From the storm reports

Flash Flood · May 4, 2024. A favorable weather pattern for widespread severe weather was in place across west central Texas during early May. There was an upper level southwest flow and a sharp dryline in the area. Also, extreme instability was present along with strong vertical wind shear during the late afternoon and evening hours. A supercell thunderstorm produced a tornado in Crockett County. Also, severe thunderstorms produced large ha…

Flash Flood · Sep 3, 2024. A significant heavy rainfall event occurred early in the month across mainly the Concho Valley, northern Heartland and southern Big Country due to a slow moving upper level storm system and a very moist tropical airmass, which was near record levels for early September. Numerous showers and a few thunderstorms produced localized heavy rainfall amounts greater than 10 inches across portions of northeast Tom Green,…

Flash Flood · May 2, 2019. On May 1, a very unstable airmass, dryline and a residual outflow boundary combined across the Big Country or the region north of Interstate 20 to trigger a few supercell thunderstorms. These ingredients resulted in two tornado reports and a few hail reports. By May 3, an upper level disturbance moved into West Central Texas and caused more severe storms to develop. These storms produced large hail on May 3. T…

Flash Flood · Sep 29, 2012. A stationary frontal boundary interacting with an influx of upper level tropical moisture from the Pacific and low level moisture from the Gulf of Mexico resulted in widespread heavy rainfall across West Central Texas. The heaviest rain fell from Crockett County to Brownwood and north to I20. Twenty four hour rainfall totals averaged around 3 to 6 inches. However, portions of Tom Green, Runnels, Concho, and Cok…

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 Concho County

If a building in Concho 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.
