How Pemiscot County floods

River overflow along the Mississippi and flash flooding dominate the flood history of Pemiscot County, supported by NOAA records showing 13 flash flood events, 3 flood events, and 1 tropical storm over the last 30 years. Heavy rainfall, slow-moving storm systems, and spring snowmelt drive these hazards. For example, a slow-moving storm system caused extensive areal and river flooding on February 11–12, 2019, while a combination of heavy rain and northern snowmelt produced record-breaking flooding on the Mississippi River in May 2011 that closed roads and flooded homes and businesses.

NFIP claims data demonstrates that properties situated in FEMA Zone A have experienced the highest concentration of vulnerability, recording 101 claims with an average payout of $10,409 and an average recorded water depth of 3 inches. Properties in Zone X recorded an average payout of $10,584 with an average recorded water depth of 2 inches, while shaded Zone X properties recorded an average payout of $8,451 with an average water depth of 8 inches. Homeowners and real estate agents with properties in Zone A and river-adjacent areas should pay the most attention to flood risk, along with properties in shaded Zone X areas where average recorded water depths during past claims reached 8 inches.

From the storm reports

Flood · Feb 11, 2019. A slow moving storm system in the Lower Mississippi Valley produced heavy rain that caused flash flooding, extensive areal and river flooding of adjacent areas over portions of Bootheel of Missouri on February 11th and 12th.

Flood · Feb 21, 2015. Melting snow and sleet from recent winter storms combined with heavy rain to produce isolated flooding of low lying areas across parts of the Missouri Bootheel on February 21, 2015. A few roads were closed.

Flash Flood · Mar 8, 2012. A slow moving cold front pushed across the Missouri Bootheel during the afternoon of March 8, 2012. Showers and a few thunderstorms developed along and behind the front dumping a couple inches of rain across the area. Isolated flash flooding occurred as a result of the heavy rain.

Flash Flood · Feb 24, 2011. A warm front pushed north from the gulf coast and stalled across northern sections of the Mid-South during the early morning hours on February 24th. Widespread showers and thunderstorms developed along the stalled front producing very heavy rain and flash flooding. Late that afternoon and evening a cold front pushed across the Mid-South. An intense squall line developed in advance of the front with widespread dama…

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.

Flood insurance in Pemiscot County

If a building in Pemiscot 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.
