jun 5, 2021. Scattered to numerous showers and isolated thunderstorms developed throughout the day on June 5th, ahead of a stationary cut off upper low pressure system over Central Texas. Daytime heating contributed to moderate instability within a very moist air mass in place. These showers and thunderstorms were very efficient rainfall producers as they moved slowly and often trained over the same areas over a given period…

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Panola County

If a building in Panola 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.
