How Pushmataha County floods

Flash flooding from slow-moving thunderstorms dominates the flood risk in Pushmataha County, Oklahoma. Over the last 30 years, the NOAA Storm Events Database recorded 40 flash flood events resulting in one death, alongside 17 general flood events resulting in one additional death.

Severe weather events are frequently driven by slow-moving cold fronts or high atmospheric moisture that causes storms to train repeatedly over the same areas. For example, on May 25, 2016, slow-moving thunderstorms dropped five to seven inches of rain in less than four hours across northwestern Pushmataha County and northeastern Atoka County, leading to moderate flooding of the Kiamichi River near Antlers. Similarly, on July 5, 2017, thunderstorms produced locally heavy rainfall of three to five inches, with some areas exceeding eight inches.

Properties situated near rivers and streams, as well as those prone to rapid accumulation from intense rainfall, should pay the most attention to local flood risks. Federal Emergency Management Agency records for the county indicate a single claim in the unshaded Zone X, which logged an average payout of $0 and an average recorded water depth of 0 inches.

From the storm reports

Flash Flood · Aug 19, 2021. Thunderstorms developed across portions of southeastern Oklahoma during the early morning hours of the 19th. A very moist air mass across the region and weak wind flow aloft resulted in slow-moving thunderstorms that produced very heavy rainfall, some of which resulted in flash flooding.

Flood · May 1, 2019. Multiple rounds of thunderstorm activity moved across eastern Oklahoma on April 30th into the morning hours of May 1st as a cold front slowly moved through the area. Atmospheric moisture was unseasonably high and steering currents were parallel to the front, both of which contributed to widespread, heavy rainfall as thunderstorms were very efficient rain-producers and tended to move repeatedly over the same areas.…

Flash Flood · Jul 5, 2017. Thunderstorms developed over southeastern Oklahoma during the early morning hours of July 5th, as a slow moving cold front moved into the area. These thunderstorms produced locally heavy rainfall of three to five inches across much of southeastern Oklahoma, with areas of rain exceeding eight inches observed. This heavy rainfall resulted in some flash flooding.

Flood · May 25, 2016. Slow-moving thunderstorms resulted in widespread two to four inches of rain across southeastern Oklahoma during the early morning hours of May 25th. Northwestern portions of Pushmataha County and northeastern Atoka County received between five and seven inches of rain in less than four hours that morning. This excessive rainfall resulted in moderate flooding of the Kiamichi River near Antlers.

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.

Flood insurance in Pushmataha County

If a building in Pushmataha 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.
