Motley County, Texas Flood Zone Map

2 federal flood & hurricane disasters

FEMA’s digital flood map shows no high- or moderate-risk zones in Motley County. That can mean the area was never studied in detail or has no digital map, not that it can’t flood; the county floodplain administrator can say which.

Share of the whole county outline, rivers and lakes included; parts FEMA hasn’t mapped count as zero.

From the storm reports

Flash Flood · May 25, 2025. A short wave trough moving out of northern Mexico into the Southern High Plains brought widespread and intense convection to the South Plains and Rolling Plains of West Texas on the afternoon and evening of the 25th. This short wave trough brought the necessary large scale ascent that was missing the past several days to create the more widespread activity on the 25th. At the same time, a slow moving cold front wa…

Flash Flood · Apr 24, 2025. Another day of widespread severe thunderstorms occurred on the afternoon and evening hours of the 24th. Persistent but weak southwesterly flow aloft increased on the 24th which allowed supercell thunderstorms to produce giant hail. Increased low level southeasterly winds also allowed these thunderstorms to produce numerous tornadoes. Thunderstorms initially developed late in the afternoon along a dryline along the…

Flash Flood · May 28, 2023. Scattered supercell thunderstorms developed on the afternoon of the 28th and persisted through the evening producing several severe storms despite weak background forcing. Strong instability developed while the atmosphere became uncapped which allowed these supercell thunderstorms to develop. A slow moving storm near Vigo Park produced a brief tornado over an open field. More widespread thunderstorms evolved late…

Flood · Apr 22, 2015. Early this morning, a series of outflow boundaries moved south across the southern Texas Panhandle and much of the Rolling Plains. The most organized of these boundaries would eventually retreat north before stalling from near Hereford (Deaf Smith County, WFO AMA) southeast to Paducah (Cottle County). This boundary provided the focus for an intense and long-lived supercell that developed west of Hereford by mid-af…

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Motley County

If a building in Motley 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.
