From the storm reports

Flash Flood · Jun 24, 2025. A continued monsoonal weather pattern resulted in scattered, slow-moving thunderstorms across the region. Localized flash flooding was reported in low-lying areas of I-10 and within normally dry draws.

Flood · Jun 30, 2021. An upper level low pressure was to the west of the region which aided in atmospheric lift over Southeast New Mexico and West Texas. Convergence was also over the area which allowed for more lift. An abundance of moisture was in place. These conditions resulted in flooding across Culberson County.

Flash Flood · Jun 28, 2021. An upper level low pressure system was over the Arizona and New Mexico border. There was a stationary front across the area which provided additional lift over West Texas. Abundant moisture was continuing to move into the region. These conditions resulted in rain and thunderstorms developing and moving over the same areas producing flash flooding across West Texas.

Flood · Sep 23, 2014. Weak upper ridging was to the west of the region. Decent moisture and lift were across the area allowing for light showers across southeast New Mexico and along and west of the Upper Trans Pecos in West Texas. The soils remained saturated and rivers were high so flooding continued for portions of southeast New Mexico and West Texas.

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.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Culberson County

If a building in Culberson 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.
