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

From the storm reports

Flash Flood · Aug 12, 2022. As the upper-level high pressure built over the Great Plains on August 12, 2022, much drier air pushed into eastern and central New Mexico. This led to a downtrend in thunderstorm coverage across much of the area while the monsoonal moisture plume focued across western New Mexico kept conditions relatively more active there. Despite this drier air, isolated thunderstorms were still able to form across the northern…

Flash Flood · Jul 21, 2021. With an area of high pressure centered over the Four Corners region, persistent northeasterly flow combined with sufficient low-level moisture supported another active monsoon day across northern and central New Mexico. Thunderstorm activity initiated over the northern high terrain by early afternoon, and thunderstorms intensified as the afternoon progressed as they tracked in a general southeasterly direction. On…

Flash Flood · Aug 15, 2021. An abundant amount of moisture in place over northern and central New Mexico led to another active monsoon day on August 15, 2021. With southerly flow at the surface and northerly flow aloft, shear profiles were more supportive for stronger thunderstorms and heavy rainfall. Thunderstorms initially formed over the high terrain of Colorado and New Mexico by early afternoon before propagating southward through the ev…

Flash Flood · Aug 9, 2018. The center of upper level high pressure shifted farther west into Arizona on August 9th and allowed weaker steering flow to become more north to south across New Mexico. Deep moisture and strong instability over the state allowed numerous showers and thunderstorms to develop over the higher terrain during the early afternoon before spreading into nearby highlands and valleys through the evening. A powerful thunder…

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.

Flood insurance in Taos County

If a building in Taos 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.
